Hey @baserow_bln,
That is a bit unexpected, I have used both the manual webhook and the node with self hosted and hosted versions of Baserow.
There isn’t really any validation that happens, here is an earlier post I made about manually setting up the webhook.
When you use the node does it register the webhook ok and when the request fails does the node get triggered?
Is there anything special with the n8n install maybe queue mode? Can you also confirm the versions of n8n and Baserow, I can do some more testing tomorrow to see if I can spot anything odd.
As a test maybe pointing the webhook in Baserow to webhook.site will show something.
