Invalid redirect url on published app (errorCode: 4700)

Zoom Apps Configuration

We are working with a Laravel Framework backend and using OAuth 2.0 for authentication with our Zoom Marketplace app.

Description

We are facing an issue with our published app on the Zoom Marketplace:
:link: App Marketplace

When attempting to install the app using the Authorization URL provided in the Zoom app configuration, we are receiving an error that prevents installation for all users.

Error?

Invalid redirect: https://meetings.complilyapps.com/oauth_token (4,700)

This is the exact URL configured in our app settings under OAuth Redirect URL for Production:

https://meetings.complilyapps.com/oauth_token

This was previously working fine, and we have not made any changes to this configuration, as public apps do not allow redirect URL updates after submission. The same redirect URL is also present and correct in the OAuth Allow Lists section.

Troubleshooting Routes

  • Double-checked Zoom App Configuration for redirect URLs (both in production and development).
  • Verified the redirect URL matches exactly and is still correctly whitelisted.
  • Confirmed that no server-side changes have been made to the callback endpoint.

How To Reproduce

  1. Go to: App Marketplace
  2. Click “Install” and proceed with Zoom authorization.
  3. After login/authorization, the app attempts to redirect to:
    https://meetings.complilyapps.com/oauth_token
  4. Error page displays:
    Invalid redirect: https://meetings.complilyapps.com/oauth_token (4,700)

Hi @Joe11
Thanks for reaching out to us and welcome to the Zoom Developer Forum.
Have you mande any changes to your redirect URL after the app was published? Please note that if you make changes to a published app, you have to submit the app for an Update review to the Marketplace team and once the app is reviewed by the team, changes will be reflected in production
