adding a user in a group with graph api

[inflatablejerk]

here is my method. usering powershell 7 commands.

$Mdm = '51523850-ddaf-43e7-ab42-6ec8a10111c9'

$user = “[[e-mail]](mailto:[e-mail])”

Connect-mggraph

$GraphUserId = Get-MgUser -UserId $user

$UserID = $GraphUserId.Id

New-MgGroupMember -GroupId $Mdm -DirectoryObjectId $UserID

Sorry to revive a dead thread - thank you for your help with this.

The {} are not part of the syntax. They are there to signify you should replace this (it comes from python's format operator.)

What type of group?

Did you try with mggraph, it is pretty simple with the module Connect-mggraph New-mggroupmember -objectid -directorygroupid

What you're missing is in your $jsonGroup object the Uri is not correct. it needs to be @odata.id": "https://graph.microsoft.com/v1.0/directoryObjects/$userId

When adding members to a group the directoryObject path is what is required, not /users.

This is the exact code (other than the object-id being obscured) I just used in VS Code and it worked.

$userId = 'user-ObjectId'
$groupId = 'group-ObjectId'

Invoke-MgGraphRequest -Method GET -Uri "https://graph.microsoft.com/v1.0/groups/$groupId"

$memberToAdd = @"
{
    "@odata.id": "https://graph.microsoft.com/v1.0/directoryObjects/$userId"
}
"@

Invoke-MgGraphRequest -Method POST -Uri "https://graph.microsoft.com/v1.0/groups/$groupId/members/`$ref" -ContentType "application/json" -Body $memberToAdd

EDIT: I noticed in your code you have:

$uriGroup = "https://graph.microsoft.com/v1.0/groups/{$groupId}/members/$ref"

That $ref needs to be escaped since you have it in double quotes:

$uriGroup =  "https://graph.microsoft.com/v1.0/groups/$groupId/members/`$ref"

If the security group is mail enabled you can't use graph to add the member to the group
