调用Google Calendar API Events: move接口出现404/403错误求助

Let’s break down these two common issues with the Events: move endpoint and walk through practical fixes for each scenario.

404 Error When Moving Between @gmail.com Accounts #

A 404 typically means the API can’t locate one of the core resources involved (either the source event or target calendar). Here’s what to check step by step:

• Double-check your resource IDs
  Confirm the eventId of the source event is valid by calling the events.get endpoint to verify it still exists in the source calendar. For the target Gmail account’s default calendar, use the full target email address as the destination parameter (note: "primary" refers only to the authorized user’s primary calendar, not the target account’s).
• Ensure access to the target calendar
  The authorized user (or service account) making the API call needs at least editor-level access to the target Gmail calendar. Ask the target account owner to share their calendar with your authorized identity with edit permissions—if the calendar isn’t shared, the API can’t locate it, triggering a 404.
• Rule out deleted or already-moved events
  Make sure the source event hasn’t been deleted, archived, or moved to another calendar before you attempt the move call.

403 Error When Moving Between @.com Accounts #

403 errors are almost always permission-related, and with Google Workspace (formerly G Suite) accounts, organizational policies often play a key role. Try these fixes:

• Check Workspace admin policies
  Reach out to your company’s Workspace administrator to confirm:
  • There’s no organizational policy blocking cross-user event moves within the domain.
  • Domain-wide sharing restrictions aren’t preventing calendar access between the source and target accounts.
• Verify authorization scopes
  If using a service account, ensure you’ve requested the correct API scopes. For moving events, you’ll need at minimum https://www.googleapis.com/auth/calendar.events (or the broader https://www.googleapis.com/auth/calendar scope). Avoid over-restricted scopes unless absolutely necessary.
• Confirm target calendar permissions
  Even within the same domain, many accounts have private calendars that don’t allow external edits by default. The authorized user needs edit access to the target @.com calendar—ask the target account owner to share their calendar with your authorized identity with edit rights.
• Check event ownership restrictions
  Some Workspace setups prevent moving events owned by another user. If the source event is owned by someone else in the domain, ensure the authorized user has permission to modify or move that event (ask the event owner to grant edit access).
