Getting Invalid request : Redirect URI mismatch error

Description I’m getting a Redirect URI mismatch error when trying to get an access token after getting the code. It’s probably because I misunderstood how redirect URI works. I tried the following: Exact same URI as in app settings Same URI that I provided in oauth/authorize call when getting the code I’m getting the same error every time. Error { “reason”: “Invalid request : Redirect URI mismatch.”, “error”: “invalid_request” } Which App Type (OAuth / Chatbot / JWT / Webhook)? OAut…

OAuth with zoom - redirect uri is not used for redirect

Hi, I’m currently working on an OAuth application with Zoom. Here the error occurs that the redirect Uri I specified is not accepted, but I am sent back to the zoom page. My Request URL: https://zoom.us/oauth/authorize?client_id=XXX&response_type=code&redirect_uri=http://localhost:8080/vccfg/login/oauth2/code/zoom&state=XXX Location I get send to after the request: http://zoom.us/vccfg/login/oauth2/code/zoom?code=XXX Screenshot from my browser: [Zoom%20OAuth%20Redirect%20Browser%20Screensho…

Hey @akhilesh,

Please checkout my post here:

'Invalid request : Redirect URI mismatch.' despite using ngrok

Hey @Nad, Let me know if this helps explain things: The Redirect URI needs to be the same URI from the authorization (install URL) through to the Get Access Token request. So with these URLs set: [Screen Shot 2020-07-23 at 10.02.37 AM] When I go to install the app from the “Activation” page, it defaults the redirect URI to the one specified in the “Redirect URL for OAuth” input: https://zoom.us/oauth/authorize?response_type=code&client_id=ztmR8sxaSBGZ66b5laR7Ag&redirect_uri=https://zoom.u…

If that does not help, please share your the redirect url you are using so I can help debug.

Thanks,
Tommy

Hi @akhilesh,

Can you also please whitelist the full Redirect URL as well (…/services/apexrest…) in addition to the main domain, and let me know if you’re still experiencing the error?

Thanks,
Will

Hey @akhilesh,

I’m getting a 500 error when I try to access your redirect URL. Can you confirm this is publicly accessible and isn’t experiencing any internal server errors?

Thanks,
Will

Hey all figured this out with the help of Will, we need to make sure redirect url,white list has “slash” in the end like below in market place app.

Example:
“https://zoom.us/”

=========================================================

Also make sure if you are using state in your URL while getting OAuth Code use the same state in getting access token as well.

For example:

if you are using some thing like below to get Authorization Code

https://zoom.us/oauth/authorize’+’?response_type=code’+’&client_id=xxxxxxxxxxxxxx’+’&redirect_uri=‘https://zoom.us/’+’?state=’+‘test’

Make Sure you do the same state while calling access token end point

https://zoom.us/oauth/token’+’?grant_type=authorization_code’+’&code=’+OAuthCode+’&redirect_uri=’+‘https://zoom.us/’+’?state=’+'test’

I wish the documentation is a little clear on state stuff as well

Thanks!
