# About the Availability Time Slots Configuration Service Plugin

The Availability Time Slots Configuration service plugin allows you to customize how Wix calculates available time slots for booking services.

With this service plugin, you can:

- Configure service duration, split intervals, and buffer times.
- Specify which locations the service is offered at.
- Define which [resources](fallback::https://dev.wix.com/docs/api-reference/business-solutions/bookings/resources/resources-v2/introduction) are required and available for booking.
- Calculate duration based on the customer's selected duration variant from [service options and variants](fallback::https://dev.wix.com/docs/api-reference/business-solutions/bookings/services/service-options-and-variants/introduction) and/or selected [add-ons](fallback::https://dev.wix.com/docs/api-reference/business-solutions/bookings/services/add-ons/introduction).
- Configure a bookable duration range for services where the customer selects how long to book. Use the `durationUnit` field to define the unit of time (`HOUR` or `DAY`) and the minimum and maximum durations a customer can choose.

## Get started

Follow these steps to begin implementing your service plugin.

### Step 1 | Choose a framework

You can implement this service plugin with the following [frameworks](fallback::https://dev.wix.com/docs/build-apps/get-started/overview/wix-s-development-frameworks):

+ **Wix CLI:** Learn how to [implement a service plugin with the CLI and the SDK](portalId::9d2c17b5-bdfd-4ef8-95e1-9efa463d13f5resourceId::bb12234f-4332-4fcf-84f7-6049d169868a*fallback::https://dev.wix.com/docs/build-apps/develop-your-app/frameworks/wix-cli/supported-extensions/backend-extensions/service-plugins/add-service-plugin-extensions-with-the-cli).
+ **Self-hosted:** Learn how to [implement a self-hosted service plugin with the SDK and the app dashboard](portalId::63e3acd8-2a9c-421d-8f92-d02930eeb59eresourceId::67e56abc-37a6-4734-81e2-624cee8fdd87*fallback::https://dev.wix.com/docs/build-apps/develop-your-app/frameworks/self-hosting/supported-extensions/backend-extensions/add-self-hosted-service-plugin-extensions-with-the-sdk).

### Step 2 | Configure your service plugin

To configure and customize your plugin, you need to provide important information in the service plugin configuration file. You can [configure your plugin in your app's dashboard](portalId::63e3acd8-2a9c-421d-8f92-d02930eeb59eresourceId::67e56abc-37a6-4734-81e2-624cee8fdd87#step-1--add-a-service-plugin-extension-to-your-app*fallback::https://dev.wix.com/docs/build-apps/develop-your-app/frameworks/self-hosting/supported-extensions/backend-extensions/add-self-hosted-service-plugin-extensions-with-the-sdk#step-1--add-a-service-plugin-extension-to-your-app). For details, see [Availability Time Slots Configuration Extension Configuration](fallback::https://dev.wix.com/docs/rest/business-solutions/bookings/time-slots/availability-time-slots-configuration-service-plugin/extension-config).

### Step 3 | Define handler functions

Use [`availabilityTimeSlotsConfiguration.provideHandlers()`](portalId::63e3acd8-2a9c-421d-8f92-d02930eeb59eresourceId::67e56abc-37a6-4734-81e2-624cee8fdd87#step-4--define-handler-functions*fallback::https://dev.wix.com/docs/build-apps/develop-your-app/frameworks/self-hosting/supported-extensions/backend-extensions/add-self-hosted-service-plugin-extensions-with-the-sdk#step-4--define-handler-functions) to define the following handler functions that implement your custom business logic. Make sure you define all required functions.

| Function                    | Required       |
|-----------------------------|----------------|
| [`listAvailabilityTimeSlotConfigurations()`](fallback::https://dev.wix.com/docs/rest/business-solutions/bookings/time-slots/availability-time-slots-configuration-service-plugin/list-availability-time-slot-configurations)    | Yes            |

## Code examples

Below is an example for implementing the Availability Time Slots Configuration service plugin in your code.

