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.
- Get the properties of a website using the REST API.
Endpoint URI
https://c986.sharepoint.com/_api/Web
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.
