Add members

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.

Add a member to a security or Microsoft 365 group. When using the API to add multiple members in one request, you can add up to only 20 members.

The following table shows the types of members that can be added to either security groups or Microsoft 365 groups.

Object type	Member of security group	Member of Microsoft 365 group
User
Security group
Microsoft 365 group
Device
Service principal
Organizational contact

This API is available in the following national cloud deployments.

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

Permissions

The following table shows the least privileged permission that's required by each resource type when calling this API. To learn more, including how to choose permissions, see Permissions.

Supported resource	Delegated (work or school account)	Delegated (personal Microsoft account)	Application
device	GroupMember.ReadWrite.All and Device.ReadWrite.All	Not supported.	GroupMember.ReadWrite.All and Device.ReadWrite.All
group	GroupMember.ReadWrite.All	Not supported.	GroupMember.ReadWrite.All
orgContact	GroupMember.ReadWrite.All and OrgContact.Read.All	Not supported.	GroupMember.ReadWrite.All and OrgContact.Read.All
servicePrincipal	GroupMember.ReadWrite.All and Application.ReadWrite.All	Not supported.	GroupMember.ReadWrite.All and Application.ReadWrite.All
user	GroupMember.ReadWrite.All	Not supported.	GroupMember.ReadWrite.All

In delegated scenarios, the signed-in user must also be assigned a supported Microsoft Entra role or a custom role with the microsoft.directory/groups/members/update role permission. The following roles are the least privileged roles that are supported for this operation, except for role-assignable groups:

• Group owners
• Directory Writers
• Groups Administrator
• Identity Governance Administrator
• User Administrator
• Exchange Administrator - only for Microsoft 365 groups
• SharePoint Administrator - only for Microsoft 365 groups
• Teams Administrator - only for Microsoft 365 groups
• Yammer Administrator - only for Microsoft 365 groups
• Intune Administrator - only for security groups

To add members to a role-assignable group, the app must also be assigned the RoleManagement.ReadWrite.Directory permission and the calling user must be assigned a supported Microsoft Entra role. Privileged Role Administrator is the least privileged role that is supported for this operation.

HTTP request

POST /groups/{group-id}/members/$ref
POST /groups/{group-id}/members/

Request headers

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

Request body

When using the /groups/{group-id}/members/$ref syntax, supply a JSON object that contains an @odata.id property with a reference by ID to a supported group member object type.

When using the /groups/{group-id}/members syntax, supply a JSON object that contains a members@odata.bind property with one or more references by IDs to a supported group member object type.

If using the directoryObjects reference, that is, https://graph.microsoft.com/v1.0/directoryObjects/{id}, the object type must still be a supported group member object type.

Response

If successful, this method returns a 204 No Content response code. It returns a 400 Bad Request response code when the object is already a member of the group or is unsupported as a group member. It returns a 404 Not Found response code when the object being added doesn't exist.
