The issue is you’re hitting Meta’s API limitation - only one WhatsApp trigger can be active per Facebook App. Try these steps:

1. Check if you have any other workflows using WhatsApp triggers with the same app ID

2. Make sure your webhook URL in Meta Developer Portal matches exactly what’s in your n8n trigger

3. Verify your app is published in Meta’s dashboard (not just in development mode)

One thing to double-check here: the “Listening for test event” state in n8n does not register the webhook with Meta by itself.

Even if the test number receives messages, the WhatsApp trigger will only fire if the webhook URL from the n8n node is correctly registered and verified in Meta Developers → WhatsApp → Configuration, with the messages event subscribed.

Also make sure you’re testing with a different phone number than the WhatsApp Business number itself — messages sent from the same number usually don’t trigger events.
