A big thanks to the OAuth.io team for all of the efforts towards providing a easy to deploy solution for OAuth. I just tried to integrate the feedly sandbox key and secret (found here) in order to test the integration of said API. I have gotten only errors for the 4th time now. I am getting:
{"errorCode":400, "errorId":"sandbox-he.2015070222.2091404", "errorMessage":"unknown scope:https://sandbox.feedly.com/subscriptions"}
Is this something OAuth.io is supporting? Do they intend for the sandbox version to work? Having the sandbox version working would seem to align with the workflow for feedly apps.
