# About the Service Options and Variants API
 
 The Service Options and Variants API lets you manage custom options for [services](portalId::b85dea5b-341b-493b-b99e-4d4ca12baaa2resourceId::d1c98af6-5ad1-4df4-a38f-0b67797af4d4slug::setup*fallback::https://dev.wix.com/docs/sdk/backend-modules/bookings/services/introduction).

You can configure options based on:

- The [staff member](fallback::https://dev.wix.com/docs/rest/business-solutions/bookings/staff-members/introduction)
  providing the service.
- Appointment duration.
- A custom parameter, such as customer age or equipment type.

Each option includes a list of choices that customers can select when booking a
service. A service variant is a unique combination of all choices made by the
customer during booking. Only a single option is permitted per
service, meaning a variant corresponds directly to 1 choice from that option.

## Before You Begin

Note the following before coding:

- Only 1 `serviceOptionsAndVariants` object is allowed per service.
- Only 1 option is supported per `serviceOptionsAndVariants` object.
- Variants aren't automatically calculated from the specified option and choices
  in the [Create Service Options and Variants](fallback::https://dev.wix.com/docs/rest/business-solutions/bookings/services/service-options-and-variants/create-service-options-and-variants) call.
  Instead, you must manually define all variants when calling
  Create Service Options and Variants.
- After configuring a staff member-based option for a service, Wix Bookings
  automatically adds a new choice and variant when a new staff member is added
  to the service. Each new variant uses the service’s
  `payment.varied.defaultPrice`. Staff member-based choices and variants are
  automatically deleted if a staff member is removed from the service or the
  entire business.

## Use Cases

- [Create staff member-based service variants](fallback::https://dev.wix.com/docs/rest/business-solutions/bookings/services/service-options-and-variants/sample-flows#create-staff-member-based-service-variants).
- [Create service variants based on booked equipment](fallback::https://dev.wix.com/docs/rest/business-solutions/bookings/services/service-options-and-variants/sample-flows#create-service-variants-based-on-the-booked-equipment).

## Terminology

- **Option**: A modification of a service based on staff member, event duration,
  or custom parameters (like customer age). Each option includes a list of
  supported **choices** that customers select when booking. Services can have
  only 1 option.
- **Choice**: A specific value for a service **option**. For example, the option
  `ageGroup` may include choices like `child`, `student`, `adult`, and `senior`,
  each potentially priced differently.
- **Variant**: A unique combination of all choices made by the customer when
  booking. For example, `{"time": "afternoon", "ageGroup": "adult", "equipment": "kettlebells"}`.
  Note that since a service can currently only have 1 option, variants are
  limited to that option and its choices.

# Sample Flows

This article shares some possible use cases you could support, as well as a
sample flow that supports each use case. This can be a helpful jumping off
point as you plan your implementation.

## Create staff member-based service variants

You can set up staff member-based service variants. This allows the business to
offer customers different service prices depending on which staff member is
providing the service.

To create staff member-based variants:

1. Call *Query Services*
   ([SDK](portalId::b85dea5b-341b-493b-b99e-4d4ca12baaa2resourceId::d1c98af6-5ad1-4df4-a38f-0b67797af4d4slug::query-services*fallback::https://dev.wix.com/docs/sdk/backend-modules/bookings/services/query-services) | [REST](fallback::https://dev.wix.com/docs/rest/business-solutions/bookings/services/services-v2/query-services)).
   Save the relevant service ID and its `staffMemberIds` array.
1. Call *Create Service Options and Variants*
   ([SDK](fallback::https://dev.wix.com/docs/sdk/backend-modules/bookings/service-options-and-variants/create-service-options-and-variants) | [REST](fallback::https://dev.wix.com/docs/rest/business-solutions/bookings/services/service-options-and-variants/create-service-options-and-variants)),
   specifying `serviceId`, `STAFF_MEMBER` as `options.values.type`,
   as well as all staff member IDs in `variants.values.choices.staffMemberId`.
   Make sure to also specify the only supported option ID in every
   `variants.values.choices.optionId` field.  
   Optionally, you can specify different prices for each staff member in
   `variants.values.choices.price`.

