How to set the creationOptions when creating a Team? - microsoft-graph-api

Question

Using the Microsoft Teams Portal, I created a Group that came with Assignments and the Notebook tab. I want to create a similar Group programmatically.
I am using the Nuget Microsoft.Graph.Beta 4.0.1-preview to create Team for a School Classroom programmatically on Microsoft Teams.
However I noticed that the team created does not have the Assignments tab nor the Notebook.
Then I compared with a Team I created on the teams portal and found that the Team created manually on the Teams portal have this creationOptions on the class Group
"creationOptions": ["classAssignments", "ExchangeProvisioningFlags:2509"]
But on the group created by API it does not contain that.
The API also does not have the field creationOptions
How to add that information when creating it using the API?
Or
How can I add those options after the Team is created?
I also tried this:
var grupo = await graphClient.Groups.Request().AddAsync(new Group()
{
DisplayName = "Turma Dialética 2021",
Description = "Grupo da Turma Dialética 2021",
MailNickname = "f958e37c-f093-4177-8de4-2f86bfaba624",
MailEnabled = false,
SecurityEnabled = false,
GroupTypes = new string[] { "Unified" },
Visibility = "HiddenMembership",//
AdditionalData = new Dictionary<string, object>()
{
{"creationOptions", new List<string> { "classAssignments", "ExchangeProvisioningFlags:2509" } }
}
}
);
Which sends this JSON payload
{
"description": "Grupo da Turma Dialética 2021",
"displayName": "Turma Dialética 2021",
"groupTypes": [
"Unified"
],
"mailEnabled": false,
"mailNickname": "f958e37c-f093-4177-8de4-2f86bfaba624",
"securityEnabled": false,
"visibility": "HiddenMembership",
"#odata.type": "microsoft.graph.group",
"creationOptions": [
"classAssignments",
"ExchangeProvisioningFlags:2509"
]
}
But when I add this AdditionalData, then this Exception happens:
Microsoft.Graph.ServiceException: 'Code: Request_BadRequest Message: A value without a type name was found and no expected type is available. When the model is specified, each value in the payload must have a type which can be either specified in the payload, explicitly by the caller or implicitly inferred from the parent value. Inner error: AdditionalData: date: 2021-04-08T21:14:22 request-id: d3a0b0d3-5940-46d8-8188-56a1eaf5d350 client-request-id: d3a0b0d3-5940-46d8-8188-56a1eaf5d350`
If I add an # symbol in front of the word creationOptions. e.g. "#creationOptions" then no error when creating the Group, but then when I try to create the Team from this Group:
var team = new Microsoft.Graph.Team()
{
MemberSettings = new TeamMemberSettings()
{
AllowCreateUpdateChannels = false
},
MessagingSettings = new TeamMessagingSettings()
{
AllowUserEditMessages = false,
AllowUserDeleteMessages = false
},
FunSettings = new TeamFunSettings()
{
AllowGiphy = false
}
,
AdditionalData = new Dictionary<string, object>()
{
{"template#odata.bind", "https://graph.microsoft.com/v1.0/teamsTemplates('standard')"},
{"group#odata.bind", "https://graph.microsoft.com/v1.0/groups('" + grupo.Id + "')"}
}
};
graphClient.Teams.Request().AddAsync(team);
This error occurs:
Microsoft.Graph.ServiceException: 'Code: NotFound

Answer 1

You need to bind the correct template when POSTing to the /teams endpoint.
The educationClass template should create the right primitives in Teams and also set up the correct options under the hood in the Group.
From the POST /teams doc page:
POST https://graph.microsoft.com/beta/teams
Content-Type: application/json
{
"template#odata.bind": "https://graph.microsoft.com/beta/teamsTemplates('educationClass')",
"displayName": "My Class Team",
"description": "My Class Team’s Description"
}

Answer 2

The property doesn't appear to be defined in the metadata hence why it's not available in the SDK.
However, if you look at the definition for entity which group inherits from (via directory object), you'll find the additionalData property.
Setting the information there with something like the code snippet below should allow you to pass the desired information to the service.
AdditionalData = new Dictionary<string, object>()
{
{"#creationOptions", new List<string> { "classAssignments", "ExchangeProvisioningFlags:2509" } }
}
The # sign in front of the key is because this property is an instance annotation.
