In this article, I’ll explain on how to post to Office 365 SharePoint Social Feed using .NET Client Object Model (CSOM).

Step1  Create a Console application by name ‘PublishToSocialFeed’

Step2 Add references to the following assemblies

Microsoft.SharePoint.Client
Microsoft.SharePoint.ClientRuntime
Microsoft.SharePoint.Client.UserProfiles

Step3 Add references to the following assemblies

using Microsoft.SharePoint.Client;
using Microsoft.SharePoint.Client.Social;

Step4

Create a Public Function by name ‘PublishPost’ and add the following snippet of code.

public static void PublishPost()
       {
           Uri oUri = new Uri(“https://yoursite.sharepoint.com”);

           Office365ClaimsHelper claimsHelper = new Office365ClaimsHelper(oUri, “youruserid@yoursite.onmicrosoft.com”, “yourpassword”);
          
           using (ClientContext oClientContext = new ClientContext(oUri))
           {
               oClientContext.ExecutingWebRequest += claimsHelper.clientContext_ExecutingWebRequest;

               SocialFeedManager oSocialFeedManager = new SocialFeedManager(oClientContext);
              
               //Create an instance of Social Data Item object
               SocialDataItem oSocialDataItem = new SocialDataItem();
               oSocialDataItem.ItemType = SocialDataItemType.Link;
               oSocialDataItem.Text = “Google”;
               oSocialDataItem.Uri = “http://google.com”;

               //Create an instance of Social Post Creation Data
               SocialPostCreationData oSocialPostCreationData = new SocialPostCreationData();
               oSocialPostCreationData.ContentText = “This is my first post”;

               oSocialFeedManager.CreatePost(null, oSocialPostCreationData);
               oClientContext.ExecuteQuery();

               Console.WriteLine(“Published a news feed”);
           }

       }
