**Description**  
I’m trying to test Zoom OAuth locally but I get an Invalid redirect error. Invalid redirect: [https://fceca8f4.ngrok.io/auth/redirect](https://fceca8f4.ngrok.io/auth/redirect)

**Error**  
Error: Invalid redirect: [https://fceca8f4.ngrok.io/auth/redirect](https://fceca8f4.ngrok.io/auth/redirect)

2. Convert the localhost:8080 to ngrok.
3. Set the redirect URL to `https://fceca8f4.ngrok.io/auth/redirect`
4. See the error: `Invalid redirect: https://fceca8f4.ngrok.io/auth/redirect`

Hey @bimal, thanks for posting and using Zoom!

What url do you have as your whitelist URL?

Also double check you have the same redirect URL in the Marketplace dashboard, as in your [OAuth request](https://marketplace.zoom.us/docs/guides/authorization/oauth/oauth-with-zoom#step-2-request-token).

Thanks,  
Tommy