### CLI: Basic code structure

This is the basic code structure for implementing the Availability Time Slots Configuration service plugin with the Wix CLI:

```js
import { availabilityTimeSlotsConfiguration } from '@wix/bookings/service-plugins'

availabilityTimeSlotsConfiguration.provideHandlers({
  listAvailabilityTimeSlotConfigurations: async (payload) => {

    const {request, metadata} = payload;

    // Add your logic here

  }
});
  
```

### Self-hosted: Basic code structure

This is the basic code structure for implementing a self-hosted Availability Time Slots Configuration service plugin:

```js
import { createClient } from '@wix/sdk';
import { availabilityTimeSlotsConfiguration } from '@wix/bookings/service-plugins'

const wixClient = createClient({
  auth: {
    appId: <YOUR_APP_ID>,
    publicKey: <YOUR_APP_PUBLIC_KEY>
  },
  modules: { availabilityTimeSlotsConfiguration }
});

wixClient.availabilityTimeSlotsConfiguration.provideHandlers({
  listAvailabilityTimeSlotConfigurations: async (payload) => {

    const { request, metadata } = payload;

    // Add your logic here

  }
});

// Implement a router to process all requests
express.post('/plugins-and-webhooks/*', (req, res) => {
  wixClient.process(req);
});
  
```

# Sample Flows

This article presents a use case and corresponding sample flow that you can support. It provides a useful starting point as you plan your implementation.

## Provide custom time slot configurations during booking

This flow shows what happens when a customer views available booking times, including when they select service variants or add-ons.

> **Prerequisite:** [Resources](fallback::https://dev.wix.com/docs/api-reference/business-solutions/bookings/resources/resources-v2/introduction) must exist for the services being booked. The merchant may also have configured services with [service options and variants](fallback::https://dev.wix.com/docs/api-reference/business-solutions/bookings/services/service-options-and-variants/introduction) or [add-ons](fallback::https://dev.wix.com/docs/api-reference/business-solutions/bookings/services/add-ons/introduction).

1. A customer opens the Bookings calendar on a site.
2. The customer selects a service, and optionally chooses a duration variant and/or add-ons.
3. Wix calls your [List Availability Time Slot Configurations](fallback::https://dev.wix.com/docs/api-reference/business-solutions/bookings/time-slots/availability-time-slots-configuration-service-plugin/list-availability-time-slot-configurations) implementation with `services.serviceId` for each service. If the customer made choices, the request also includes `services.customerChoices` with:
    - `durationInMinutes`: The duration selected by the customer from the service's [options and variants](fallback::https://dev.wix.com/docs/api-reference/business-solutions/bookings/services/service-options-and-variants/introduction).
    - `addOnIds`: IDs of selected [add-ons](fallback::https://dev.wix.com/docs/api-reference/business-solutions/bookings/services/add-ons/introduction).
4. Your implementation returns a configuration for each service, specifying `duration`, `bufferTimeInMinutes`, `splitIntervalInMinutes`, `resourceTypes`, and `locations`.
5. To set `duration.defaultInMinutes`, your implementation must calculate the correct value based on the customer choices. The [Time Slots API](fallback::https://dev.wix.com/docs/api-reference/business-solutions/bookings/time-slots/time-slots-v2/introduction) forwards customer choices to your implementation without processing them, so your implementation is responsible for using them to calculate the correct duration:
    - **Only `addOnIds`:** Calculate the total duration as the service's base duration from [`service.schedule.availabilityConstraints.sessionDurations`](fallback::https://dev.wix.com/docs/api-reference/business-solutions/bookings/services/services-v2/introduction) plus the [`durationInMinutes`](fallback::https://dev.wix.com/docs/api-reference/business-solutions/bookings/services/add-ons/introduction) of all selected add-ons.
    - **Only `durationInMinutes`:** Use it directly as the slot duration.
    - **Both `addOnIds` and `durationInMinutes`:** The `durationInMinutes` value already includes the service duration plus all selected add-on durations. Use it directly.
    - **Neither:** Use the service's default duration from [`service.schedule.availabilityConstraints.sessionDurations`](fallback::https://dev.wix.com/docs/api-reference/business-solutions/bookings/services/services-v2/introduction).
6. Wix calculates available time slots based on your configuration, resource [schedules](fallback::https://dev.wix.com/docs/api-reference/business-management/calendar/schedules-v3/introduction), and existing [bookings](fallback::https://dev.wix.com/docs/api-reference/business-solutions/bookings/bookings/bookings-reader-v2/introduction).
7. The customer selects a slot and proceeds to book.

