Hey there, hope someone can lend me a hand with this.
I am currently implementing a basic OAuth interaction from an app in local development with Trello, i made most of it work, the request token process is done properly, and the Trello page requesting for app access appears properly, but i get a problem with the return url because i tried using an Out-Of-Bounds oauth request.
Can you tell me if it is possible to do said OOB request or if it is simply not allowed?
I had to add a url in the power-up app for the iframe and for the allowed origin, but since i am working in local, i have no intention to create a temporary server with said allowed origin.
