Grant an appRoleAssignment to a user

Namespace: microsoft.graph

Assign an app role to a user, creating an appRoleAssignment object. To grant an app role assignment to a user, you need three identifiers:

  • principalId: The id of the user to whom 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 user.

This API is available in the following national cloud deployments.

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 /users/{id | userPrincipalName}/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

The following example shows a request.

POST https://graph.microsoft.com/v1.0/users/cde330e5-2150-4c11-9c5b-14bfdc948c79/appRoleAssignments
