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.
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 least privileged roles 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.
If successful, this method returns a 204 No Content response code. It doesn't return anything in the response body. This method returns a 400 Bad Request response code when the object is already a member of the group. This method returns a 404 Not Found response code when the object being added doesn't exist.

Response
The following example shows the response.
HTTP/1.1 204 No Content
Example 2: Add multiple members to a group in a single request
This example shows how to add multiple members to a group with OData bind support in a PATCH operation. Up to 20 members can be added in a single request. The POST operation isn't supported. If an error condition exists in the request body, no members are added and the appropriate response code is returned.
