To get started, try sending an SMS message either by using our API and XML documents, or via PHLO, our visual design tool, which allows you to create message flows using an intuitive canvas and deploy them with few clicks.

Using PHLO

Set up your Python Flask dev environment

You must set up and install Python, Flask, and Plivo’s Python SDK before you send your first message.

Install Python

Download and install Python from its official site.

Install Flask and the Plivo Python SDK

Create a projects directory and change into it.

$ mkdir mypythonapp
$ cd mypythonapp

Install the modules using pip.

pip install flask plivo

Alternatively, you can download the Plivo source code from this repo and run

python setup.py install

We recommend that you use virtualenv to manage and segregate your Python environments, instead of using sudo with your commands and overwriting dependencies.

Send your first outbound SMS/MMS message

You can create and deploy a PHLO to send your first outbound SMS message with a few clicks on the PHLO canvas, and trigger it with some simple code.

Create the PHLO

SMS

MMS

To create a PHLO, visit the PHLO page of the Plivo console. If this is your first PHLO, the PHLO page will be empty.

• Click Create New PHLO.

• In the Choose your use case pop-up, click Build my own. The PHLO canvas will appear with the Start node.

  Note: The Start node is the starting point of any PHLO. It lets you trigger a PHLO to start upon one of three actions: incoming SMS message, incoming, or API request.

• From the list of components on the left-hand side, drag and drop the Send Message component onto the canvas. When a component is placed on the canvas it becomes a node.

• Draw a line to connect the Start node’s API Request trigger state to the Send Message node.

• In the Configuration pane at the right of the canvas, configure the Send Message node with a sender ID in the From field. Enter the destination number you wish to send a message to in the To field. Put your message in the Text field.

  Note: You can define a static payload by specifying values when you create the PHLO, or define a dynamic payload by passing values through Liquid templating parameters when you trigger the PHLO from your application.

• If you’d like to send an MMS message, configure the Media URLs field with the media files you’d like to send.

• Once you’ve configured the node, click Validate to save the configuration.

• After you complete the configuration, give the PHLO a name by clicking in the upper left, then click Save.

Your PHLO is now ready to test.

Trigger the PHLO

You integrate a PHLO into your application workflow by making an API request to trigger the PHLO with the required payload — the set of parameters you pass to the PHLO. You can define a static payload by specifying values when you create the PHLO, or define a dynamic payload by passing values through parameters when you trigger the PHLO from your application.

In either case, you need your Auth ID and Auth Token, which you can get from the overview page of the Plivo console.

You also need the PHLO ID, which you can copy from the PHLO list page.

With a static payload

When you configure values when creating the PHLO, they act as a static payload.

Code

Create a file called trigger_phlo.py and paste into it this code.

import plivo

auth_id = '<auth_id>'
auth_token = '<auth_token>'
phlo_id = '<phlo_id>'
phlo_client = plivo.phlo.RestClient(auth_id=auth_id, auth_token=auth_token)
phlo = phlo_client.phlo.get(phlo_id)
response = phlo.run()
print str(response)

With a dynamic payload

To use dynamic values for the parameters, use Liquid templating parameters when you create the PHLO …

… and pass the values from your code when you trigger it.

Code

Create a file called trigger_phlo.py and paste into it this code.

import plivo

auth_id = '<auth_id>'
auth_token = '<auth_token>'
phlo_id = '<phlo_id>'
payload = {"From" : "<sender_id>","To" : "<destination_number>"}
phlo_client = plivo.phlo.RestClient(auth_id=auth_id, auth_token=auth_token)
phlo = phlo_client.phlo.get(phlo_id)
response = phlo.run(**payload)
print str(response)

Replace the auth placeholders with your authentication credentials from the Plivo console. Replace the phlo_id placeholder with your PHLO ID from the Plivo console. Replace the phone number placeholders with actual phone numbers in E.164 format (for example, [phone]).

Test

Save the file and run it.

$ python trigger_phlo.py

Receive your first inbound SMS/MMS message

You can create and deploy a PHLO to receive an inbound text message with a few clicks on the PHLO canvas, without writing a single line of code.

Prerequisite

To receive incoming text messages, you must have an SMS-enabled Plivo phone number. You can rent numbers from the Numbers page of the Plivo console, or by using the Numbers API.

Create the PHLO

SMS

MMS

To create a PHLO, visit the PHLO page of the Plivo console. If this is your first PHLO, the PHLO page will be empty.

• In the Choose your use case pop-up, click Build my own. The PHLO canvas will appear with the Start node.

  Note: The Start node is the starting point of any PHLO. It lets you trigger a PHLO to start upon one of three actions: incoming SMS message, incoming call, or API request.

• From the list of components on the left-hand side, drag and drop the HTTP Request component onto the canvas. When a component is placed on the canvas it becomes a node.

• Draw a line to connect the Start node’s Incoming Message trigger state to the HTTP Request node.

• In the Configuration pane at the right of the canvas, configure the HTTP Request node. Specify the address of your web server and specify that from, to, and text fields should be passed along with the request.

