API to get appointment details

I'm currently using the native Appointment App within ClickFunnels and have configured a webhook to send booking data to an external automation platform (Make.com). However, the webhook payload does not include the appointment date and time, which is critical for my workflow.

Could you please confirm:

Is there a way to include the appointment date and time in the webhook payload?

If not, is there a public or private API endpoint available to retrieve full appointment details, including date and time?

This functionality is essential for integrating bookings into our task management system. I'd appreciate any guidance or workarounds you can provide.
