Book customers and verify bookings against the calendar
A booking agent confirms a customer only after the calendar returns an event ID, and a nightly job diffs claimed bookings against the calendar. ·
Done with a custom-built or unnamed agent
- What they did
- One builder said the agent is not allowed to send a booking confirmation until the calendar call returns an event ID; otherwise it tells the customer it will confirm shortly and flags the case. They also run a nightly job that reads every booking the agent claimed and diffs it against the calendar, with comments adding that read-backs should verify the stored time, timezone, attendees, and use idempotency keys to avoid duplicate retries.
- How it went
- The reported benefit is that the main failure mode becomes no confirmation instead of a false one. What still slips through are partial or wrong-data successes, such as an invite not being sent or an event created for the wrong time.
- Worth knowing
- For a new client, one commenter said setup is basically one reconciliation query per action type, with calendar booking described as quick.
Try it yourself with n8n
Build an n8n workflow where a booking agent confirms a customer's appointment only after [calendar, e.g. Google Calendar] returns an event ID, and otherwise tells the customer it failed. Add a nightly job that compares all bookings the agent claimed against actual calendar events and sends me a list of mismatches at [email or Slack]. Test it with a fake booking and show me the results before going live.