## Create service variants based on the booked equipment

You can set up service variants based on the booked equipment. This lets
the business offer different service prices depending on which equipment the
customer has booked.

To create equipment-based variants:

1. Call *Query Services*
   ([SDK](portalId::b85dea5b-341b-493b-b99e-4d4ca12baaa2resourceId::d1c98af6-5ad1-4df4-a38f-0b67797af4d4slug::query-services*fallback::https://dev.wix.com/docs/sdk/backend-modules/bookings/services/query-services) | [REST](fallback::https://dev.wix.com/docs/rest/business-solutions/bookings/services/services-v2/query-services)). Save the relevant service ID.
1. Call *Create Service Options and Variants*
   ([SDK](fallback::https://dev.wix.com/docs/sdk/backend-modules/bookings/service-options-and-variants/create-service-options-and-variants) | [REST](fallback::https://dev.wix.com/docs/rest/business-solutions/bookings/services/service-options-and-variants/create-service-options-and-variants)),
   specifying `serviceId`, `CUSTOM` as `options.values.type`,
   `Equipment` as `options.customData.name`, and all supported equipment
   choices in the `options.customData.choices` array. Additionally, make sure
   to repeat all supported choices in `variants.values.choices.custom`
   and to specify the only supported option ID in every
   `variants.values.choices.optionId` field.  
   Optionally, you can specify different prices for each variant in
   `variants.values.choices.price`.

# Service Variants and Options: Supported Filters and Sorting

This article covers field support for filtering and sorting in
*Query Service Options And Variants*
([SDK](fallback::https://dev.wix.com/docs/sdk/backend-modules/bookings/service-options-and-variants/query-service-options-and-variants) | [REST](fallback::https://dev.wix.com/docs/rest/business-solutions/bookings/services/service-options-and-variants/query-service-options-and-variants)).

## Filtering

The following table shows field support for filters for the
`serviceOptionsAndVariants` object:

| Field | Supported Filters | Sortable |
| ----- | ----------------- | -------- |
| `id` | `$eq`, `$ne`, `$in` | Sortable |
| `serviceId` | `$eq`, `$ne`, `$in` | Sortable |
| `options.values` | `$exists` |   |
| `options.values.id` | `$hasSome`, `$hasAll` |   |
| `options.values.type` | `$hasSome`, `$hasAll` |   |
| `options.values.optionSpecificData.customData.name` | `$hasSome`, `$hasAll` |   |
| `variants.values` | `$exists` |   |
| `variants.values.choices.choice.custom.value` | `$hasSome`, `$hasAll` |   |
| `variants.values.price` | `$hasSome`, `$hasAll` |   |
| `variants.values.choices.optionId` | `$hasSome`, `$hasAll` |   |

## Sorting 

*Query Service Options And Variants*
([SDK](fallback::https://dev.wix.com/docs/sdk/backend-modules/bookings/service-options-and-variants/query-service-options-and-variants) | [REST](fallback::https://dev.wix.com/docs/rest/business-solutions/bookings/services/service-options-and-variants/query-service-options-and-variants))
runs with this default:

- Sorted by `id` in `ASC` order.
- `cursorPaging.limit` set to `100`.

Specify the `sort` object in the following format:

```json
"sort" : [ 
  { 
    "fieldName":"sortField1",
    "order":"ASC"
  },
  { 
    "fieldName":"sortField2",
    "order":"ASC"
  },
]
```

## Paging 

By default `pagingMetadata.cursors` are returned, unless you specifically pass
`query.paging`.

The maximum for `cursorPaging.limit` is `100`.

If you pass a cursor token that you've received in a previous query response,
passing additional sort or filter information results in an invalid cursor
error. This is because the received cursor token already holds all the needed information
for sort and filter. Changing the sort and filter properties during the span of
a cursor query isn't supported. You may provide a different limit though.
