When Square and Calendly operate independently, payment confirmations can be missed, leading to double bookings. For instance, if a customer pays for a service via Square but the payment data isn't sent to Calendly, the scheduling team may inadvertently allow another client to book the same slot. This results in manual data entry by the operations team to reconcile appointments and payments, wasting valuable time and increasing the risk of human error.

Top Ways to Automate Square & Calendly

  • Automated Appointment Confirmation: Instantly send confirmation emails to clients upon booking through Calendly, ensuring they receive all necessary details while automatically updating their payment status in Square.
  • Seamless Payment Processing: Automatically generate invoices in Square for each appointment scheduled in Calendly, allowing for immediate payment collection and reducing administrative overhead.
  • Real-Time Availability Sync: Maintain accurate availability across both platforms, preventing double bookings and ensuring that your calendar reflects real-time changes, thus enhancing customer satisfaction.

How to Build the Square → Calendly Sync

  1. Set up a webhook in Square to listen for the 'payment.completed' event.
  2. Configure the webhook to send a payload containing relevant data such as 'amount', 'currency', 'customer_email', and 'transaction_id' to your endpoint.
  3. On your endpoint, extract the necessary fields from the Square webhook payload.
  4. Use the Calendly API to create an event by sending a POST request to the '/scheduled_events' endpoint with the extracted data, ensuring to include the 'customer_email' and 'transaction_id' for tracking.
  5. Confirm that the event is created successfully in Calendly and log any errors for troubleshooting.

Developer Warnings & API Gotchas

  • Ensure that the 'transaction_id' from Square is included in the Calendly event payload to avoid confusion during reconciliations.
  • Be aware that Calendly requires specific time zone formatting; failing to convert the time correctly may lead to scheduling errors.
  • Check that the customer email from Square matches the format expected by Calendly to prevent failed event creations.
