Audit calendar reservations before sending confirmation
The agent waits for a calendar event ID before confirming, then a nightly check compares claimed reservations with actual calendar entries.
- What they did
- One builder configured their booking agent to hold off on a confirmation message until the calendar system produces an event ID. If that identifier never arrives, the agent tells the customer the reservation is still pending and marks it for manual review. They also keep a nightly reconciliation process that reviews each booking the agent said was created and checks it against the calendar, with extra attention on stored time, timezone, attendees, and idempotency keys to reduce duplicate retries.
- How it went
- This changes the main failure pattern from a wrong confirmation to no confirmation at all. Problems can still slip through when the calendar entry is partly wrong, such as an invitation not being sent or the event landing at an incorrect time.
- Tips
- A commenter said a new client can often start with a single reconciliation query for each action type, and that booking into a calendar is quick. Make sure the audit step checks the data fields you care about, not just whether an event exists.
Try it yourself with n8n
Build an n8n workflow for [calendar system] that creates appointments and sends a confirmation to the customer only after the calendar API gives back an event ID. If no ID is returned, tell the customer the request is still pending and flag it for review. Add a nightly check that compares every booking the agent claimed to create with the calendar records and sends any mismatches to [email or Slack]. Stop and ask for my approval before any step that would send, submit, delete, or charge. Test it first with a fake appointment and report what happened.
Fill in the [brackets]. Agents can make mistakes, so review anything before it is sent, paid or deleted.
