# Microsoft Store v8 Collections b2bLicensePreview API
> Microsoft Store v8 Collections b2bLicensePreview API for game services to query a user's owned products, entitlements, and consumables by product SKU ID.
The b2bLicensePreview API allows your own services to query for a user's products and entitlements.
You can scope your query to particular products, product types, or use other filters in your query.
Your service shouldn't regularly poll for user purchases to avoid call rate limits based on a per-user time window.
Currently, the limit is 100 query requests within a five-minute window for the same user.
Triggering a rate limit causes a 429 HTTP response with information about when the next request can be made.
Results include only products directly owned or entitled to the user account your service is calling on-behalf-of.
Shared entitlements that can appear on the client aren't returned.
For more information on sharing scenarios, see [Product sharing model for games](https://learn.microsoft.com/fundamentals/xstore-product-sharing-model-for-games).
To avoid response timeouts and long response times, you should always specify the exact products you want in your results by using the `productSkuIds` parameter in the request.
Calling without the `productSkuIds` list results in longer response times that increase based on the total number of entitlements and purchases the user made across XBOX and the Microsoft Store App.
b2bLicensePreview is for calls from partner services.
Client apps or games shouldn't call this service directly.
## b2bLicensePreview (Collections v8) vs publisherQuery (Collections v9) to query products
b2bLicensePreview (Collections v8) is the prior Collections service to query user entitlements, but is still available for partner use.
publisherQuery (Collections v9) is the latest and provides expanded features such as exposing XBOX Game Pass subscription status.
There are still scenarios where partners might want to use b2bLicensePreview such as support for LegacyProductIds used by the XBOX Inventory service.

## Request
### Prerequisites
Review [Prerequisites for service-to-service APIs](https://learn.microsoft.com/reference/service-to-service-nav#prerequisites-for-service-to-service-apis).
This API supports both Microsoft Entra ID and delegated auth X-token auth types.
If product configuration isn't published in Partner Center, calls can succeed but return no results.
### Request syntax

| `Content-Type` | `string` | Specifies the request and response type. Currently, the only supported value is `application/json`. |
### Request body
| Parameter | Type | Description | Required |
| ----------------------------- | -------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | ------------------------------------- |
| `beneficiaries` | `UserIdentity` | User for which this item is being consumed. For more information, see [Authenticating with Microsoft Entra ID and User Store IDs](https://learn.microsoft.com/reference/xstore-authenticating-your-service#authenticating-with-microsoft-entra-id-and-user-store-ids). Not required for X-token authentication. | Only for User Store ID authentication |
| `productSkuIds` | `list` | If specified, the service only returns products applicable to the provided product/SKU pairs. Recommended for all service-to-service queries for faster and more reliable results. For more information, see the following table. | No |
| `continuationToken` | `string` | If there are multiple sets of products that can't fit within `maxPageSize`, the response body returns a continuation token when the page limit is reached. To retrieve the remaining results from your query, provide the `continuationToken` in subsequent calls. | No |
| `maxPageSize` | `number` | The maximum number of products to return in one response. The default and maximum value is 100. | No |

| `Game` | A base game product or a game bundle. |
| `Application` | An app within Microsoft Store that isn't listed as a game. |
| `Durable` | A downloadable content purchased once and owned until the product's end date. Also the product type for Add-on bundles and Season Pass bundles. |
| `Consumable` | A Store-managed consumable, where the user's balance (or quantity) is kept and managed on the Collections service. On purchase, the quantity is added to the user's balance and can then be removed by performing a consume request. Users are able to purchase this type of consumable again without it being fulfilled first. |
| `UnmanagedConsumable` | Also called a Developer-managed consumable. Must be fulfilled from the game or game's service before user can purchase the product again. |
| `Pass` | A Store-managed Subscription. Different than an Add-on subscription, which is configured under an app's Add-ons page in Partner Center. |
### Product status values and meaning
| Value | Description |
| ----------- | --------------------------------------------------------------------------------------- |
| `Active` | The product is actively entitled. The user should have access to it. |
| `Revoked` | Most commonly indicates that the user requested a refund. |
| `Expired` | The product was part of an entitlement (usually a subscription) that has since expired. |
| `Banned` | N/A. |
| `Suspended` | N/A. |
### Product acquisitionType values and meaning
| Value | Description |
| ------------- | ------------------------------------------------------------------------------------- |
| `Single` | Direct digital purchase or code redemption. |
| `Recurring` | Owned or entitled through a subscription. |
| `Conditional` | Owned but requires other products to continue use. Ex: Games With Gold obtained games |
#### Understanding the results of Satisfied Entitlements with the `satisfiedByProductIds` field
If the `satisfiedByProductIds` array is empty, the user has a direct entitlement from a direct purchase to the item.
Otherwise if the `satisfiedByProductIds` array has one or more ProductIds, the item is entitled to the user from those products (bundles, subscriptions, etc.).
If the user has both a direct and satisfying entitlement to an item, if `excludeDuplicates` in the request is `True` then the direct entitlement will take priority and `satisfiedByProductIds` will be empty.

### Requesting remaining results with the continuation token
If your query has more results than can be returned in a single response, a continuationToken is provided in the latest response.
You use this continuationToken in a follow-up request by adding it to a copy of the previous request body.
Example:
```html theme={null}
POST https://collections.mp.microsoft.com/v8.0/collections/b2bLicensePreview HTTP/1.1
Host: collections.mp.microsoft.com
Authorization: Bearer eyJ0eXAiOiJKV1QiLCJhbGciOiJSUzI1NiIsIng1dCI6Imwzc1EtNTBjQ0g0e...
User-Agent: MicrosoftStoreServiceSample_1.21.9.0
Content-Type: application/json; charset=utf-8
Content-Length: 2032
{
"continuationToken": "{\"checkSatisfactionIndex\":2}",
"maxPageSize": 2,
"excludeDuplicates": true,
"entitlementFilters": [
"*:Game",
"*:Consumable",
"*:UnmanagedConsumable",
"*:Durable",
"*:Pass"
],
"market": "neutral",
"expandSatisfyingItems": true,
"productSkuIds": [
{"productId": "9N30KZZF4BR9"},
{"productId": "9MXL21XPWWWK"},
{"productId": "9PLRFWZWWF91"},
{"productId": "9MZ0MGGFPLTP"}
],
"beneficiaries": [
{
"identityType": "b2b",
"identityValue": "eyJhbGciOiJSUzI1NiIsImtpZCI6IjYxNTI2OEI4...",
"localTicketReference": ""
}
],
"sbx": "XDKS.1"
}
```
Even if you specify the excludeDuplicates flag, when using a continuation token it's possible to get entries of entitlements that have different status. So verify the results for duplicate entries and if they have a status that isn't Active.
