Can anyone share the code and help me on how to follow and test if you are already following a site?

// Replace the siteUrl placeholder value before you run the code.
var siteUrl = "https://domain.sharepoint.com";
var followingManagerEndpoint;

// Get the SPAppWebUrl parameter from the query string and build
// the Following manager endpoint.
$(document).ready(function () {
    var appweburl;
    var params = document.URL.split("?")[1].split("&");
    for (var i = 0; i < params.length; i = i + 1) {
        var param = params[i].split("=");
        if (param[0] === "SPAppWebUrl") appweburl = param[1];
    }
    followingManagerEndpoint = decodeURIComponent(appweburl) + "/_api/social.following";
    isFollowed();
});

// Check whether the current user is already following the site.
// The request body includes a SocialActorInfo object that represents
// the specified item. 
// The success function reads the response from the REST service and then
// toggles the user's following status by calling the appropriate method.
function isFollowed() {
    $.ajax( {
        url: followingManagerEndpoint + "/isfollowed",
        type: "POST",
        data: JSON.stringify( {

  • Thaks it's almost complete.. but i'm having trouble with this error 'Uncaught TypeError: Cannot read property 'IsFollowed' of undefined' – Looytawon Sep 9 '15 at 15:19
  • When are you facing this error? – Taran Goel Sep 9 '15 at 15:23
  • i tried to view the jsonObject. but it showing like this :<!DOCTYPE html> <html lang="en" xmlns="w3.org/1999/xhtml" data-ng-app="alphaKanban"> <head> <title>app</title> <script type="text/javascript" src="../Scripts/jquery-1.9.1.min.js"></script> <script type="text/javascript" src="../Scripts/bootstrap.min.js"></script> <script type="text/javascript" src="../Scripts/angular.min.js"></sc </html> what do you think the problem? – Looytawon Sep 9 '15 at 15:42
  • but the post process was successfully executed XHR finished loading: POST "uling-e71b8136182c04.sharepoint.com/sharepointapp". – Looytawon Sep 9 '15 at 15:43
  • @Looytawon The above answer satisfies the need your question, though I'll really suggest you to ask a different question on how to call rest api in an app. It will help you better :) – Taran Goel Sep 14 '15 at 4:52

You can use the endpoint http://<siteCollection>/<site>/_api/social.following/isfollowed

You should take a look at this very detailed MSDN article: Following people and content REST API reference for SharePoint 2013.

we have ready made examples on MSDN to follow , sites, documents, tags and people REST Social API.

  • i already tried the isfollowed REst api code .. the post was a success but when i tried to view the json form of the response i was confused when it returns hmtl tags?? wwooaahh?? what the problem? – Looytawon Sep 9 '15 at 15:51
  • are you using a SharePoint app or you executing the code in sharepoint site itself? – sekhar Sep 9 '15 at 15:54
  • Im building a sharepiont app specifically a sharepoint hosted app ! – Looytawon Sep 9 '15 at 15:56
  • Ok, you said you are getting the HTML response. That means something wrong with your endpoint url formation. you might be getting "pagenotfound.aspx page markup in response. Do one thing, open the page in Chrome, copy the response you are getting in REST call. Open browser dev tools(F12). goto elements section, right click on html tag->edit as html. replace the whole markup with your response text in the editable box, click somewhere else on the browser document area. You will see the page that you are getting in the response. reply here what the page has. – sekhar Sep 9 '15 at 16:10
  • i exactly recieving response like this i tried to view the jsonObject. but it showing like this :<!DOCTYPE html><html lang="en"xmlns="w3.org/1999/xhtml";data-ng-app="alphaKanban"><head><title>app</title><script type="text/javascript" src="../Scripts/jquery-1.9.1.min.js"></script><script type="text/javascript" src="../Scripts/bootstrap.min.js"></script> <script type="text/javascript" src="../Scripts/angular.min.js"></sc </html> in the jsonObject but i think the post request was successful coz it shows 'XHR finished loading: POST "uling-e71b8136182c05.sharepoint.com/sharepointkanbo. – Looytawon Sep 9 '15 at 16:48
