Web Services in SharePoint Online

SharePoint Online

In addition to the client object models, SharePoint Online provides web services for developers to access SharePoint data.

Available in SharePoint Online

SharePoint Online supports two Representational State Transfer (REST) interfaces that provides access to lists and libraries as a relational data service. In addition, SharePoint Online includes several default web services that enable developers to access SharePoint data remotely.

SharePoint Online also includes a REST interface that provides access to lists and libraries as a relational data service. A core concept of any RESTful interface is the resource, and in SharePoint Online, lists and items are represented as HTTP resources that can be addressed by remote URLs.

Operations in the SharePoint REST interface constitute a standard set of operations for RESTful web services. Read, Create, Update, and Delete operations are mapped directly to GET, POST, PUT, and DELETE HTTP verbs, which eliminates the need for intermediate layers between client and server.

The REST interface uses flexible URL conventions for querying data, which enable you to filter, sort, and select information from SharePoint lists directly from the browser. You can also retrieve information from SharePoint lists through multiple representations, including support for JSON, Atom, and AtomPub standards.

For more information, including example URLs that implement the REST interface, see SharePoint Foundation REST Interface.

Developers can also access the Excel Services REST API in SharePoint Online. This API enables developers to access workbook parts or elements directly through a URL. This allows for a flexible, secure, and simpler mechanism to access and manipulate Excel Services content.

The discovery mechanisms built into the Excel Services REST API also enable developers and users to explore the content of the workbook manually or programmatically by supplying an Atom feed that contains information about the elements that reside in a specific workbook. Some examples of the resources that you can access through the REST API are charts, PivotTables, and tables.

Using the Atom feed provided by the REST API is an easier way to get to the data you need. The feed contains traversable elements that enable any piece of code to discover what elements exist in a workbook.

For more information, see Excel Services REST API.

The following earlier ASP.NET web services are available in SharePoint Online. Although these and other external data connections are not available for use in sandboxed solutions, you can access them through client applications such as Microsoft Silverlight and ECMAScript (JavaScript, JScript).

Important note Important

Whenever possible, it is recommended that you use the new client-side object model to work remotely with SharePoint Online data, instead of using the legacy ASP.NET web services listed in Table 1.
