Grant an appRoleAssignment to a group

Namespace: microsoft.graph

Use this API to assign an app role to a security group. All direct members of the group will be considered assigned. Security groups with dynamic memberships are supported. To grant an app role assignment to a group, you need three identifiers:

  • principalId: The ID of the group to which you are assigning the app role.
  • resourceId: The ID of the resource servicePrincipal that has defined the app role.
  • appRoleId: The ID of the appRole (defined on the resource service principal) to assign to the group.

Additional licenses might be required to use a group to manage access to applications.

This API is available in the following national cloud deployments.

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

Permissions

Choose the permission or permissions marked as least privileged for this API. Use a higher privileged permission or permissions only if your app requires it. For details about delegated and application permissions, see Permission types. To learn more about these permissions, see the permissions reference.

Permission type Least privileged permissions Higher privileged permissions
Delegated (work or school account) AppRoleAssignment.ReadWrite.All Not available.
Delegated (personal Microsoft account) Not supported. Not supported.
Application AppRoleAssignment.ReadWrite.All Not available.

Important

In delegated scenarios with work or school accounts, the signed-in user must be assigned a supported Microsoft Entra role or a custom role with a supported role permission. The following least privileged roles are supported for this operation:

  • Directory Synchronization Accounts - for Microsoft Entra Connect and Microsoft Entra Cloud Sync services
  • Directory Writer
  • Hybrid Identity Administrator
  • Identity Governance Administrator
  • Privileged Role Administrator
  • User Administrator
  • Application Administrator
  • Cloud Application Administrator

HTTP request

POST /groups/{groupId}/appRoleAssignments

Note

As a best practice, we recommend creating app role assignments through the appRoleAssignedTo relationship of the resource service principal, instead of the appRoleAssignments relationship of the assigned user, group, or service principal.

Request headers

Name Description
Authorization Bearer {token}. Required. Learn more about authentication and authorization.
Content-type application/json. Required.

Request body

In the request body, supply a JSON representation of an appRoleAssignment object.

The following table lists the properties that are required when you create the appRoleAssignment. Specify other writable properties as necessary for your appRoleAssignment.

Property Type Description
appRoleId Guid The identifier (id) for the app role which is assigned to the principal. This app role must be exposed in the appRoles property on the resource application's service principal (resourceId). If the resource application has not declared any app roles, a default app role ID of 00000000-0000-0000-0000-000000000000 can be specified to signal that the principal is assigned to the resource app without any specific app roles.
principalId Guid The unique identifier (id) for the group being granted the app role.
resourceId Guid The unique identifier (id) for the resource service principal for which the assignment is made.

Response

If successful, this method returns a 201 Created response code and an appRoleAssignment object in the response body.
