Twilio sends form variables named MediaUrl X, where X is a zero-based index. Most of these, such as the To phone number, the From phone number, and the Body of the message are available as properties of the request parameter to our action method. When Twilio calls your webhook, it sends a number of parameters about the message you just received. The URL points to a server generating TwiML instructions including the media you want to send. Viewing, saving, or manipulating the media files on incoming WhatsApp messages also involves configuring a Webhook URL.

Authentication allows you to password protect your TwiML URLs on your web server so that only you and Twilio can access them. Twilio supports HTTP Basic and Digest Authentication. Make sure you choose HTTP POST or HTTP GET to correspond to what your web application is expecting. You can set the webhook URL for incoming messages to your server in the Sandbox. Now that you have a URL for your web application's TwiML reply generating routine, you can configure your Twilio phone number to call your webhook URL whenever a new WhatsApp message comes in for you. Check out the API Reference for more details. You should receive a WhatsApp message that includes an image. If necessary, restart your server, then send a message to your WhatsApp number again. To send media in response to an incoming WhatsApp message, simply add an image URL. (We only recommend the latter for development and testing purposes and not for production deployments.) That means you need to publish your web application to a web or cloud hosting provider (of which there are many), you can host it on your own server, or you can use a service such as ngrok to expose your local development machine to the internet. Twilio can only access public servers on the Internet.
WHATSAPP XML FILE CODE
You have the code – now you need a URL you can give to Twilio. TwiML is the Twilio Markup Language, which is just to say that it's an XML document with special tags defined by Twilio to help you build your messaging and voice applications. Finally, your application sends a TwiML response to Twilio in which it specifies the instructions for Twilio to follow. This could be something like database read/writes or calling another API. When it receives this request, your application performs pre-defined logic. First, a webhook makes an HTTP request to a URI that you provide to Twilio. Webhook functionality is the same for every Twilio application. In this tutorial, we'll be setting up our web application with Flask. Django and Flask are two popular Python web development frameworks. Almost all server-side programming languages offer some framework for you to do this. To handle a webhook, you only need to build a small web application that can accept the HTTP requests. When that event occurs, Twilio makes an HTTP request (usually a POST or a GET) to the URL configured for the webhook. They are usually triggered by some event, such as receiving an SMS message or an incoming phone call. Webhooks are user-defined HTTP callbacks. If the WhatsApp session with a user expires, you must wait for an inbound message to create a new session before you can send them a media message. WhatsApp media content is currently only supported in Session Messages.
