How to receive user activity notifications via whatsapp? it’s possible?
I think you would need to implement the logic yourself, by sending API calls to WhatsApp API.
Here are the docs for this: WhatsApp Business Platform - Documentation - Meta for Developers
Thank you very much for the answer, another question, and how would I work with simple notifications in the app itself?
Do you mean in a mobile or web app?
Then you would need to use WhatsApp API to trigger notifications I think!
