Issue with Zoom OAuth Authentication for Non-App Creators

API and Webhooks Authentication
1

Hello,

I’m integrating Zoom OAuth authentication into my web app, but I’m encountering an issue where only the app creator (myself) can authenticate successfully. The goal is to allow any Zoom user to authenticate and access the app.

Here’s the flow I’m implementing:

  1. User selects Zoom authentication on the web app.
  2. User is redirected to the Zoom login page.
  3. After login, Zoom redirects back to the web app with an authorization code.
  4. The web app sends the code to the backend.
  5. The backend exchanges the code for an access token via Zoom’s OAuth API.
  6. The backend then requests the user’s email and username using the access token.
  7. The backend confirms authentication to the frontend via a session token.

I’ve created a “User-managed” app in the Zoom Marketplace, added the scope for reading user information, and whitelisted the redirect URL. However, authentication only works for my Zoom account (the app creator) and fails for other users.

Am I missing a configuration step to allow any Zoom account to authenticate with my app? Any advice on making the app accessible to all users would be greatly appreciated.

Thank you!