• Once you’ve configured the node, click Validate to save the configuration.

• After you complete the configuration, give the PHLO a name by clicking in the upper left, then click Save.

Assign the PHLO to a Plivo number

Once you’ve created and configured your PHLO, assign it to a Plivo number.

• On the Numbers page of the console, under Your Numbers, click the phone number you want to use for the PHLO.

• In the Number Configuration box, select PHLO from the Application Type drop-down.

• From the PHLO Name drop-down, select the PHLO you want to use with the number, then click Update Number.

Test

You can now send a text message to your Plivo phone number and see how the inbound text is handled.

For more information about creating a PHLO application, see the PHLO Getting Started guide. For information on components and their variables, see the PHLO Components Library.

Forward an incoming SMS/MMS message

You can create and deploy a workflow to implement text message forwarding with a few clicks on the PHLO canvas.

For more information about creating a PHLO application, see the PHLO Getting Started guide. For information on components and their variables, see the PHLO Components Library.

More use cases

We illustrate more than a dozen use cases with code for both PHLO and API/XML on our documentation pages.

Using API

Install Python, Flask, and the Plivo Python SDK

You must set up and install Python, Flask, and Plivo’s Python SDK before you send your first SMS message.

Install Python

Download and install Python from its official site.

Install Flask and the Plivo Python SDK

Create a project directory and change into it.

$ mkdir mypythonapp
$ cd mypythonapp

Install Flask and the Plivo SDK using pip.

$ pip install flask plivo

Alternatively, you can download the source code and run

$ python setup.py install

We recommend that you use virtualenv to manage and segregate your Python environments, instead of using sudo with your commands and overwriting dependencies.

Send your first outbound SMS/MMS message

You must have a Plivo phone number to send messages to the US or Canada; you can rent a Plivo number from Phone Numbers > Buy Numbers on the Plivo console or via the Numbers API.

Create a file called SendSMS.py and paste into it this code.

SMS

from flask import Flask, Response
from plivo import plivo

app = Flask(__name__)

@app.route('/send_sms/', methods=['GET', 'POST'])
def outbound_sms():
    client = plivo.RestClient('<auth_id>','<auth_token>')
    response = client.messages.create(
      src='<sender_id>',
      dst='<destination_number>',
      text='Hello, from Flask!')
    return Response(response.to_string())

if __name__ == '__main__':
    app.run(host='0.0.0.0', debug=True)

MMS

from flask import Flask, Response
from plivo import plivo

app = Flask(__name__)

@app.route('/send_mms/', methods=['GET', 'POST'])
def outbound_mms():
    client = plivo.RestClient('<auth_id>','<auth_token>')
    response = client.messages.create(
        src='<sender_id>',
        dst='<destination_number>',
        media_ids=['801c2056-33ab-499c-80ef-58b574a462a2'],
        text='Hello, MMS from Flask!',
        media_urls=['https://media.giphy.com/media/26gscSULUcfKU7dHq/source.gif'],
        type_='mms')
    return Response(response.to_string())

if __name__ == '__main__':
    app.run(host='0.0.0.0', debug=True)

Replace the auth placeholders with your authentication credentials from the Plivo console. Replace the phone number placeholders with actual phone numbers in E.164 format (for example, [phone]). In countries other than the US and Canada you can use a sender ID for the message source.

Note: We recommend that you store your credentials in the auth_id and auth_token environment variables to avoid the possibility of accidentally committing them to source control. If you do this, you can initialize the client with no arguments and Plivo will automatically fetch the values from the environment variables. You can use os.environ to store environment variables and fetch them when initializing the client.

Save the file and run it.

$ python SendSMS.py

Receive your first inbound SMS/MMS message

To receive incoming messages, you must have a Plivo phone number that supports SMS; you can rent numbers from the Numbers page of the Plivo console or by using the Numbers API.

Set up a Flask server

Create a file called receive_sms.py and paste into it this code.

SMS

from flask import Flask, request

app = Flask(__name__)

@app.route('/receive_sms/', methods=['GET', 'POST'])
def inbound_sms():

    from_number = request.values.get('From')
    to_number = request.values.get('To')
    text = request.values.get('Text')
    print('Message received - From: %s, To: %s, Text: %s' %(from_number, to_number, text))

    return 'Message Received'

if __name__ == '__main__':
    app.run(host='0.0.0.0', debug=True)

MMS

from flask import Flask, request

app = Flask(__name__)

@app.route('/receive_mms/', methods=['GET', 'POST'])
def inbound_mms():

    from_number = request.values.get('From')
    to_number = request.values.get('To')
    text = request.values.get('Text')
    media_url = request.values.get('Media0')
    print('Message received - From: %s, To: %s, Text: %s, Media: %s' %(from_number, to_number, text, media_url))

    return 'Message Received'

if __name__ == '__main__':
    app.run(host='0.0.0.0', debug=True)

Save the file and run it.

