I am wondering if you figured this out? I have been trying to make a Webhook for 2 days using Pipelines. I get the same errors you do. I have gone through all the documentation, formatted the headers, have the access token, etc.. but still error regarding authorization. I am certain it has something to do with the format of the request that is being sent from Pipelines but I cannot figure out how to see what the final request being sent looks like -
any further discoveries you make would be extremely helpful - thank you
