Delete openTypeExtension

Namespace: microsoft.graph

Important

APIs under the /beta version in Microsoft Graph are subject to change. Use of these APIs in production applications is not supported. To determine whether an API is available in v1.0, use the Version selector.

Caution

Existing apps that use this feature with baseTask or baseTaskList should be updated, as the to-do API set built on these resources is deprecated as of May 31, 2022. That API set will stop returning data on August 31, 2022. Please use the API set built on todoTask.

Delete an open extension (openTypeExtension object) from the specified instance of a resource.

For the list of resources that support open extensions, see the table in the Permissions section.

This API is available in the following national cloud deployments.

Global service	US Government L4	US Government L5 (DOD)	China operated by 21Vianet

Permissions

Depending on the resource you're deleting the extension from and the permission type (delegated or application) requested, the permission specified in the following table is the least privileged required to call this API.

HTTP request

In the request, identify the resource instance, use the extensions navigation property of that instance to identify the extension, and do a DELETE on that extension instance.

DELETE /administrativeUnits/{administrativeUnitId}/extensions/{extensionId}
DELETE /devices/{deviceId}/extensions/{extensionId}
DELETE /users/{userId|userPrincipalName}/events/{eventId}/extensions/{extensionId}
DELETE /groups/{groupId}/extensions/{extensionId}
DELETE /groups/{groupId}/events/{eventId}/extensions/{extensionId}

Note: The previous syntax shows some common ways to identify a resource instance, in order to delete an extension from it. All other syntax that allows you to identify these resource instances supports deleting open extensions from them in a similar way.
