[Critical, Again] OAuth API Redirect URL changes http:// to https://

This issue, originally resolved on September 10th, has reappeared, causing critical authentication failures where the return URL does not reflect the provided return URL. The protocol is changed from http to https.

Hi @edu_dev4,

Are you still using HTTP in your redirect URL? Per Tommy’s note in the previous thread, you will need to use HTTPS to avoid issues. This is denoted in our documentation here:

The Development app credentials have always supported http. We rely on this for our developers in their local environments and in our QA environments. These are the URLs that are broken as of today.

Hey @edu_dev4,

I understand the challenge this presents and have reached out to our team to see if there have been any recent changes. I’ll let you know what I find as soon as I have an update (ZOOM-191046)

That being said, we do advise you to use HTTPS, per our documentation, even if HTTP might have worked in the past.

Thanks,
Will
