List group members

Namespace: microsoft.graph

Get a list of the group's direct members. A group can have users, organizational contacts, devices, service principals and other groups as members. This operation is not transitive.

Important

This API has a known issue where service principals are not listed as group members in v1.0. Use this API on the beta endpoint instead or the /groups/{id}?$expand=members API. Note the limitations of $expand on directory objects.

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

When an application queries a relationship that returns a directoryObject type collection, if it does not have permission to read a certain derived type (like device), members of that type are returned but with limited information. 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 /groups/{id}/members

Optional query parameters

This method supports the $filter, $count, $select, $search, $top, $search, and $expand OData query parameters to help customize the response. The default and maximum page sizes are 100 and 999 group objects respectively. Some queries are supported only when you use the ConsistencyLevel header set to eventual and $count. For more information, see Advanced query capabilities on directory objects.

OData cast is also enabled. For example, /groups/{id}}/members/microsoft.graph.user retrives group members that are users.

Request headers

Header Value
Authorization Bearer {token}. Required. Learn more about authentication and authorization.
ConsistencyLevel eventual. This header and $count are required when using the $search, $filter, $orderby, or OData cast query parameters. It uses an index that might not be up-to-date with recent changes to the object.

Request body

Don't supply a request body for this method.

Response

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

An attempt to filter by an OData cast that represents an unsupported member type returns a 400 Bad Request error with the Request_UnsupportedQuery code. For example, /groups/{id}}/members/microsoft.graph.group when the group is a Microsoft 365 group will return this error, because Microsoft 365 groups cannot have other groups as members.
