Grant an appRoleAssignment for a service principal

Namespace: microsoft.graph

Assign an app role for a resource service principal, to a user, group, or client service principal.

App roles that are assigned to service principals are also known as application permissions. Application permissions can be granted directly with app role assignments, or through a consent experience.

To grant an app role assignment, you need three identifiers:

principalId: The id of the user, group or client servicePrincipal to which you are assigning the app role.
resourceId: The id of the resource servicePrincipal which has defined the app role.
appRoleId: The id of the appRole (defined on the resource service principal) to assign to a user, group, or service principal.

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 and Application.Read.All	AppRoleAssignment.ReadWrite.All and Directory.Read.All
Delegated (personal Microsoft account)	Not supported.	Not supported.
Application	AppRoleAssignment.ReadWrite.All and Application.Read.All	AppRoleAssignment.ReadWrite.All and Directory.Read.All

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

You can address the service principal using either its id or appId. id and appId are referred to as the Object ID and Application (Client) ID, respectively, in app registrations in the Microsoft Entra admin center.

POST /servicePrincipals/{id}/appRoleAssignedTo
POST /servicePrincipals(appId='{appId}')/appRoleAssignedTo

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.

Response

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