This repository contains the server-side web application required to run the Twilio Programmable Voice iOS SDK Quickstart and Android SDK Quickstart mobile sample apps.

Looking for the Quickstart mobile app?

• Follow the iOS full quickstart tutorial here or Android full quickstart tutorial here.

Create a configuration file for your application:

cp .env.example .env

Edit .env with the three configuration parameters we gathered from above.

Next, we need to install our dependencies from npm:

npm install

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

node .

Visit http://localhost:3000 to ensure the server is running.

This web application needs to be accessbile on the public internet in order to receive webhook requests from Twilio. Ngrok is a great options for getting this done quickly.

Once you have the application running locally, in a separate terminal window, make your server available to the public internet with the following:

    ngrok http 3000

You should see a dynamically generated public Ngrok URL in the command window. Ngrok will now tunnel all HTTP traffic directed at this URL to your local machine at port 3000.

Test your app by opening the {YOUR_SERVER_URL}/accessToken endpoint in your browser. Use the publicly accessible domain on ngrok. You should see a long string. This is an Access Token. You can examine its contents by pasting it into a JWT tool like jwt.io.
