Add-in Code Snippet:

The following code snippet is used in SharePoint Add-in to get the allow rss feed property of a SharePoint web.

// Load the js files and continue to the successHandler
$.getScript(scriptbase + "SP.RequestExecutor.js", execCrossDomainRequest);


// Function to prepare and issue the request to get
//  SharePoint data
function execCrossDomainRequest() {

    // Initialize the RequestExecutor with the add-in web URL.
    var executor = new SP.RequestExecutor(appweburl);

    // Issue the call against the add-in web.
    // To get the AllowRssFeeds property using REST we can hit the endpoint:
    //      appweburl/_api/web?select=AllowRssFeeds&@target=hostweburl
    // The response formats the data in the JSON format.
    executor.executeAsync(
        {
            url: appweburl + "/_api/SP.AppContextSite(@target)/web?$select=AllowRssFeeds&@target='" + hostweburl + "'",
            method: "GET",

            },
            success: successHandler,
            error: errorHandler
        }
    );
}

// Function to handle the success event.
// Prints the host web's title to the page.
function successHandler(data) {
    var jsonObject = JSON.parse(data.body)
    //jsonObject.d.AllowRssFeeds returns true if enabled otherwise it returns false
    console.log('Rss feeeds Enabled on this site: ' + jsonObject.d.AllowRssFeeds);
    if(jsonObject.d.AllowRssFeeds)
    $('#message').html('Rss feeds enabled on this site.');
    else
    $('#message').html('Rss feeds disabled on this site.');

}

function errorHandler(data, errorCode, errorMessage) {
    console.log("Could not complete cross-domain call: " + errorMessage);
}
