Permissions

One of the following permissions is required to call this API. To learn more, including how to choose permissions, see Permissions.

Permissions to add an existing user, group, or device

Permission type Permissions (from least to most privileged)
Delegated (work or school account) AdministrativeUnit.ReadWrite.All
Delegated (personal Microsoft account) Not supported.
Application AdministrativeUnit.ReadWrite.All

Important

In delegated scenarios with work or school accounts, the signed-in user must be a member user or be assigned a supported Microsoft Entra role or a custom role with a supported role permission. Privileged Role Administrator is the least privileged role supported for this operation.

Permissions to create a new group

Permission type Permissions (from least to most privileged)
Delegated (work or school account) Group.ReadWrite.All and AdministrativeUnit.Read.All, Directory.ReadWrite.All
Delegated (personal Microsoft account) Not supported.
Application Group.Create and AdministrativeUnit.Read.All, Group.ReadWrite.All and AdministrativeUnit.Read.All, Directory.ReadWrite.All

Important

To create a new group in an administrative unit, the calling principal must be assigned at least one of the following Microsoft Entra roles at the scope of the administrative unit:

  • Groups Administrator
  • User Administrator

For app-only scenarios - apart from these roles, the service principal requires additional permissions to read the directory. These permissions can be granted via assignment of supported Microsoft Entra roles, such the Directory Readers role; or they can be granted via Microsoft Graph application permissions that allow reading the directory, such as Directory.Read.All.

Response

If successful, adding an existing object (using $ref) returns 204 No Content response code. It doesn't return anything in the response body.

When creating a new group (without $ref), this method returns a 201 Created response code and a group object in the response body. The response includes only the default properties of the group. You must supply the "@odata.type" : "#microsoft.graph.group" line in the request body to explicitly identify the new member as a group. A request body without the correct @odata.type returns a 400 Bad Request error message.
