How to Receive Images on WhatsApp using Django and Twilio

The tutorial explains how to receive images sent by users on WhatsApp using Django and Twilio. To start, the user needs to create a new Django project and install the necessary dependencies, including Twilio's Python Helper library, requests package, and Pyngrok. The user then sets up a WhatsApp sandbox account and connects their smartphone to it. Next, they configure the Django project to use ngrok to make the local server accessible over the internet. A webhook is created using Twilio's concept of webhooks, which allows the application to perform custom actions in response to external events such as receiving a message from a user on WhatsApp. The user updates the logic inside the message endpoint to extract information about the incoming message and saves the image locally. Finally, they send a response back to the user through WhatsApp using TwiML. To complete the setup, the user configures the WhatsApp webhook in the Twilio console and tests it by sending a message to the sandbox number.
