Agent pitfalls & tips
- Each Workspace API (Gmail, Calendar, Drive, Admin) has different scopes — request minimal scopes.
- Domain-wide delegation requires Google Workspace admin to authorize the service account.
- Use fields parameter to select specific response fields (same as opt_fields).
- Gmail API uses base64url encoding for message bodies — not plain base64.
- Admin SDK requires super admin or delegated admin privileges.