$ python receive_sms.py

And you should see your basic server app in action on http://localhost:5000/receive_sms/.

Expose your local server to the internet

To receive incoming messages, your local server must connect with Plivo API services. For that, we recommend using ngrok, which exposes local servers running behind NATs and firewalls to the public internet over secure tunnels. Using ngrok, you can set webhooks that can talk to the Plivo server.

Run ngrok on the command line, specifying the port that hosts the application on which you want to receive messages (80 in this case):

$ ./ngrok http 80

This starts the ngrok server on your local server. Ngrok will display a forwarding link that you can use as a webhook to access your local server over the public network.

Now people can send messages to your Plivo number.

Create a Plivo application to receive messages

Associate the controller you created with Plivo by creating a Plivo application. Visiting Messaging > Applications and click Add New Application. You can also use Plivo’s Application API.

Give your application a name — we called ours Receive SMS. Enter the server URL you want to use (for example https://<yourdomain>.com/receive_sms/) in the Message URL field and set the method to POST. Click Create Application to save your application.

Assign a Plivo number to your application

Navigate to the Numbers page and select the phone number you want to use for this application.

From the Application Type drop-down, select XML Application.

From the Plivo Application drop-down, select Receive SMS (the name we gave the application).

Click Update Number to save.

Test

Send a text message to the Plivo number you specified using any phone.

Reply to an incoming SMS/MMS message

To receive incoming messages, you must have a Plivo phone number that supports SMS; you can rent numbers from the Numbers page of the Plivo console or by using the Numbers API.

Set up a Flask server

Create a file called reply_to_sms.py and paste into it this code.

from flask import Flask, request, make_response, Response
from plivo import plivoxml

app = Flask(__name__)

@app.route('/reply_to_sms/', methods=['GET', 'POST'])
def reply_sms():

    from_number = request.values.get('From')
    to_number = request.values.get('To')
    text = request.values.get('Text')
    print('Message received - From: %s, To: %s, Text: %s' %(from_number, to_number, text))
    
    # send the details to generate an XML
    response = plivoxml.ResponseElement()
    response.add(
        plivoxml.MessageElement(
            'This is an automatic response',
            src=to_number,  
            dst=from_number))
    print(response.to_string())  # Prints the XML
    # Returns the XML
    return Response(response.to_string(), mimetype='application/xml')

if __name__ == '__main__':
    app.run(host='0.0.0.0', debug=True)

If you haven’t done so already, expose your local server to the internet.

Create a Plivo application to reply to messages

Associate the controller you created with Plivo by creating a Plivo application. Visiting Messaging > Applications and click Add New Application. You can also use Plivo’s Application API.

Give your application a name — we called ours Reply Incoming SMS. Enter the server URL you want to use (for example http://<yourdomain>.com/replysms/) in the Message URL field and set the method to POST. Click Create Application to save your application.

Assign a Plivo number to your application

Navigate to the Numbers page and select the phone number you want to use for this application.

From the Application Type drop-down, select XML Application.

From the Plivo Application drop-down, select Reply Incoming SMS (the name we gave the application).

Click Update Number to save.

Test

Send a text message to the Plivo number you specified using any phone. You should receive a reply.

This command creates an SMSProj directory in your projects directory.

Once you’ve set up your development environment, you can start sending and receiving messages using PHLO, our visual workflow design studio, or using our APIs and XML documents. Here are three common use cases to get you started.

Send your first outbound SMS/MMS message

You can create and deploy a PHLO to send your first outbound SMS message with a few clicks on the PHLO canvas, and trigger it with some simple code.

Create the PHLO

SMS

MMS

• Click Create New PHLO.

• In the Choose your use case pop-up, click Build my own. The PHLO canvas will appear with the Start node.

  Note: The Start node is the starting point of any PHLO. It lets you trigger a PHLO to start upon one of three actions: incoming SMS message, incoming, or API request.

• From the list of components on the left-hand side, drag and drop the Send Message component onto the canvas. When a component is placed on the canvas it becomes a node.

• Draw a line to connect the Start node’s API Request trigger state to the Send Message node.

• In the Configuration pane at the right of the canvas, configure the Send Message node with a sender ID in the From field. Enter the destination number you wish to send a message to in the To field. Put your message in the Text field.

  Note: You can define a static payload by specifying values when you create the PHLO, or define a dynamic payload by passing values through Liquid templating parameters when you trigger the PHLO from your application.

• If you’d like to send an MMS message, configure the Media URLs field with the media files you’d like to send.

• Once you’ve configured the node, click Validate to save the configuration.

• After you complete the configuration, give the PHLO a name by clicking in the upper left, then click Save.

Your PHLO is now ready to test.

Trigger the PHLO

You integrate a PHLO into your application workflow by making an API request to trigger the PHLO with the required payload — the set of parameters you pass to the PHLO. You can define a static payload by specifying values when you create the PHLO, or define a dynamic payload by passing values through parameters when you trigger the PHLO from your application.

In either case, you need your Auth ID and Auth Token, which you can get from the overview page of the Plivo console.

