Hello again Gianni,
Thanks again for the clarification. I have updating my application to correctly respond to webhook validation requests, but I am noticing the marketplace UI shows an error when I now trigger a validation request.
I am fairly certain my response is correct → I have tested this by running the sample application locally, and sending the same request headers/body from the request triggered via the app manager UI validation button (and verifying the response is 200 ok and the response body from the sample app matches the one produced by my production application).
I should mention that when I refresh the page, the green checkmark on the validation status shows up again.
I can send you a link to a video recording of what I am seeing.
They’re seeing 403 forbidden errors for the validation requests. Do you mind reviewing the validation process against our documentation? I don’t doubt you’ve been thorough, but this would be helpful @mokutsu
