# purchase.mp.microsoft.com/v8.0/b2b/clawback/sastoken

> Microsoft Store v8 clawback SAS token endpoint that generates an Azure Storage SAS token for reading your game service's Clawback event message queue.

This endpoint generates an [SAS token](https://learn.microsoft.com/azure/storage/common/storage-sas-overview) to authenticate and access your Clawback event message queue.
For more information on a Clawback event message queue, see [Managing refunds and chargebacks from your service](https://devdocs.xbox.com/publishing/xstore-commerce/xstore-managing-refunds.md).

## Prerequisites

Review [Prerequisites for service-to-service APIs](https://devdocs.xbox.com/publishing/xstore-commerce/xstore-authenticating-service.md).

For more information on the onboarding process, see [Required setup / onboarding request](https://devdocs.xbox.com/publishing/xstore-commerce/xstore-managing-refunds.md#required-setup--onboarding-request).
