Hey!
Looks like your webhook is working just fine
You’re getting a 200 Success and the payload is correct, so Facebook is sending the data.
So now the problem is likely on the n8n side:
Try this checklist:
Webhook URL
Make sure the webhook URL used in the Facebook app matches exactly what n8n is expecting (no trailing slashes, no wrong port, etc).
n8n Webhook Trigger is Running
The workflow must be active (not just in edit mode) for the webhook to catch incoming data.
Use a Webhook Node (as test)
Just to confirm that the data is arriving at all, create a simple test workflow like this:
Webhook node (manual response enabled)
Respond with the full payload
Check Execution Logs
If this works, you’ll know the issue is just with the Facebook Lead Ads Trigger node logic.
Check your n8n logs or webhook history
You might find that the trigger did run, but an error happened downstream.
Let me know if you want a minimal working workflow to test this — I’ve got one ready.
You should also validate you are using the “test” webhook URL when workflow is disabled and the “production” webhook when it is.
Common issues#
Here are some common errors and issues with the Facebook Lead Ads Trigger node and steps to resolve or troubleshoot them.Workflow only works in testing or production#
Facebook Lead Ads only allows you to register a single webhook per app. This means that every time you switch from using the testing URL to the production URL (and vice versa), Facebook Lead Ads overwrites the registered webhook URL.
You may have trouble with this if you try to test a workflow that’s also active in production. Facebook Lead Ads will only send events to one of the two webhook URLs, so the other will never receive event notifications.
From:
test not works when active after few minuts it seems all works
That worked? Great!
If you could mark my message as the solution that would be appreciated
