I need some help to send customer notifications via API. I am receiving a notification from an external service everytime our customers get paid. I would like to send customers a WhatsApp notification about payments they received, incl. the amount.
I have done this succesfully with https://api.manychat.com/fb/sending/sendContent for Instagram notifications, but I can’t seem to make it work for WhatsApp notifications. I also tried to solve this with templates, but I can’t trigger templates from external APIs.
Does anyone know how to send a custom message to a WhatsApp contact via API?
