i want to remove individual Link user by using one drive API in c#.

i have called MS graph API DELETE/me/drive/items/{item-id}/permissions/{perm-id} but it is removing al the external link user because permid is only one.

I want to delete permission for LINK external user individually.

Please Help.

Hello @Pradyut Sinha ,

You can use /beta, permission: revokeGrants, revoke access to a listItem or driveItem granted via a sharing link by removing the specified recipient from the link.

POST /drives/{drive-id}/items/{item-id}/permissions/{perm-id}/revokeGrants

Note: This functionality is only available for sharing links scoped to users.

GraphServiceClient graphClient = new GraphServiceClient( authProvider );

var grantees = new List<DriveRecipient>()
{
	new DriveRecipient
	{
		Email = "ryan@contoso.com"
	}
};

await graphClient.Me.Drive.Items["{driveItem-id}"].Permissions["{permission-id}"]
	.RevokeGrants(grantees)
	.Request()
	.PostAsync();

APIs under the /beta version in Microsoft Graph are subject to change. Use of these APIs in production applications is not supported.

Hope this helps.
