This sample project demonstrates how to use Twilio APIs in a Python web application. Once the app is up and running, check out the home page to see which demos you can run. You'll find examples for IP Messaging, Video, Sync, and more.

Let's get started!

Configure the sample application

To run the application, you'll need to gather your Twilio account credentials and configure them in a file named .env. To create this file from an example template, do the following in your Terminal.

cp .env.example .env

Open .env in your favorite text editor and configure the following values.

Configure account information

Every sample in the demo requires some basic credentials from your Twilio account. Configure these first.

Config Value	Description
`TWILIO_ACCOUNT_SID`	Your primary Twilio account identifier - find this in the console here.
`TWILIO_API_KEY`	Used to authenticate - generate one here.
`TWILIO_API_SECRET`	Used to authenticate - just like the above, you'll get one here.

A Note on API Keys

When you generate an API key pair at the URLs above, your API Secret will only be shown once - make sure to save this information in a secure location, or possibly your ~/.bash_profile.

Configure product-specific settings

Depending on which demos you'd like to run, you'll need to configure a few more values in your .env file.

Config Value	Product Demo	Description
`TWILIO_IPM_SERVICE_SID`	IP Messaging	Like a database for your IP Messaging data - generate one in the console here
`TWILIO_CONFIGURATION_SID`	Video	Identifier for a set of config properties for your video application - find yours here
`TWILIO_SYNC_SERVICE_SID`	Sync (Preview)	Like a database for your Sync data - generate one with the curl command below.
`TWILIO_NOTIFICATION_SERVICE_SID`	Notify (Preview)	You will need to create a Notify service - generate one here
`TWILIO_APN_CREDENTIAL_SID`	Notify (Preview)	Adds iOS notification ability to your app - generate one here. You'll need to provision your APN push credentials to generate this. See this guide on how to do that. (Optional)
`TWILIO_GCM_CREDENTIAL_SID`	Notify (Preview)	Adds Android/GCM notification ability to your app - generate one here. You'll need to provision your GCM push credentials to generate this. See this guide on how to do that (Optional)

Temporary: Generating a Sync Service Instance

During the Sync developer preview, you will need to generate Sync service instances via API until the Console GUI is available. Using the API key pair you generated above, generate a service instance via REST API with this curl command:

curl -X POST https://preview.twilio.com/Sync/Services \
 -d 'FriendlyName=MySyncServiceInstance' \
 -u 'SKXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX:your_api_secret'

Run the sample application

This application uses the lightweight Flask Framework.

We need to set up your Python environment. Install virtualenv via pip:

pip install virtualenv

Next, we need to install our dependencies:

virtualenv venv
source venv/bin/activate
pip install -r requirements.txt

Now we should be all set! Run the application using the python command.

python app.py

Your application should now be running at http://localhost:5000. When you're finished, deactivate your virtual environment using deactivate.

Running the SDK Starter Kit with ngrok

If you are going to connect to this SDK Starter Kit with a mobile app (and you should try it out!), your phone won't be able to access localhost directly. You'll need to create a publicly accessible URL using a tool like ngrok to send HTTP/HTTPS traffic to a server running on your localhost. Use HTTPS to make web connections that retrieve a Twilio access token.

ngrok http 5000
