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.

Get the list of security principals (users, groups, and service principals) that are assigned to a specific role for different scopes either directly or transitively. You can use the $count query parameter to also get the count.

This API is supported for the directory (Microsoft Entra ID) provider only.

To list the direct and transitive role assignments for a specific principal, use the List transitiveRoleAssignments API.

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) RoleManagement.Read.Directory Directory.Read.All, RoleManagement.ReadWrite.Directory
Delegated (personal Microsoft account) Not supported. Not supported.
Application RoleManagement.Read.Directory Directory.Read.All, RoleManagement.ReadWrite.Directory

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 Readers
  • Global Reader
  • Privileged Role Administrator

Important

When an application queries a relationship that returns a directoryObject type collection, if it doesn't have permission to read a certain resource type, members of that type are returned but with limited information. For example, only the @odata.type property for the object type and the id is returned, while other properties are indicated as null. With this behavior, applications can request the least privileged permissions they need, rather than rely on the set of Directory.* permissions. For details, see Limited information returned for inaccessible member objects.

HTTP request

GET /roleManagement/directory/roleDefinitions/{unifiedRoleDefinitionId}/assignedPrincipals(transitive=@transitive,directoryScopeType='@directoryScopeType',directoryScopeId='@directoryScopeId')

Function parameters

In the request URL, provide the following query parameters with values. The following table shows the parameters that can be used with this function.

Parameter Type Description
transitive Boolean Indicates whether to include principals assigned through group membership (direct or transitive). false by default.
directoryScopeType String The directory scope to get assigned principals for. Supported values are tenant, administrativeUnit, and resource.
directoryScopeId String ID of the directory scope to get assigned principals for. By default, all scopes are considered.

You can also combine all the supported function parameters in one request for fine-grained results.

Example query patterns for directoryScopeType

Scope Query Supported for
All scopes /assignedPrincipals(transitive={true | false}) All roles
Tenant scope /assignedPrincipals(directoryScopeType='tenant', transitive={true | false}) All roles
All administrative unit scopes /assignedPrincipals(directoryScopeType='administrativeUnit', transitive={true | false}) Directory roles
Specific administrative unit scope /assignedPrincipals(directoryScopeType='administrativeUnit', directoryScopeId ='{roleDefinitionId | templateId}', transitive={true | false}) Directory roles
All resource scopes /assignedPrincipals(directoryScopeType='resource', transitive={true | false}) Directory roles
Specific resource scope /assignedPrincipals(directoryScopeType='resource', directoryScopeId ='{roleDefinitionId | templateId}', transitive={true | false}) Directory roles

Optional query parameters

This method supports the $count, $select, $filter, and $orderby OData query parameters to help customize the response. You can also filter by the type of object using OData casting. For example, /assignedPrincipals(transitive=false)/microsoft.graph.user and /assignedPrincipals(transitive=true)/microsoft.graph.servicePrincipal/$count. For general information, see OData query parameters.

Request headers

Name Description
Authorization Bearer {token}. Required. Learn more about authentication and authorization.
ConsistencyLevel eventual. Required. For more information about the use of ConsistencyLevel, see Advanced query capabilities on directory objects.

Request body

Don't supply a request body for this method.

Response

If successful, this function returns a 200 OK response code and a directoryObject collection in the response body.

Examples

For the examples in this section, consider the following role assignment scenario. A user named User1 has both direct and transitive role assignments as follows:

User Group Role Scope
User1
6c62e70d-f5f5-4b9d-9eea-ed517ed9341f		 Role1 Scope1
User1
6c62e70d-f5f5-4b9d-9eea-ed517ed9341f		 Role1 Scope2
Group1
86b38db7-6e8b-4ad2-b2aa-ced7f09486c1
(User1 is a member)		 Role1 Scope1
Group2
182351a6-d974-4d18-88ae-8a148da44cd2
(User1 is a member)		 Role1 Scope1
Group3
b93d5379-a464-4db5-b8e1-694910f1e11e
(User2 is a member)
(User3 is a member)		 Role1 Scope3
  • User1 is assigned the Role1 role directly at Scope1 scope.
  • User1 is assigned the Role1 role directly at Scope2 scope.
  • User1 is member of the Group1 group and Group1 is assigned the Role1 role at Scope1 scope.
  • User1 is member of the Group2 group and Group2 is assigned the Role1 role at Scope1 scope.
  • User2 is member of the Group3 group and Group3 is assigned the Role1 role at Scope3 scope.
  • User3 is member of the Group3 group and Group3 is assigned the Role1 role at Scope3 scope.

Example 1: Get a count of direct and transitive assigned principals for all scopes

Request

GET https://graph.microsoft.com/beta/roleManagement/directory/roleDefinitions/644ef478-e28f-4e28-b9dc-3fdde9aa0b1f/assignedPrincipals(transitive=true)/$count

Response

The above request returns a count of 6 representing the following role assignments:

  • Two direct role assignments to User1 at Scope1 and Scope2
  • Two transitive role assignments to User1 through Group1 and Group2
  • Two transitive role assignments to User 2 and User3 through Group3.
HTTP/1.1 200 OK
Content-type: text/plain

6

Based on the same scenario, the following examples show the counts that are returned for each query pattern:

Example Count
/assignedPrincipals(transitive=false)/$count 4
(User1, Group1, Group2, Group3)
/assignedPrincipals(transitive=false)/microsoft.graph.user/$count 1
(User1)
/assignedPrincipals(transitive=true)/microsoft.graph.user/$count 3
(User1, User2, User3)
/assignedPrincipals(transitive=false)/microsoft.graph.group/$count 3
(Group1, Group2, Group3)
/assignedPrincipals(transitive=true)/microsoft.graph.group/$count 3
(Group1, Group2, Group3)

Example 2: Get directly assigned principals for a specific administrative unit scope and directory role
