/availability/check-times

This endpoint available validates slots for an appointment. If a slot is valid and available, the response will include "valid": true. Otherwise, if a time is not a valid slot or not an available slot, "valid": false will be returned along with a reason.

Checking times on separate calendars at once is supported, but validation happens per-calendar and global limits like resources will only be considered for individual calendars.

Post an array to check multiple times at once:
