Bug with http:// redirect

[ryan]

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:

1. Setup an application with an http redirect e.g. http://localhost:3000/_/zoom_redirect
2. Make sure the user is logged out from Zoom
3. 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
4. Login to Zoom with Google.
5. 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:

Zoom Application Wrong redirect

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?

[tommy (Tommy Gaessler)]

Hey @edward,

No updates, I would suggest using Ngrok.

Zoom Application Wrong redirect

I will keep you updated on when we are releasing a fix.

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.

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

[edward]

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

[tommy (Tommy Gaessler)]

Hey @edward,

“Local Test” as in:

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

[tommy (Tommy Gaessler)]

Hey @martin, thanks for posting and using Zoom!

No updates on this, we are still working on the issue.

As for the query params, that is intended functionality. Here is the proper way to add query params:

Client ID not being recognised

Hey @rich, Here is whats happening, in your app dashboard you have https://dev.thetherapy.space/_ajax/?ajax_response=oauth&model=zoom&componentID=external_connections as your redirect url. Then when you go to authorize your app: https://zoom.us/oauth/token?grant_type=authorization_code&code=6Y6x0lVGDt_XXXMxyKRRhOz1obX4Z0I6g&redirect_uri=https://dev.thetherapy.space/_ajax/?ajax_response=oauth&model=zoom&componentID=external_connections Zoom handles your &model=zoom&componentID=external_conn…

Thanks,

I am having the same issue. Installing required certificates to use https seems quite tedious on a local development environment. Is there a way to redirect locally with out using https? Ngrock seems like a proprietary solution- is there an external solution that is not proprietary.

[michael.zoom (Michael)]

Hi @aurena, without the creation of your own redirect to localhost, using ngrok is our suggested local testing solution. We require all redirect URLs to be HTTPS.
