Description/Error When using an http (NOT https) redirect url, Zoom will change the redirect_uri param to https and then fail to redirect. How To Reproduce Steps to reproduce the behavior: Setup an application with an http redirect e.g. http://localhost:3000/_/zoom_redirect Make sure the user is logged out from Zoom Start the Zoom Oauth Flow by redirecting the user to https://zoom.us/oauth/authorize?client_id=XXX&redirect_uri=http%3A%2F%2Flocalhost%3A3000%2F_%2Fzoom_redirect&response_type=code&state=YYY Login to Zoom with Google. Get an Zoom error page (NB https): Invalid redirect: https://localhost:3000/_/zoom_redirect (4,700) This is hopefully only an issue for local development but is still pretty annoying!

Hey @ryan, Can you try this to resolve the issue: [image] Zoom Application Wrong redirect App Marketplace Hey @subhan, This issue only happens with localhost urls. To solve this you could use https://ngrok.com/ to turn your localhost server into a free server with a url, and replace the localhost redirect url with the ngrok url. Instead of http://localhost:8080/api/v1/zoom/complete-oauth it would be https://d4c4477b.ngrok.io/api/v1/zoom/complete-oauth This way you can still develop and test locally and have your redirect url work! Let me know if this helps! Let me know if this works! Thanks, Tommy

It definitely does work, but we’ve had some issues running all of our traffic over ngrok so we’re reserving it just for webhooks. Self-signed certs would also be a solution but a bit of a hassle to set up… For the time being we’ll put up with the minor annoyance and we’ll look forward to a bug fix.

Hey @ryan, I was able to reproduce the error. This only happens when signing in with Google. Like you said, it changes http to https. We will work on fixing this. Thanks again for posting. JIRA: ZOOM-121664 Thanks, Tommy

Hey @tommy, This still seems to be an issue. Our redirect url is being changed from http://localhost to https://localhost. Any updates on this?

Hey @edward, No updates, I would suggest using Ngrok. [image] Zoom Application Wrong redirect App Marketplace Hey @subhan, This issue only happens with localhost urls.

Hey @tommy, Yes, I saw that suggestion. Unfortunately, we deal with a large amount of traffic, and therefore using ngrok is not an ideal solution for us. Edward

Hey @edward, we are working to make localhost redirect urls work. Although, I was able to install the app successfully using http://localhost installing via the “Local Test” page and not using Google SSO. Are you signing in with Google? Thanks, Tommy

Hey @tommy, What do you mean by “Local Test”? Re: using Google SSO- I am observing this as an issue for both Google SSO and for Zoom account logins. Thanks, Edward

Hey @edward, “Local Test” as in: [Screen Shot 2020-01-23 at 5.11.51 PM] Oh I see. The issue does not happen if you are already logged in to Zoom. In the meantime, we are working on fixing the issue. Thanks, Tommy

Hi, I’m getting the same issue on my side. Do you have any update ? Also, if my redirect url has 2 parameters, the last one is always deleted : http://localhost/example.html?param1=blabla&param2=toto becomes https://localhost/example.html?param1=blabla&code=zoom_code