You also need the PHLO ID, which you can copy from the PHLO list page.

Change to the project directory and run this command to create a Django application for outbound SMS.

$ python manage.py startapp outboundsms

This command creates an outboundsms directory in your SMSProj directory.

With a static payload

When you configure values when creating the PHLO, they act as a static payload.

Code

Edit outboundsms/views.py and paste into it this code.

from django.conf import settings
from django.http import HttpResponse
from django.views.decorators.csrf import csrf_exempt
import plivo

@csrf_exempt
def outboundcall_response(request):

  auth_id = '<auth_id>'
  auth_token = '<auth_token>'
  phlo_id = '<phlo_id>'
  phlo_client = plivo.phlo.RestClient(auth_id=auth_id, auth_token=auth_token)
  phlo = phlo_client.phlo.get(phlo_id)
  response = phlo.run()
  return HttpResponse(response)

Replace the auth placeholders with your authentication credentials from the Plivo console. Replace the phlo_id placeholder with your PHLO ID from the Plivo console.

With a dynamic payload

To use dynamic values for the parameters, use Liquid templating parameters when you create the PHLO …

… and pass the values from your code when you trigger it.

Code

Edit outboundsms/views.py and paste into it this code.

from django.conf import settings
from django.http import HttpResponse
from django.views.decorators.csrf import csrf_exempt
import plivo

@csrf_exempt
def outboundcall_response(request):
  auth_id = '<auth_id>'
  auth_token = '<auth_token>'
  phlo_id = '<phlo_id>'
  payload = {"From" : "<sender_id>","To" : "<destination_number>"}
  phlo_client = plivo.phlo.RestClient(auth_id=auth_id, auth_token=auth_token)
  phlo = phlo_client.phlo.get(phlo_id)
  response = phlo.run(**payload)
  return HttpResponse(response)

Replace the auth placeholders with your authentication credentials from the Plivo console. Replace the phlo_id placeholder with your PHLO ID from the Plivo console. Replace the phone number placeholders with actual phone numbers in E.164 format (for example, [phone]).

Add a route

Create a file outboundsms/urls.py and paste into it this code.

from django.conf.urls import url
from . import views
urlpatterns = [
   url(r'^$', views.outboundsms_response, name='outboundsms'),
]

Add a route for the outboundsms app into the urls.py of your SMSProj project. Edit SMSProj/urls.py and add this code.

from django.conf.urls import include, url
from django.contrib import admin

urlpatterns = [
   url(r'^outboundsms/', include('outboundsms.urls')),
   url(r'^admin/', admin.site.urls),
   ]

   return HttpResponse(response)

Replace the auth placeholders with your authentication credentials from the Plivo console. Replace the phone number placeholders with actual phone numbers in E.164 format (for example, [phone]). In countries other than the US and Canada you can use a sender ID for the message source.

Note: We recommend that you store your credentials in the auth_id and auth_token environment variables to avoid the possibility of accidentally committing them to source control. If you do this, you can initialize the client with no arguments and Plivo will automatically fetch the values from the environment variables. You can use os.environ to store environment variables and fetch them when initializing the client.

Add a route

Create a file sendsms/urls.py and paste into it this code.

from django.conf.urls import url
from . import views
urlpatterns = [
   url(r'^$', views.sendsms_response, name='sendsms'),
]

Add a route for the sendsms app into the urls.py of your SMSProj project. Edit SMSProj/urls.py and paste into it this code.

from django.conf.urls import include, url
from django.contrib import admin

urlpatterns = [
   url(r'^sendsms/', include('sendsms.urls')),
   url(r'^admin/', admin.site.urls),
   ]

Test

Run your code.

$ python3 manage.py runserver

Receive your first inbound SMS/MMS message

To receive incoming messages, you must have a Plivo phone number that supports SMS; you can rent numbers from the Numbers page of the Plivo console or by using the Numbers API.

Create a Django app

Change to the project directory and create a Django app to handle incoming calls.

$ python3 manage.py startapp receivesms

Edit receivesms/views.py file and paste into it this code.

Add a route

Create a file receivesms/urls.py and paste into it this code.

from django.conf.urls import url
from . import views
urlpatterns = [
   url(r'^$', views.receivesms_response, name='receivesms'),
]

   url(r'^outboundsms/', include('outboundsms.urls')),
   url(r'^receivesms/', include('receivesms.urls')),
   url(r'^admin/', admin.site.urls),
   ]

Run your code.

$ python3 manage.py runserver

Expose your local server to the internet

To receive incoming messages, your local server must connect with Plivo API services. For that, we recommend using ngrok, which exposes local servers running behind NATs and firewalls to the public internet over secure tunnels. Using ngrok, you can set webhooks that can talk to the Plivo server.

Note: Before starting the service, add ngrok i**hosts list in the settings.py file in your project.

