Follow documents, sites, and tags by using the REST service in SharePoint
Create SharePoint-hosted apps that use the REST service to follow content (documents, sites, and tags) and to get followed content.
How do I use the SharePoint REST service to follow content?
SharePoint users can follow documents, sites, and tags to get updates about the items in their newsfeeds and to quickly open followed documents and sites. You can use the SharePoint REST API in your app or solution to start following content, stop following content, and get followed content on behalf of the current user.
The following REST resources are the primary API for Following Content tasks:
SocialRestFollowingManager provides methods for managing a user's list of followed actors.
SocialActor represents a document, site, or tag that the server returns in response to a client-side request.
SocialActorInfo specifies a document, site, or tag in client-side requests to the server.
SocialActorType and SocialActorTypes specify content types in client-side requests to the server.
To perform Following Content tasks by using the REST API, you send HTTP GET and HTTP POST requests to the REST service. REST endpoint URIs for Following Content tasks begin with the SocialRestFollowingManager resource ( <siteUri>/_api/social.following) and end with one of the following resources:
follow to start following a document, site, or tag
stopfollowing to stop following a document, site, or tag
isfollowed to find out whether the user is following a specific document, site, or tag
my/followed to get followed documents, sites, and tags
my/followedcount to get the count of followed documents, sites, and tags
Note
You also use these endpoints for Following People tasks, but the followers and suggestions resources available from SocialRestFollowingManager only support following people, not content. For more information about how you can use SocialRestFollowingManager, see Follow content in SharePoint and Follow people in SharePoint.
Prerequisites for creating a SharePoint-hosted app that manages followed content by using the SharePoint REST service
This article assumes that you create the SharePoint Add-in by using Napa on an Office 365 Developer Site. If you're using this development environment, you've already met the prerequisites.
Note
Go to Set up a development environment for SharePoint Add-ins on Office 365 to sign up for a Developer Site and start using Napa.
If you're not using Napa on an Office 365 Developer Site, you'll need to meet the following prerequisites before you can deploy the SharePoint Add-in:
A SharePoint development environment that is configured for app isolation. If you're developing remotely, the server must support sideloading of apps or you must install the app on a Developer Site.
The My Site host configured, with a personal site created for the current user.
Visual Studio 2012 or Visual Studio 2013 with Office Developer Tools for Visual Studio 2013.
Sufficient permissions for the logged-on user:
Local administrator permissions on the development computer.
Manage website and Create Subsites user permissions to the SharePoint site where you're installing the app. By default, these permissions are available only to users who have the Full Control permission level or who are in the site Owners group.
You must be logged on as someone other than the system account. The system account does not have permission to install the app.
Note
See Set up an on-premises development environment for SharePoint Add-ins for guidance about on-premises setup (including how to disable the loopback check, if necessary).
Create the SharePoint Add-in project
On your Developer Site, open Napa, and then choose Add New Project.
Choose the App for SharePoint template, name the project, and then choose the Create button.
Set the permissions for your app:
Choose the Properties button at the bottom of the page.
In the Properties window, choose Permissions.
In the Content category, set Write permissions for the Tenant scope.
In the Social category, set Read permissions for the User Profiles scope.
Close the Properties window.
Expand the Scripts node, choose the App.js file and replace its contents with the code from one of the following scenarios:
To run the app, choose the Run Project button at the bottom of the page.
In the Do you trust page that opens, choose the Trust It button. The app page opens and runs the code. To debug the page, choose the F12 key and then choose App.js on the Script tab.
Code example: Start following and stop following a document by using the SharePoint REST service
The following code example represents the contents of the App.js file and shows how to:
Get the app web URI from the query string and construct the
<siteUri>/_api/social.followingendpoint URI.Build and send a POST request to the
isfollowedendpoint to find out whether the current user is already following a specified document.Build and send a POST request to the
followendpoint to start following the document.Build and send a POST request to the
stopfollowingendpoint to stop following the document.Read the JSON response returned by the
isfollowedrequest and thefollowrequest. (Thestopfollowingrequest doesn't return anything in the response.) See Example JSON responses.
Before you run the code, you'll need to upload a document and change the placeholder value for the documentUrl variable to the document's URL.
// Replace the documentUrl placeholder value before you run the code.
var documentUrl = "https://domain.sharepoint.com/Shared%20Documents/fileName.docx";
var followingManagerEndpoint;

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 document.

