add "assignedBy" and "createdBy" in PlannerTask

Manoj S Pant

We are using application permission, and need to create a planner task.
All things are working fine, but we need to add "assignedBy" and "CreatedBy" users (We have the object Id's of users).

By default when we are creating a Planner task with ClientSecretCredential[appication permission], it passes application id(Client Id of Azure AD registered application ) "assignedBy" and "CreatedBy", but we need to pass the user object Id also, So then in planner,
It shows "assigned to" and "assigned by" user also.

Note:

Application permission and Microsoft.Graph V5.3.0

Below is the code which we are using:

string tenentId = "xxxxxxxx";
string clientId = "xxxxxxx";
string clientScret = "xxxxxxxxx";

// Application permission 
ClientSecretCredential clientSecretCredential = new ClientSecretCredential(tenentId, clientId, clientScret);
GraphServiceClient gsClient = new GraphServiceClient(clientSecretCredential);
var plannerAssignments = new PlannerAssignments();

// Add assign to
var plannerAssignment = new PlannerAssignment();
plannerAssignment.OrderHint = " !";
plannerAssignment.OdataType = "#microsoft.graph.plannerAssignment";             
plannerAssignments.AdditionalData.Add("af0c0624-3138-446d-9d9e-f86159890745", plannerAssignment);
var requestBody = new PlannerTask
{
    PlanId = "wOJWGexB0U-a3n-LZ9nX_2UAD-xT",
    BucketId = "RWBdSfn0h0OsFR9XBksEKmUAIgaG",
    Title = "Update client list 100",
    Assignments = plannerAssignments,
    CreatedBy = new IdentitySet() { User = new Identity() {  DisplayName= "Adele Vance", Id = "ba8ebefe-fdb9-4ef6-b6c0-80c745d12a0e", OdataType = "#microsoft.graph.identitySet" } }
};
var plannerTaskRes = await gsClient.Planner.Tasks.PostAsync(requestBody);

To add "assignedBy" and "createdBy" users when creating a Planner task using application permissions, you need to modify the request payload and include the object Id of the users. Here's an example of how you can modify the payload:
```
POST https://graph.microsoft.com/v1.0/planner/tasks

{
  "planId": "",
  "bucketId": "",
  "title": "New Task",
  "startDateTime": "2023-04-01T08:00:00Z",
  "dueDateTime": "2023-04-01T17:00:00Z",
  "assignedTo": {
    "@odata.type": "#microsoft.graph.plannerAssignment",
    "orderHint": " !",
    "assignedUserId": ""
  },
  "assignedBy": {
    "@odata.type": "#microsoft.graph.plannerAssignment",
    "orderHint": " !",
    "assignedUserId": ""
  },
  "createdBy": {
    "@odata.type": "#microsoft.graph.identitySet",
    "application": {
      "@odata.type": "#microsoft.graph.identity",
      "id": ""
    },
    "user": {
      "@odata.type": "#microsoft.graph.identity",
      "id": ""
    }
  }
}
```
In the payload, replace , , , and with the appropriate values. The assignedTo and assignedBy properties use the plannerAssignment type, which includes an assignedUserId property to specify the user's object Id. The createdBy property uses the identitySet type, which includes both the application and user identities.

Make sure to include the appropriate permissions in your Azure AD application registration for creating Planner tasks with user and application identities.

Hello @Tuhin Paul,

Thanks for the reply.

1. Over my side inside the PlannerTask object, not able to get the property "CreatedById " and "AssignedById ".

2. I have the CreatedBy property in the Task planner, but I think it is over application permission, so it is not taking the user details which we are passing in the createdBy property.

CreatedBy = new IdentitySet() { User = new Identity() { DisplayName= "Adele Vance", Id = "ba8ebefe-fdb9-4ef6-b6c0-80c745d12a0e", OdataType = "#microsoft.graph.identitySet" } }

// Create a new Planner task
var plannerTask = new PlannerTask
{
    PlanId = "wOJWGexB0U-a3n-LZ9nX_2UAD-xT",
    BucketId = "RWBdSfn0h0OsFR9XBksEKmUAIgaG",
    Title = "Update client list 100",
    CreatedById = "ba8ebefe-fdb9-4ef6-b6c0-80c745d12a0e", // Set the CreatedBy user object ID
    AssignedById = "ba8ebefe-fdb9-4ef6-b6c0-80c745d12a0e", // Set the AssignedBy user object ID
};

// Create a new GraphServiceClient with application permission
var client = new GraphServiceClient(new ClientCredentialProvider(clientId, clientSecret, tenantId));

// Create the Planner task
var createdTask = await client.Planner.Tasks.Request().AddAsync(plannerTask);

The CreatedById and AssignedById properties are set to the user object ID "ba8ebefe-fdb9-4ef6-b6c0-80c745d12a0e". You can replace these values with the actual user object IDs you want to use.

You can use the Microsoft.Graph.Core library and set the CreatedById and AssignedById properties on the PlannerTask object.
