Group reservations allow you to reserve different locations for various people \(groups\) for the same meeting. This API runs in the `sn_wsd_rsv` namespace. To access this API, the caller must have the sn\_wsd\_core.workplace\_user role and the Workplace Reservation Management \(sn\_wsd\_rsv\) plugin must be activated. For additional information on Workplace Reservation Management, see [Workplace Reservation Management](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/employee-service-management/workplace-rsv-mgmt-feat.md). **Parent Topic:**[REST API reference](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/api-reference/rest-apis/api-rest.md) ## WSD Group Reservation - GET /api/sn\_wsd\_rsv/group\_reservation/\{parent\_id\} Returns the parent and all child reservations for a specified group reservation. ### URL format Versioned URL: `/api/sn_wsd_rsv/{api_version}/group_reservation/{parent_id}` Default URL: `/api/sn_wsd_rsv/group_reservation/{parent_id}` **Note:** Available versions are specified in the [REST API Explorer](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/api-reference/rest-api-explorer/use-REST-API-Explorer.md). For scripted REST APIs there is additional version information on the [Scripted REST Service form](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/api-reference/rest-api-explorer/c_CustomWebServices.md). ### Supported request parameters
