In this context, OData Web APIs use Extensibility to allow custom applications access to server information in the Web Client. The OData Web APIs connect an embedded application to a server using Server Extensibility, which serves up information to display as a custom view in an iFrame in the Web Client.
The following example shows how the Web Client interacts with a server using Extensibility to create a tag. The Web Client interacts with the server using OData Web APIs. The custom service application reads any server events, applies any relevant logic, and interacts using a Web API.
OData Web APIs are being continually developed for integration to allow access for
custom applications in the Web Client using Extensibility. For more information on
server and client Extensibility, see Extensibility.
