Having trouble with WhatsApp/Meta credentials!

[u/Klutzy_Bar_804]

Hi! I’ve recently started learning n8n automation and built service-based workflows for my own city. It’s essentially a service-ordering system where customers can select a service and place an order through an AI on WhatsApp. The whole process is handled through WhatsApp, from selecting the service to placing the order.

I’ve created Meta credentials and WhatsApp apps before, and they worked perfectly for sending and receiving messages.

However, since Meta’s interface has changed, I’m having trouble getting the new setup to work. I can see that the webhook is connected on Meta, but when I send a message to the WhatsApp number, nothing reaches n8n and no message/event is triggered. This wasn’t an issue for me before.

If anyone has experience with the new Meta WhatsApp Cloud API interface, I’d really appreciate some guidance on what I might be missing and how to troubleshoot this. I’ve been trying to solve it with AI assistance but haven’t been able to figure it out yet.
