CHATBOTS
Self-Service Reschedule Webhook with Live Slot API
Powers a customer-facing reschedule page: a webhook from your portal triggers a free/busy lookup on the shared calendar, returns conflict-free slots for the customer to choose.
How it runs
The automated pipeline, trigger to output.
- TriggerReschedule page posts to webhookHTTP webhook
- ActionLoad booking and duration from PostgresPostgres
- ActionReturn conflict-free slots from calendarGoogle Calendar
- LogicRe-validate chosen slot still open
- ActionCommit rebook and update PostgresGoogle Calendar
- OutputNotify team of change in SlackSlack
What it does
Backs a "manage my appointment" button on your own site. When a customer opens the reschedule page, your portal posts to a webhook; the bot returns live, conflict-free slots from the shared Google Calendar. The customer's selection commits the rebook instantly and the team gets a Slack heads-up.
When to use it
When you want reschedule self-service inside your product or booking page rather than over chat or email, and you need the slots shown to be accurate to the second so two customers can't grab the same opening.
How it works
- 1An HTTP webhook from your reschedule page fires with the booking reference.
- 2The bot loads the booking and its duration from Postgres.
- 3It reads current free/busy from the shared Google Calendar and returns conflict-free slots to the page for the customer to pick.
- 4A logic step validates the chosen slot is still open at commit time to prevent a double-book race.
- 5It moves the Google Calendar event and updates the Postgres booking record.
- 6It posts a notification to the team's Slack channel summarizing the change.
