Hi,
I am attempting to integrate OAuth 2.0 on an app running on a private server. I am trying to set the callback URL as an insecure http address but the “Save changes” button is grayed out. We have an existing app created ~3 years ago, integrated with OAuth 2.0 using an insecure http callback URL.
Is there a work around for this that I am unware of, or was the requirement for the callback URL to be a secure https address added sometime since then?
eg.
Thanks in advance for any help!
