WhatsApp API Bot (In Progress)

WhatsApp API Bot with a Flask server, launched using ngrok.

The server can currently handle:

• Initial webhook configuration and token verification with Meta.
• Incoming messages - server marks the incoming message as "read" and responds with a default greeting text message.
• Prints status updates for sent messages (e.g. "delivered", "read" etc.)

The app requires the following variables to be stored inside the environment for it to work:

• WHATSAPP_TOKEN - (temporary) Meta access token (can be found inside the "API Set Up" section on the Meta for Developers website).
• VERIFY_TOKEN - your own verification token to be used for the webhook configuration (can be any string).
• GRAPH_BASE_API - base API url (currently version 17 is used - https://graph.facebook.com/v17.0/).
• PHONE_NUMBER_ID - your sender WhatsApp phone number id.
