Thank you for sharing the details. To help narrow down the issue, could you confirm if the
time range (start and end date/time) and
timezone parameters are being set correctly when you run the appointment availability check in VAPI? Incorrect or missing values for these fields can cause the tool to return no available slots, even if everything else is set up properly.
Let me know what values you are using for these parameters.
