Wix Bookings comprises multiple interconnected components that enable booking flows for customers and management capabilities for business owners. This architecture is flexible: you can extend, customize, or replace elements of the business solution to meet your needs.
This article describes the main components of the Wix Bookings architecture, available customizations, and the standard single-service booking flow.
The Services V2 API manages each business's offerings and all the information that customers need when deciding whether to book.
Wix Bookings supports 3 service types:
Booking policies control when customers can book, limit the maximum number of participants, and manage cancellation and rescheduling rules. You can create and manage these policies using the Booking Policies API. Services are associated with booking forms that customers fill out when making a booking. Learn about how Wix Bookings integrates with Wix Forms.
You can extend and customize services in the following ways:
The Staff Members API manages staff members who provide services and their working hour schedules. Staff availability is a key factor in determining which time slots are available for appointment bookings.
The Resources V2 API manages physical assets like meeting rooms or equipment that services require. You must link resources to resource types to make them bookable and prevent double bookings. Customers can book a service only if all required resources are available during the selected time.
Important: Wix Bookings automatically creates and manages a resource for each staff member. Use the Staff Members API to manage staff because using the Resources V2 API for staff can lead to data conflicts.
You can extend and customize staff and resource management in the following ways:
The Time Slots V2 API determines which time slots are available for booking based on service type and relevant constraints:
Wix Bookings validates all these factors at multiple points in the booking flow:
The Bookings Writer V2 API handles the creation and management of both single-service and multi-service bookings.
After the session takes place, you can track and manage customer attendance using the Attendance API.
Wix Bookings integrates with Wix Forms to collect customer information during the booking process. Each service has an associated booking form that customers complete when making a booking.
When a customer completes a booking form, Wix Forms creates a form submission that contains the customer's responses. The system automatically links this submission data to the booking, and you can access it through the Form Submissions API. Learn more about how Wix Bookings integrates with Wix Forms.
The system creates a booking once the customer selects 1 or more services with specific time slots and completes the booking form. The booking then moves through the payment and checkout flow. After payment completes, the system either confirms the booking automatically or sends it to the business for manual approval, depending on the service configuration.
You can extend and customize the booking experience in the following ways:
Wix Bookings integrates with the Wix eCommerce platform to handle payments and order management.
The Wix eCommerce system automatically uses the booking ID as a catalog item reference and handles pricing calculations, tax, and payment processing. Add-ons appear as additional fees in the eCommerce checkout.
By default, the system creates a checkout using the Checkout API and redirects customers to complete payment.
Once payment processes, Wix eCommerce creates an order and updates the booking status based on the service configuration (for example, CONFIRMED for automatic approval or PENDING for manual approval).

You can customize the checkout and payment experience in the following ways:
options.paymentStatus set to PAID to update the booking status to CONFIRMED.
Then, create an order using the Orders API to record the transaction with your custom payment details.
This ensures the booking is properly tracked in both the Bookings and eCommerce systems.Wix Bookings integrates with Wix Calendar to manage schedules and events. Once the booking is confirmed, Wix Bookings adds the session to the business's booking calendar and to the schedules of the relevant staff members, rooms, and other resources. The booking calendar displays all scheduled sessions and can be filtered by service, staff, and other criteria to help manage daily operations. Learn more about how Wix Bookings integrates with Wix Calendar.
You can connect and sync external calendars with Wix Bookings using the External Calendars API. This allows staff members to sync their Wix Bookings calendar with Google Calendar, Microsoft Outlook, or Apple Calendar for bidirectional synchronization.
Important: The Calendar V3 APIs are standalone services and aren't part of the Bookings APIs. However, the External Calendars API is part of Bookings.
Wix Bookings automatically sends notifications to keep Wix users and customers informed about booking events.
Wix users receive notifications for events such as:
Customers receive notifications for events such as:
You can extend the notification system by providing pre-installed automations that trigger custom notifications (or other actions) when specific conditions are met.
