Google Classroom

Use this guide to configure customer-owned Google OAuth for Google Classroom and troubleshoot consent, scope, or token failures.

Configure custom Google OAuth for Google Classroom

Follow the Google Apps credential setup guide. For a step-by-step guide to creating and configuring Google OAuth credentials with Composio, see How to create OAuth2 credentials for Google Apps.

Enable the Google Classroom API in the credential's Cloud project. When using custom credentials, enable the Google Classroom API in the Google Cloud project that owns the credentials. After enabling it under APIs & Services, wait a few minutes and retry.

Set the consent-screen name and current redirect URL. Google Classroom currently uses customer-owned OAuth credentials. Configure the app name and branding in the Google Cloud project that owns those credentials, and use the redirect URL shown by Composio's current auth-config flow.

Troubleshoot Google Classroom OAuth and tool calls

Remove unverified scopes when Google reports “App is blocked.” This error usually means the OAuth client is requesting scopes that Google has not verified for that client. Remove additional scopes beyond the defaults, or use a custom OAuth app and submit the scopes for verification.

Validate scopes when OAuth returns Error 400: invalid_scope. Verify the requested scopes and their formatting against the Google OAuth scopes documentation.

Reconnect when tool calls return 401. A 401 usually means the access token is no longer valid. The user may have revoked access, changed password or two-factor settings, been affected by an administrator policy, or exceeded Google's refresh-token limit. Re-authenticate the connected account and retry.