Code example: Start following and stop following a site by using the SharePoint REST service
The following code example represents the contents of the App.js file and shows how to:

Before you run the code, change the placeholder value for the siteUrl variable to match the site that you want to follow. Use the format http://server/siteCollection/site for a site in a site collection. You can follow a site from any page or library in that site. If the site uses a template that doesn't support following (like the My Site host or a personal site), you'll get an UnsupportedSite error (error code 10).

Code example: Start following and stop following a tag by using the SharePoint REST service
The following code example represents the contents of the App.js file and shows how to:
Get the app web URI from the query string and construct the
<siteUri>/_api/social.followingendpoint URI.Build and send a POST request to the
isfollowedendpoint to find out whether the current user is already following a specified tag.Build and send a POST request to the
followendpoint to start following the tag.Build and send a POST request to the
stopfollowingendpoint to stop following the tag.Read the JSON response returned by the
isfollowedrequest and thefollowrequest. (Thestopfollowingrequest doesn't return anything in the response.) For more information, see Example JSON responses.
Before you run the code, change the placeholder value for the tagGuid variable to the GUID of an existing tag. The taxonomy API that you use to retrieve a tag from the HashTagsTermSet doesn't have a REST interface, so you have to use the .NET client object model or the JavaScript object model. See How to get a tag's GUID based on the tag's name by using the JavaScript object model for an example.
// Replace the tagGuid placeholder value before you run the code.
var tagGuid = "19a4a484-c1dc-4bc5-8c93-bb96245ce928";

Example JSON responses for Following Content requests
By default, the REST service returns responses that are formatted by using the Atom protocol, but you can request the JSON format by using an HTTP Accept header (for example: "accept":"application/json;odata=verbose"). The response data is returned as a string, and you can use the JSON.stringify function and JSON.parse function to convert the string into an object, as shown in the previous code examples.
To troubleshoot an error returned by the REST service, in debug mode, look at the responseText property, as shown in the requestFailed callback functions in the previous examples. You can also get the correlation ID for the ULS server log from a network sniffer or HTTP debugger, such as Fiddler. The correlation ID is the same as the request ID in the HTTP response.
Example response for the Follow endpoint
In response to client-side requests to the follow endpoint, the REST service returns a SocialFollowResult value that represents whether the Follow request succeeded.
The following response represents the AlreadyFollowing status.
{"d":{"Follow":1}}
Table 1 shows SocialFollowResult status codes and their values.
Table 1. SocialFollowResult codes and values
| Status code | Value |
|---|---|
| 0 | OK. The current user is now following the actor. |
| 1 | AlreadyFollowing. The current user is already following the actor. |
| 2 | LimitReached. The request failed because an internal limit was reached. |
| 3 | InternalError. The request failed due to an internal error. |
Note
The REST service doesn't return a response for the StopFollowing request. It returns {"d":{"StopFollowing":null}}.
Example response for the IsFollowed endpoint
In response to client-side requests to the isfollowed endpoint, the REST service returns a bool value that represents whether the current user is following the specified actor.
The following response indicates that the current user is not following the specified document, site, or tag.
{"d":{"IsFollowed":false}}
Example response for the My/Followed endpoint
In response to client-side requests to the my/followed endpoint, the REST service returns an array of SP.Social.SocialActor objects that represent documents, sites, and tags that the current user is following.
The following response represents a followed document, site, and tag. The request specifies the types of content to include.

Example response for the My/FollowedCount endpoint
In response to client-side requests to the my/followedcount endpoint, the REST service returns an Int32 value that represents the total count of specified actor types that the current user is following.
The following response represents a count of three followed documents, sites, and/or tags. The request specifies the types of content to include.
{"d":{"FollowedCount":3}}
