When Calendly and Xero operate independently, scheduling conflicts arise, leading to double bookings. For instance, if a client schedules a meeting via Calendly, the corresponding invoice in Xero may not reflect this appointment, causing confusion for the accounting team. This results in manual data entry where team members must cross-reference calendars and invoices, wasting valuable time and increasing the risk of errors in client billing.

Top Ways to Automate Calendly & Xero

Automated Appointment Scheduling: Seamlessly sync your Calendly appointments with Xero, ensuring that every meeting automatically generates an invoice or updates your financial records without manual input.
Real-Time Financial Updates: Instantly reflect changes in your scheduling within Xero, allowing for accurate tracking of billable hours and ensuring that your financial data is always up-to-date.
Streamlined Client Communication: Automatically send confirmation emails and reminders to clients through Calendly, while also updating their payment status in Xero, enhancing the overall client experience and reducing no-shows.

How to Build the Calendly → Xero Sync

Set up a webhook in Calendly to listen to the 'Invitee Created' event. This will trigger whenever a new appointment is scheduled.
Configure the webhook to send a POST request to your integration endpoint with the following payload: { "event": "invitee.created", "payload": { "email": "{{invitee.email}}", "name": "{{invitee.name}}", "event_type": "{{event.event_type}}", "start_time": "{{event.start_time}}" } }}.
On your integration endpoint, extract the necessary data from the payload: email, name, event_type, and start_time.
Use the Xero API to create a new invoice. Make a POST request to https://api.xero.com/api.xro/2.0/Invoices with the extracted data formatted as follows: { "Type": "ACCREC", "Contact": { "Name": "{{name}}", "EmailAddress": "{{email}}" }, "Date": "{{start_time}}", "LineItems": [{ "Description": "Appointment for {{event_type}}", "Quantity": 1, "UnitAmount": 100 }] }.
Verify the response from Xero to ensure the invoice was created successfully.

Developer Warnings & API Gotchas

Ensure the date format from Calendly matches the format expected by Xero; otherwise, the invoice creation will fail.
Be cautious about duplicate entries in Xero; if the same invitee books multiple appointments, implement logic to check for existing invoices before creating new ones.
When mapping the event type to the invoice description, ensure that the description aligns with Xero's predefined categories to avoid misclassification.
