Please I am having issues with my customers being able to choose different appointment slots. If a customer books for Monday at 9:00am, it should be completely taken off the available slots instead it still shows that same time and day available causing confusion. Where could the problem be coming from?

The issue is likely with your "Schedule Event" tool not updating the calendar after a booking. To fix this, ensure your workflow includes the following step after a customer confirms their slot:

plaintext
If appointment details are confirmed:
    Use the "Schedule Event" tool to book the slot in your calendar system.

This will remove the booked slot from availability and prevent double bookings. For more details, see the [Vapi appointment scheduling workflow documentation](https://docs.vapi.ai/workflows/examples/appointment-scheduling).

@Chur_mahh22 r u using google calendar?

Yes I am . I did an inbuilt integration

the problem may be from your tool, the api u r calling to book it. It should block the calendar

By API blocking it, what do you mean? Can you walk me through how to check it?
