Hello everyone. Please, I need your help. I’m creating a WhatsApp AI agent and I’m using the Meta app and n8n. I created an app from Facebook Developers and connected it to n8n via the WhatsApp trigger node.
The problem is, when I send a test message, the trigger node doesn’t activate in my n8n instance. I asked for help on GPT Chat, and they told me to configure the callback URL with a webhook in n8n. I copied the webhook from the n8n node, pasted it into the app (callback URL), and then set a token, but I’m getting an error message.
I’ve changed my business manager, but the problem persists. Please help me solve this problem.
