Failed bookings
A failed booking means an appointment was meant to be created but could not be completed. The booking status is documented as failed in this case. This article explains the most common causes and how to prevent them.
A failed booking is distinct from an appointment that was not offered. Failed means the booking attempt started but did not end successfully.
Common causes
- No suitable slots were available at the desired time.
- The booking window or meeting duration did not allow an appointment.
- Required details for the booking were missing in the conversation.
- A time had already been taken in the meantime.
Many of these causes can be avoided through a careful configuration of the booking settings. In particular, check available time slots, booking window and meeting duration.
How to prevent failed bookings
- Provide enough time slots so that slots are created.
- Choose a booking window that leaves enough lead time and room.
- Adjust the meeting duration so that it matches the time slots.
- Capture required details through suitable result fields.
- Check the campaign with a test call before the start.
Hinweis: If bookings fail regularly, first check the time slots, the booking window and the meeting duration. Often suitable slots are simply missing.
