I currently have a Supplier for whom we can set a postback URL. In order to test this URL they can send out a test message. The thing is they send out a webhook with Content-Type: Application/json, but with a completely empty body not even {}. The AP Webhook returns a 400 error as it expect a body to be present.
We requested them to add the {} in order to solve this but they are not doing so. Would this be something you could allow in the Webhook so it would be even more friendlier?
I have test with other platforms like the Indian green P and there is works.
Looking forward for your feedback.
