Introduction
SharePoint 2013 introduces a Representational State Transfer (REST) service that is comparable to the existing SharePoint client object models. This allows the developers to interact remotely with SharePoint data by using any technology that supports REST web requests. This means that developers can perform Create, Read, Update, and Delete (CRUD) operations from their apps for SharePoint, solutions, and client applications, using REST web technologies and standard Open Data Protocol (OData) syntax. In this article you will see the following:
- Create an app using the NAPA Tool in SharePoint 2013 Online.
- Cross-Domain Requests.
- Create a list using REST API.
Endpoint URI
https://c986.sharepoint.com/_api/web/lists
Note: If you are making cross-domain requests, then you need to add SP.AppContextSite(@target) and ?@target='<host web url>' to the endpoint URI.
HTTP Request
POST: To create entities such as lists and sites.
Create an app using NAPA Tool
- Navigate to the SharePoint 2013 Online site.
- Click on Site Contents in the quick launch bar.
- Click on “Napa” Office 365 Development Tools.

<div>
<p>
<b>Create List</b>
<br />
<input type="text" value="List Name Here" id="createlistname" />
<button id="createlistbutton">Create List</button>
</p>
</div>
</asp:content>
App.js
Replace the contents of App.js with the following:
'use strict';
var hostweburl;
var appweburl;
// Load the required SharePoint libraries.
$(document).ready(function () {
//Get the URI decoded URLs.
hostweburl = decodeURIComponent(
getQueryStringParameter("SPHostUrl"));
appweburl = decodeURIComponent(
getQueryStringParameter("SPAppWebUrl"));
//Assign events to buttons
$("#createlistbutton").click(function (event) {
createList();
event.preventDefault();
});
// Resources are in URLs in the form:
// web_url/_layouts/15/resource
var scriptbase = hostweburl + "/_layouts/15/";
// Load the js file and continue to load the page with information about the list top level folders.
// SP.RequestExecutor.js to make cross-domain requests
$.getScript(scriptbase + "SP.RequestExecutor.js");
});
// Utilities
// Retrieve a query string value.
// For production purposes you may want to use a library to handle the query string.
function getQueryStringParameter(paramToRetrieve) {
var params = document.URL.split("?")[1].split("&");
for (var i = 0; i < params.length; i = i + 1) {
var singleParam = params[i].split("=");
if (singleParam[0] == paramToRetrieve) return singleParam[1];
}
}
// Create a new custom list
function createList() {
var listName = document.getElementById("createlistname").value;
var executor;
// Initialize the RequestExecutor with the app web URL.
// Content Type Header is used to tell server what format data in the body contains.
executor = new SP.RequestExecutor(appweburl);
executor.executeAsync({
url: appweburl + "/_api/SP.AppContextSite(@target)/web/Lists?@target='" + hostweburl + "'",
method: "POST",
body: "{ '__metadata': { 'type': 'SP.List' }, 'BaseTemplate': 100,'Description': '" + listName + "', 'Title':'" + listName + "'}",
headers: {
"content-type": "application/json; odata=verbose"
},
success: createListSuccessHandler,
error: createListErrorHandler
});
}
// Success Handler
function createListSuccessHandler(data) {
alert("List Created successfully")
}
// Error Handler
function createListErrorHandler(data, errorCode, errorMessage) {
alert("Could not create a new list: " + errorMessage);
}
