Welcome to Ektron CMS400.NET API Online Help. This documentation helps you understand the Server Control API, Plug-in Extension API, .NET Assemblies and the Web Services API. Understanding these APIs allows you to enhance and extend your Ektron CMS400.NET site. 

• The Server Control API section explains the methods and properties available in code behind for Ektron's CMS400.NET Server Controls. Use these methods and properties when you want to customize the use of a server control beyond the drag and drop functionality provided.
• The Plug-in Extension API documentation details the methods and properties that are available when creating a custom plug-in. Plug-in Extensions expose event hooks in Ektron CMS400.NET. As a developer, you can utilize these event hooks in Visual Studio C# or VB.NET to create customized events for your site.
• The .NET Assemblies are used to access functionality typically provided in the Workarea. For example, adding content, deleting a user or retrieving information about a specific folder. By using the .NET Assemblies you can create custom functionality while keeping within the Ektron Inc. Business Rules.
• The Web Services API exposes many of the same methods as the .NET Assemblies for use with SOAP over HTTP.
