When Calendly and Google Calendar operate independently, scheduling conflicts often arise due to missed updates. For instance, if a meeting is canceled in Calendly, that change may not reflect in Google Calendar, leading to double bookings. The sales team, relying on accurate calendar entries, spends excessive time manually checking and reconciling schedules, which detracts from their productivity and can result in lost opportunities.

Top Ways to Automate Calendly & Google Calendar

  • Automatic Event Syncing: Instantly sync all scheduled events from Calendly to Google Calendar, ensuring that your availability is always up-to-date and preventing double bookings.
  • Real-Time Notifications: Receive immediate alerts for new appointments and changes, allowing you to stay informed and manage your time effectively without manual checks.
  • Streamlined Rescheduling: Effortlessly update appointments across both platforms with a single action, reducing the risk of errors and enhancing client satisfaction through clear communication.

How to Build the Calendly → Google Calendar Sync

  1. In your Calendly account, navigate to the 'Integrations' section and set up a Standard Webhook. Use the endpoint https://your-webhook-url.com/callback to listen for the event.scheduled and event.canceled triggers.
  2. For the event.scheduled trigger, extract the payload data, specifically the event.start_time, event.end_time, and event.invitee.email.
  3. Next, configure your server to handle the incoming webhook data. Upon receiving a scheduled event, construct a POST request to Google Calendar's API endpoint https://www.googleapis.com/calendar/v3/calendars/primary/events.
  4. In the POST request, include a JSON body with the extracted data: { "summary": "Meeting with {invitee.email}", "start": { "dateTime": "{event.start_time}" }, "end": { "dateTime": "{event.end_time}" } }.
  5. For the event.canceled trigger, extract the event.id and send a DELETE request to https://www.googleapis.com/calendar/v3/calendars/primary/events/{event.id} to remove the canceled meeting from Google Calendar.

Developer Warnings & API Gotchas

  • Ensure that the event.id from Calendly matches the event ID format expected by Google Calendar, as discrepancies can lead to failed DELETE requests.
  • When constructing the POST request to Google Calendar, confirm that the start_time and end_time are in the correct ISO 8601 format; otherwise, Google Calendar will reject the event creation.
  • Be aware that if multiple events are scheduled in quick succession, your webhook may receive overlapping requests, which could lead to race conditions if not handled properly.
