1. "Invalid Client ID" or Sign-in Error

Cause: The Client ID or Secret entered in the desktop app does not match the registered Zoom Marketplace app credentials, or the redirect URL in Zoom's marketplace settings doesn't match.

Solution:

• Open the Zoom App Marketplace and verify your app credentials under App Credentials.
• Ensure your OAuth Redirect URL and OAuth Allow List include: https://zoom-backup-callback.pages.dev/
• In Zoom BackUpz, paste the new Client ID and Client Secret, then click Sign In with Zoom (Browser).

2. Browser Did Not Automatically Redirect Back to App

Cause: Some browser security extensions or popup blockers prevent web pages from invoking custom desktop URI protocols (zoombackup://).

Solution:

• On the authorization success page in your browser, click the blue "Open Zoom Backup System" button.
• If the app still does not resume, copy the Authorization Code displayed on the webpage.
• In Zoom BackUpz, click "Having trouble with auto-redirect?", paste the code, and click Complete Sign-In with Code.

3. Downloads Failing or Stalling

Cause: Network interruption, expired download tokens from Zoom, or insufficient disk space.

Solution:

• Verify your destination drive has sufficient free storage for high-definition MP4 video files.
• Zoom BackUpz features automated chunked retry logic. If a download stalls, click Retry on the recording item.
• If your access token expired during a long backup batch, the application will refresh it automatically via the Zoom OAuth refresh token.

Does Zoom BackUpz send my video recordings to any third-party cloud?

No. Absolutely not. All cloud recording files are downloaded directly from Zoom's CDN to your host computer via encrypted HTTPS. Your video, audio, and transcript files never pass through any intermediate server operated by Zoom BackUpz or third parties.

What Zoom permissions (scopes) are required?

Zoom BackUpz requests only the minimal permissions required to archive your recordings:

• recording:read / cloud_recording:read: To list and download your cloud recordings.
• user:read: To identify your account and organize recordings by user.

The app does not request write, delete, or meeting control permissions.

How do I disconnect or remove the app?

You can revoke access at any time directly through the Zoom App Marketplace:

1. Sign into marketplace.zoom.us.
2. Click Manage > Added Apps.
3. Click Remove next to Zoom BackUpz.
