Microsoft OneNote

OneNote uses a customer-owned Microsoft OAuth app

The current onenote toolkit supports OAuth2 and requires a client ID and client secret from a Microsoft Entra app registration. Enter the app's Application (client) ID and the secret value, not the secret's identifier. Register the exact redirect URI shown by the current Composio auth-config flow.

Choose the least-privileged delegated Microsoft Graph permissions that cover the intended OneNote actions. Common permissions include Notes.Read, Notes.Create, Notes.ReadWrite, and the corresponding *.All permissions for notebooks available through groups or sites. Include offline_access when the connection needs a refresh token. Microsoft documents the permission set in its Graph permissions reference.

Tenant policy or higher-privilege permissions can require administrator consent. Follow the shared Microsoft OAuth guidance and create a fresh connection after changing the app's permissions.