ALLOWED_HOSTS = ['.ngrok.io']

Run ngrok on the command line, specifying the port that hosts the application on which you want to receive messages (8000 in this case):

$ ./ngrok http 8000

This starts the ngrok server on your local server. Ngrok will display a forwarding link that you can use as a webhook to access your local server over the public network.

Now people can send messages to your Plivo number.

Create a Plivo application to receive messages

Associate the controller you created with Plivo by creating a Plivo application. Visiting Messaging > Applications and click Add New Application. You can also use Plivo’s Application API.

Give your application a name — we called ours Receive SMS. Enter the server URL you want to use (for example https://<yourdomain>.com/receive_sms/) in the Message URL field and set the method to POST. Click Create Application to save your application.

Assign a Plivo number to your application

Navigate to the Numbers page and select the phone number you want to use for this application.

From the Application Type drop-down, select XML Application.

From the Plivo Application drop-down, select Receive SMS (the name we gave the application).

Click Update Number to save.

Test

Send a text message to the Plivo number you specified using any phone.

Reply to an incoming SMS/MMS message

To receive incoming messages, you must have a Plivo phone number that supports SMS; you can rent numbers from the Numbers page of the Plivo console or by using the Numbers API.

$ python manage.py startapp replysms

Edit replysms/views.py and paste into it this code.

from django.conf import settings
from django.http import HttpResponse
from django.views.decorators.csrf import csrf_exempt
from plivo import plivoxml


@csrf_exempt
def reply_response(request):

    from_number = form.cleaned_data["From"]

   # send the details to generate an XML
    response = plivoxml.ResponseElement()
    response.add(
        plivoxml.MessageElement(
            'This is an automatic response',
            src=to_number,  
            dst=from_number))
    print(response.to_string())  # Prints the XML
   return HttpResponse(response.to_string(), content_type='text/xml')

Add a route

Create a file replysms/urls.py and paste into it this code.

from django.conf.urls import url
from . import views
urlpatterns = [
   url(r'^$', views.reply_response, name='replysms'),
]

Add a route for the replysms app into the urls.py of your project, SMSProj. Edit SMSProj/urls.py and paste into it this code.

from django.conf.urls import include, url
from django.contrib import admin

urlpatterns = [
   url(r'^outboundsms/', include('outboundsms.urls')),
   url(r'^receivesms/', include('receivesms.urls')),
   url(r'^replysms/', include('replysms.urls')),
   url(r'^admin/', admin.site.urls),
   ]

If you haven’t done so already, expose your local server to the internet.

Create a Plivo application to reply to messages

Associate the controller you created with Plivo by creating a Plivo application. Visiting Messaging > Applications and click Add New Application. You can also use Plivo’s Application API.

Give your application a name — we called ours Reply Incoming SMS. Enter the server URL you want to use (for example http://<yourdomain>.com/replysms/) in the Message URL field and set the method to POST. Click Create Application to save your application.

Assign a Plivo number to your application

Navigate to the Numbers page and select the phone number you want to use for this application.

More use cases

We illustrate more than a dozen use cases with code for both API/XML and PHLO on our documentation pages.

Python & FastAPI

Get Started with Python Using the FastAPI Framework

Sign up for a Plivo account

When you sign up with Plivo, we give you a free trial account and free credits to experiment with and learn about our services. You can add a number to your account to start testing the full range of our voice and SMS service features.

Follow these steps to get a free trial account:

1. Sign up with your work email address.
2. Check your inbox for an activation email message from Plivo. Click on the link in the message to activate your account.
3. Enter your mobile number to complete the phone verification step.

Sign up with your work email address

If you have any issues creating a Plivo account, please contact our support team for assistance.

To get started, try sending an SMS message either by using our API and XML documents, or via PHLO, our visual design tool, which allows you to create message flows using an intuitive canvas and deploy them with few clicks.

Using PHLO

Set up your Python FastAPI dev environment

You must set up and install Python, FastAPI, and Plivo’s Python SDK before you send your first message.

Install Python

Download and install Python from its official site.

Install FastAPI and the Plivo Python SDK

Create a projects directory and change into it.

$ mkdir mypythonapp
$ cd mypythonapp

Install the FastAPI framework using pip.

$ pip install fastapi

Install an ASGI server for production. Uvicorn and Hypercorn are two good ones.

$ pip install uvicorn

Install the Plivo Python SDK.

$ pip install plivo

We recommend that you use virtualenv to manage and segregate your Python environments, instead of using sudo with your commands and overwriting dependencies.

Send your first outbound SMS/MMS message

You can create and deploy a PHLO to send your first outbound SMS message with a few clicks on the PHLO canvas, and trigger it with some simple code.

Create the PHLO

SMS

MMS

To create a PHLO, visit the PHLO page of the Plivo console. If this is your first PHLO, the PHLO page will be empty.

• Click Create New PHLO.

• In the Choose your use case pop-up, click Build my own. The PHLO canvas will appear with the Start node.

  Note: The Start node is the starting point of any PHLO. It lets you trigger a PHLO to start upon one of three actions: incoming SMS message, incoming, or API request.

