I have an Azure Function that should responds to a SharePoint webhook that I can't get to validate.
1: Is a screen shot of my function with a test showing that it is returning a validation token when one is passed
2: See here a postman trace showing that it fails to validate. There are no log entries in the Azure Function. I have validated that the function code is the default code and I can run function from post man 3: is proof that the function returns a validationToken when passed
4: is the webhook working when the service URL is an anonymous webapi method
What am I missing? I had this working on a developer tenant a week ago and now after GA I can't get it to work anywhere.