## Provide duration range configurations for flexible-duration services

This flow shows what happens when a customer views available booking times for a service that supports a bookable duration range. Instead of fixed durations, the customer selects how long they want to book within a minimum and maximum range.

> **Prerequisite:** [Resources](fallback::https://dev.wix.com/docs/api-reference/business-solutions/bookings/resources/resources-v2/introduction) must exist for the services being booked.

1. A customer opens the Bookings calendar on a site for a flexible-duration service (for example, a conference room that can be booked for 1 to 4 hours).
2. Wix calls your [List Availability Time Slot Configurations](fallback::https://dev.wix.com/docs/api-reference/business-solutions/bookings/time-slots/availability-time-slots-configuration-service-plugin/list-availability-time-slot-configurations) implementation with `services.serviceId` for the service.
3. Your implementation returns a configuration that includes both `duration` and `durationUnit`. For an hourly service:
    - `duration.defaultInMinutes`: The minimum bookable duration in minutes. For example, `60` for a 1-hour minimum. Wix uses this to calculate available start times.
    - `durationUnit.unitType`: `HOUR`
    - `durationUnit.minDuration`: Minimum bookable duration in minutes. For example, `60` for a 1-hour minimum.
    - `durationUnit.maxDuration`: Maximum bookable duration in minutes. For example, `240` for a 4-hour maximum.
4. Wix uses `duration.defaultInMinutes` to calculate available start times and displays them to the customer.
5. After the customer selects a start time, Wix uses `durationUnit` to calculate available end times based on the maximum duration and resource availability.
6. The customer selects an end time and proceeds to book.

For daily services, return only `durationUnit` and leave `duration` empty. Set `durationUnit.unitType` to `DAY` and specify `minDuration` and `maxDuration` in days. For example, `1` for a 1-day minimum and `5` for a 5-day maximum. Wix then calculates availability as full-day windows instead of time slots.

Buffer time in minutes between the end of one slot and the start of the next.

bufferTimeInMinutes

Service duration. Leave empty when `durationUnit.unitType` is `DAY`.

Duration unit configuration for services that support a range of bookable durations.

For hourly duration ranges, return both `duration` (with `defaultInMinutes` set to the minimum duration) and `durationUnit`.
For daily duration ranges, return only `durationUnit` with `unitType` set to `DAY` and leave `duration` empty.

Locations where this service is offered.

You can specify multiple `BUSINESS` locations, but only a single `CUSTOM` or `CUSTOMER` location.

locations

[Resource types](https://dev.wix.com/docs/api-reference/business-solutions/bookings/resources/resource-types-v2/introduction) required to book this service. For example, a room from the "rooms" resource type and a staff member from the "staff" resource type.

resourceTypes

ID of the [schedule](https://dev.wix.com/docs/api-reference/business-management/calendar/schedules-v3/introduction) for this service.

scheduleId

serviceId

Time between available slots' start times in minutes. For example, with 5-minute intervals: `3:00`, `3:05`, and `3:10`.

When the business configures the split interval to match the service duration, this value is the service duration
plus `bufferTimeInMinutes`. The maximum of `58320` therefore covers the longest bookable duration, 40 days
(`57600` minutes), plus the maximum `bufferTimeInMinutes` of `720`.

splitIntervalInMinutes

AvailabilityTimeSlotsConfiguration

Base URI where your service plugin endpoints are deployed. For example, `https://my-app.com`.

providerName

AvailabilityTimeSlotsProviderConfig

Customer's selected choices during the booking flow. Use these values to calculate service configuration properties such as duration.

