Chat web server

This web server was created in collaboration with the social entrepreneurship Incluyo to achieve a system of attention to LGBTQ+ people in a direct way in which their privacy is prioritized.

It was created in ExpressJS with the help of the WhatsApp Business API webhook and socket.io.

This server receives the WhatsApp webhook requests directly from the Incluyo help number. These requests are processed according to the type: status or message. The data is fetched and cleaned from the request to be stored in the Supabase database and finally sends the messages to the UI client via WebSockets for real-time communication.
