# About Bookings Time Slots

The Bookings [Time Slots API](https://dev.wix.com/docs/api-reference/business-solutions/bookings/time-slots/time-slots-v2/introduction.md) enables you to retrieve information about when services are available for booking.
It provides detailed availability data, capacity information, and booking restrictions to help customers find and book the right time slots.

The [Availability Time Slots Configuration Service Plugin](https://dev.wix.com/docs/api-reference/business-solutions/bookings/time-slots/availability-time-slots-configuration-service-plugin/introduction.md) allows you to customize how Wix calculates available time slots, including service duration, resources, locations, and duration adjustments based on customer choices.