IDs of [add-ons](https://dev.wix.com/docs/api-reference/business-solutions/bookings/services/add-ons/introduction) selected by the customer.
When specifying this field, we recommend omitting `durationInMinutes`. Wix Bookings then calculates the total duration based on the service duration plus all selected add-on durations.

addOnIds

Duration selected by the customer in minutes. Based on the customer's selection from [service options and variants](https://dev.wix.com/docs/api-reference/business-solutions/bookings/services/service-options-and-variants/introduction).
When using [add-ons](https://dev.wix.com/docs/api-reference/business-solutions/bookings/services/add-ons/introduction), we recommend passing only `addOnIds` instead of `durationInMinutes`. Wix Bookings then calculates the total duration automatically. If you specify both `addOnIds` and `durationInMinutes`, `durationInMinutes` must equal the service duration plus all selected add-on durations.

durationInMinutes

Gender the customer narrowed an "any staff member" selection to.
Only time slots served by staff members of that gender are returned.
Omit to keep "any staff member" unnarrowed.

Requires `genderPubliclyAccessible` to be enabled in the business's [staff member settings](https://dev.wix.com/docs/api-reference/business-solutions/bookings/staff-members/staff-member-settings/introduction). The call fails with `REQUESTED_GENDER_NOT_ALLOWED` when it's disabled.

CustomerChoices

DayOptions

defaultInMinutes

Duration

Duration unit configuration for services with a range of bookable durations.
Defines the unit of time and the minimum and maximum durations a customer can select.

Maximum bookable duration. Value is in minutes when `unitType` is `HOUR`, and in days when `unitType` is `DAY`.
Must be greater than or equal to `minDuration`. Maximum for daily durations is 8 consecutive days.

For example, `240` for a 4-hour maximum or `8` for an 8-day maximum.

maxDuration

Minimum bookable duration. Value is in minutes when `unitType` is `HOUR`, and in days when `unitType` is `DAY`.
Must be less than or equal to `maxDuration`.

For example, `60` for a 1-hour minimum or `1` for a 1-day minimum.

The URI must begin with `https://`, such as `https://my-app.com/v1/my-custom-method`.

absoluteUri

Name of the method to call at the absolute URI, in PascalCase. For example, to call [Get Shipping Rates](https://dev.wix.com/docs/api-reference/business-solutions/e-commerce/extensions/shipping-rates/shipping-rates-integration-service-plugin/get-shipping-rates) on an alternative URI, specify `GetShippingRates`.

methodName

AlternativeUri

Service plugin for customizing how Wix calculates available time slots for booking services.

Retrieves availability time slot configurations for the specified services.

Wix calls this method when a customer views available booking times or books a service. For example:
- When a customer loads the Bookings calendar to select a time slot, [List Availability Time Slots](https://dev.wix.com/docs/api-reference/business-solutions/bookings/time-slots/time-slots-v2/list-availability-time-slots) calls this method.
- When a customer books a service, [Get Availability Time Slot](https://dev.wix.com/docs/api-reference/business-solutions/bookings/time-slots/time-slots-v2/get-availability-time-slot) calls this method.

Wix uses the returned configurations to calculate available time slots, considering:
- Service duration.
- Split interval and buffer time.
- Service locations.
- Required resource types and available resources.

Your implementation must return a configuration for each service in the request, in the same order.
All fields in the response must be returned unless explicitly marked as optional.

Returns a configuration with a bookable duration range. The data payload will include the following object as an encoded JWT. For the purposes of this example, we show the request and response objects decoded.

List the availability time slot configuration with duration range - decoded JWT

ListAvailabilityTimeSlotConfigurations

The data payload will include the following object as an encoded JWT. For the purposes of this example, we show the request and response objects decoded.