• From the list of components on the left-hand side, drag and drop the Send Message component onto the canvas. When a component is placed on the canvas it becomes a node.

• Draw a line to connect the Start node’s API Request trigger state to the Send Message node.

• In the Configuration pane at the right of the canvas, configure the Send Message node with a sender ID in the From field. Enter the destination number you wish to send a message to in the To field. Put your message in the Text field.

  Note: You can define a static payload by specifying values when you create the PHLO, or define a dynamic payload by passing values through Liquid templating parameters when you trigger the PHLO from your application.

• If you’d like to send an MMS message, configure the Media URLs field with the media files you’d like to send.

• Once you’ve configured the node, click Validate to save the configuration.

• After you complete the configuration, give the PHLO a name by clicking in the upper left, then click Save.

Your PHLO is now ready to test.

Trigger the PHLO

You integrate a PHLO into your application workflow by making an API request to trigger the PHLO with the required payload — the set of parameters you pass to the PHLO. You can define a static payload by specifying values when you create the PHLO, or define a dynamic payload by passing values through parameters when you trigger the PHLO from your application.

In either case, you need your Auth ID and Auth Token, which you can get from the overview page of the Plivo console.

You also need the PHLO ID, which you can copy from the PHLO list page.

With a static payload

When you configure values when creating the PHLO, they act as a static payload.

Code

Create a file called trigger_phlo.py and paste into it this code.

import plivo
from typing import Optional
from fastapi import FastAPI

app = FastAPI()

@app.get("/outbound/")
def make_call():

  auth_id = '<auth_id>'
  auth_token = '<auth_token>'
  phlo_id = '<phlo_id>'
  phlo_client = plivo.phlo.RestClient(auth_id=auth_id, auth_token=auth_token)
  phlo = phlo_client.phlo.get(phlo_id)
  response = phlo.run()
  return response

Replace the auth placeholders with your authentication credentials from the Plivo console. Replace the phlo_id placeholder with your PHLO ID from the Plivo console.

With a dynamic payload

To use dynamic values for the parameters, use Liquid templating parameters when you create the PHLO …

… and pass the values from your code when you trigger it.

Code

Create a file called trigger_phlo.py and paste into it this code.

import plivo
from typing import Optional
from fastapi import FastAPI

app = FastAPI()

@app.get("/outbound/")
def make_call():
    auth_id = '<auth_id>'
    auth_token = '<auth_token>'
    phlo_id = '<phlo_id>'
    payload = {"From" : "<sender_id>","To" : "<destination_number>"}
    phlo_client = plivo.phlo.RestClient(auth_id=auth_id, auth_token=auth_token)
    phlo = phlo_client.phlo.get(phlo_id)
    response = phlo.run(**payload)
    return response

Replace the auth placeholders with your authentication credentials from the Plivo console. Replace the phlo_id placeholder with your PHLO ID from the Plivo console. Replace the phone number placeholders with actual phone numbers in E.164 format (for example, [phone]).

Test

Save the file and run your code.

$ uvicorn trigger_phlo:app --reload

  Note: The Start node is the starting point of any PHLO. It lets you trigger a PHLO to start upon one of three actions: incoming SMS message, incoming call, or API request.

• From the list of components on the left-hand side, drag and drop the HTTP Request component onto the canvas. When a component is placed on the canvas it becomes a node.

• Draw a line to connect the Start node’s Incoming Message trigger state to the HTTP Request node.

• In the Configuration pane at the right of the canvas, configure the HTTP Request node. Specify the address of your web server and specify that from, to, and text fields should be passed along with the request.

• Once you’ve configured the node, click Validate to save the configuration.

• After you complete the configuration, give the PHLO a name by clicking in the upper left, then click Save.

  Note: You can define a static payload by specifying values when you create the PHLO, or define a dynamic payload by passing values through Liquid templating parameters when you trigger the PHLO from your application.

• If you’d like to send an MMS message, configure the Media URLs field with the media files you’d like to send.

• Once you’ve configured the node, click Validate to save the configuration.

• After you complete the configuration, give the PHLO a name by clicking in the upper left, then click Save.

Your PHLO is now ready to test.

Trigger the PHLO

You integrate a PHLO into your application workflow by making an API request to trigger the PHLO with the required payload — the set of parameters you pass to the PHLO. You can define a static payload by specifying values when you create the PHLO, or define a dynamic payload by passing values through parameters when you trigger the PHLO from your application.

In either case, you need your Auth ID and Auth Token, which you can get from the overview page of the Plivo console.

You also need the PHLO ID, which you can copy from the PHLO list page.

With a static payload

When you configure values when creating the PHLO, they act as a static payload.

