Whether I add ‘Access-Control-Allow-Origin’ : ‘*’ in the response headers of the webhook node or not doesn’t change anything : I always get the CORS error.
It’s the server itself that is responding with CORS error. Not the webhook. It’s not even accessing the webhook from what I see. Otherwise I’d get a response with HTTP 200 corresponding to the webhook response code/
Do you have a working example where you can call the webhook with a POST request from another public domain in the browser ? I didn’t find any.
