Webhook replying 200, but no data in debug node

I have a workflow with only two nodes. A webhook trigger and a debug node.
The sender of the data ( SendGrid) says they are receiving “200” responses when they test the endpoint, but I am not seeing any data in the debug node.

Is there something I’m overlooking ?

I can think of three possibilities:

  1. The webhook URL they are hitting is not the same one you are trying to trigger the workflow off of.
  2. There could be a typo in their webhook URL; we would return a 200 for such a request.
  3. The Debug Node is muted, or its level has been disabled in the debug log.

Its an “inbound email parse”. For some reason, sending test emails from my domain do not work ( a sendgrid thing). But when sent from outside domains it works.
