**Description** I’ve read multiple support issues pertaining to the `invalid redirect_uri` error that appears when using localhost. The suggested workaround is to use an Ngrok URL and that should solve the problem. **Error** When I set Ngrok as the callback URL in the credentials, Zoom tells me Invalid redirect: [https://837dd851.ngrok.io/users/auth/zoom/callback](https://837dd851.ngrok.io/users/auth/zoom/callback) (4,700)" **Which App Type (OAuth / Chatbot / JWT / Webhook)?** OAuth **Which Endpoint/s?** /authorize **How To Reproduce (If applicable)** Steps to reproduce the behavior: 1. Visit the app credentials page 2. Enter my NGrok URL as the Redirect URL 3. Visit OAuth URL with the new redirect\_uri passed as an argument Receives an error. **Screenshots (If applicable)** ![image](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/2X/5/500d0225be7a9b837cba107290f17f2e0ecdb104.png) The error can be seen here: [https://imgur.com/aypXlIj](https://imgur.com/aypXlIj) **NOTE** By changing the redirect URI again I don’t get the same error, however once I’m redirected back to my application, I continue to receive the error `{"reason":"Invalid request : Redirect URI mismatch.","error":"invalid_request"}` ---

Hey @nickoneill, thanks for posting and using Zoom! What value do you have in the URL whitelist field? Make sure it is the same domain as the Redirect URL. Thanks, Tommy ---

How did you get this to work? I have the same issue as you and am using the same URL in the whitelist field as I am for my Redirect URL ---

Hi @jam869 the ngrok URL (and the callback paths) will be unique to your application. Have you added your own Redirect URL to the whitelist? ---