Code

Create a file called trigger_phlo.py and paste into it this code.

import plivo
from sanic import Sanic
from sanic.response import text

app = Sanic('Plivo SMS App')

@app.route('/outbound', methods=['POST', 'GET'])
async def make_call(request):
  auth_id = '<auth_id>'
  auth_token = '<auth_token>'
  phlo_id = '<phlo_id>'
  phlo_client = plivo.phlo.RestClient(auth_id=auth_id, auth_token=auth_token)
  phlo = phlo_client.phlo.get(phlo_id)
  response = phlo.run()
  return text(response, content_type="text/json")

if __name__ == "__main__":
  app.run(host="0.0.0.0", port=8000)

Replace the auth placeholders with your authentication credentials from the Plivo console. Replace the phlo_id placeholder with your PHLO ID from the Plivo console.

With a dynamic payload

To use dynamic values for the parameters, use Liquid templating parameters when you create the PHLO …

… and pass the values from your code when you trigger it.

Code

Create a file called trigger_phlo.py and paste into it this code.

import plivo
from sanic import Sanic
from sanic.response import text

app = Sanic('Plivo SMS App')

@app.route('/outbound', methods=['POST', 'GET'])
async def make_call(request):
    auth_id = '<auth_id>'
    auth_token = '<auth_token>'
    phlo_id = '<phlo_id>'
    payload = {"from" : "<sender_id>","to" : "<destination_number>"}
    phlo_client = plivo.phlo.RestClient(auth_id=auth_id, auth_token=auth_token)
    phlo = phlo_client.phlo.get(phlo_id)
    response = phlo.run(**payload)
    return text(response, content_type="text/json")

if __name__ == "__main__":
  app.run(host="0.0.0.0", port=8000)

Save the file and run it.

$ python trigger_phlo.py

Receive your first inbound SMS/MMS message

You can create and deploy a PHLO to receive an inbound text message with a few clicks on the PHLO canvas, without writing a single line of code.

Prerequisite

To receive incoming text messages, you must have an SMS-enabled Plivo phone number. You can rent numbers from the Numbers page of the Plivo console, or by using the Numbers API.

Create the PHLO

SMS

MMS

To create a PHLO, visit the PHLO page of the Plivo console. If this is your first PHLO, the PHLO page will be empty.

• Click Create New PHLO.

• In the Choose your use case pop-up, click Build my own. The PHLO canvas will appear with the Start node.

  Note: The Start node is the starting point of any PHLO. It lets you trigger a PHLO to start upon one of three actions: incoming SMS message, incoming call, or API request.

• From the list of components on the left-hand side, drag and drop the HTTP Request component onto the canvas. When a component is placed on the canvas it becomes a node.

• Draw a line to connect the Start node’s Incoming Message trigger state to the HTTP Request node.

• In the Configuration pane at the right of the canvas, configure the HTTP Request node. Specify the address of your web server and specify that from, to, and text fields should be passed along with the request.

• Once you’ve configured the node, click Validate to save the configuration.

• After you complete the configuration, give the PHLO a name by clicking in the upper left, then click Save.

Assign the PHLO to a Plivo number

Once you’ve created and configured your PHLO, assign it to a Plivo number.

• On the Numbers page of the console, under Your Numbers, click the phone number you want to use for the PHLO.

• In the Number Configuration box, select PHLO from the Application Type drop-down.

• From the PHLO Name drop-down, select the PHLO you want to use with the number, then click Update Number.

Test

You can now send a text message to your Plivo phone number and see how the inbound text is handled.

For more information about creating a PHLO application, see the PHLO Getting Started guide. For information on components and their variables, see the PHLO Components Library.

Forward an incoming SMS/MMS message

More use cases

We illustrate more than a dozen use cases with code for both PHLO and API/XML on our documentation pages.

Using API

Install Python, Sanic, and the Plivo Python SDK

You must set up and install Python, Sanic, and Plivo’s Python SDK before you send your first SMS message.

Install Python

Download and install Python from its official site.

Install Sanic and the Plivo Python SDK

Create a project directory and change into it.

$ mkdir mypythonapp
$ cd mypythonapp

Install Sanic and the Plivo Python SDK using pip.

$ pip install sanic plivo

We recommend that you use virtualenv to manage and segregate your Python environments, instead of using sudo with your commands and overwriting dependencies.

Send your first outbound SMS/MMS message

You must have a Plivo phone number to send messages to the US or Canada; you can rent a Plivo number from Phone Numbers > Buy Numbers on the Plivo console or via the Numbers API.

Set up a Sanic server

Create a file called SendSMS.py and paste into it this code.

SMS

import plivo

client = plivo.RestClient('<auth_id>','<auth_token>')
message_created = client.messages.create(
   src='<sender_id>',
   dst='<destination_number>',
   text='Hello, from Sanic!')
print(message_created)

MMS

import plivo

client = plivo.RestClient('<auth_id>','<auth_token>')
message_created = client.messages.create(
   src='<sender_id>',
      dst='<destination_number>',
      media_ids=['801c2056-33ab-499c-80ef-58b574a462a2'],
      text='Hello, MMS from Sanic!',
      media_urls=['https://media.giphy.com/media/26gscSULUcfKU7dHq/source.gif'],
      type_='mms')
print(message_created)

Replace the auth placeholders with your authentication credentials from the Plivo console. Replace the phone number placeholders with actual phone numbers in E.164 format (for example, [phone]). In countries other than the US and Canada you can use a sender ID for the message source.

