Can't register a webhook: Required parameter missing or invalid
Hi everyone, first time poster here. I've got a lot working with the API with no problems, but I need to register a webhook, and keep getting the "Required parameter missing or invalid" error. I've followed all of the instructions, but maybe I've missed something.
Headers: Content-Type: application/json
(Body content type application/json)
I can validate that the token is good, as if I change anything there I first get the error of invalid token, so it's something with a missing parameter...buy I have NO idea what I am missing. I googled around here and stackoverflow and have found no substantive answers. Any clues on what's missing??