Note: We recommend that you store your credentials in the auth_id and auth_token environment variables to avoid the possibility of accidentally committing them to source control. If you do this, you can initialize the client with no arguments and Plivo will automatically fetch the values from the environment variables. You can use os.environ to store environment variables and fetch them when initializing the client.

Test

Save the file and run it.

$ python SendSMS.py

Receive your first inbound SMS/MMS message

To receive incoming messages, you must have a Plivo phone number that supports SMS; you can rent numbers from the Numbers page of the Plivo console or by using the Numbers API.

Set up a Sanic server

Create a file called receive_sms.py and paste into it this code.

SMS

import plivo
from plivo import plivoxml
from sanic import Sanic
from sanic.response import text

app = Sanic("Plivo SMS App")


@app.route("/receive_sms/", methods=["POST", "GET"])
async def receive_sms(request):
    from_number = request.values.get("From")
    to_number = request.values.get("To")
    text = request.values.get("Text")
    print("Message received - From: %s, To: %s, Text: %s" % (from_number, to_number, text))

    return "Message Received"


if __name__ == "__main__":
    app.run(host="0.0.0.0", port=8000)

MMS

import plivo
from plivo import plivoxml
from sanic import Sanic
from sanic.response import text

app = Sanic("Plivo SMS App")

@app.route("/receive_sms/", methods=["POST", "GET"])
async def receive_sms(request):
    from_number = request.values.get("From")
    to_number = request.values.get("To")
    text = request.values.get("Text")
    media_url = request.values.get("Media0")
    print("Message received - From: %s, To: %s, Text: %s, Media: %s" % (from_number, to_number, text, media_url))

    return "Message Received"

Save the file and run it.

$ python receive_sms.py

You should see your basic server application in action at http://localhost:8000/receive_sms/.

Expose your local server to the internet

To receive incoming messages, your local server must connect with Plivo API services. For that, we recommend using ngrok, which exposes local servers running behind NATs and firewalls to the public internet over secure tunnels. Using ngrok, you can set webhooks that can talk to the Plivo server.

Note: Before starting the service, add ngrok in the allowed hosts list in the settings.py file in your project.

ALLOWED_HOSTS = ['.ngrok.io']

Run ngrok on the command line, specifying the port that hosts the application on which you want to receive messages (80 in this case):

$ ./ngrok http 80

This starts the ngrok server on your local server. Ngrok will display a forwarding link that you can use as a webhook to access your local server over the public network.

Now people can send messages to your Plivo number.

Create a Plivo application to receive messages

Associate the controller you created with Plivo by creating a Plivo application. Visiting Messaging > Applications and click Add New Application. You can also use Plivo’s Application API.

Give your application a name — we called ours Receive SMS. Enter the server URL you want to use (for example https://<yourdomain>.com/receive_sms/) in the Message URL field and set the method to POST. Click Create Application to save your application.

Assign a Plivo number to your application

Navigate to the Numbers page and select the phone number you want to use for this application.

From the Application Type drop-down, select XML Application.

From the Plivo Application drop-down, select Receive SMS (the name we gave the application).

Click Update Number to save.

Test

Send a text message to the Plivo number you specified using any phone.

Reply to an incoming SMS/MMS message

To receive incoming messages, you must have a Plivo phone number that supports SMS; you can rent numbers from the Numbers page of the Plivo console or by using the Numbers API.

Set up a Sanic server

Create a file called reply_to_sms.py and paste into it this code.

import plivo
from plivo import plivoxml
from sanic import Sanic
from sanic.response import text

app = Sanic("Plivo SMS App")


@app.route("/reply_to_sms", methods=["POST", "GET"])
async def reply_to_sms(request):
    from_number = request.values.get("From")
    to_number = request.values.get("To")
    text = request.values.get("Text")
    print(
        "Message received - From: %s, To: %s, Text: %s" % (from_number, to_number, text)
    )

    # send the details to generate an XML
    response = plivoxml.ResponseElement()
    response.add(
        plivoxml.MessageElement(
            "This is an automatic response", src=to_number, dst=from_number
        )
    )
    print(response.to_string())  # Prints the XML
    # Returns the XML
    return Response(response.to_string(), mimetype="application/xml")


if __name__ == "__main__":
    app.run(host="0.0.0.0", port=8000)

If you haven’t done so already, expose your local server to the internet.

Create a Plivo application to reply to messages

Associate the controller you created with Plivo by creating a Plivo application. Visiting Messaging > Applications and click Add New Application. You can also use Plivo’s Application API.

Give your application a name — we called ours Reply Incoming SMS. Enter the server URL you want to use (for example http://<yourdomain>.com/replysms/) in the Message URL field and set the method to POST. Click Create Application to save your application.

Assign a Plivo number to your application

Navigate to the Numbers page and select the phone number you want to use for this application.
