The Fast Connect 3 Credential Insertion API provides an interface that supplies user credentials to the single sign-on (SSO) feature of Citrix Receiver for Windows 4.2 and later. Using this API, Citrix partners can provide authentication and SSO products that use StoreFront or the Web Interface to log users on to virtual applications or desktops and then disconnect users from those sessions.
The system requirements and prerequisites for the API are the same as those for Receiver. Note that XenDesktop 7 does not support the Web Interface.
The Fast Connect 2 API is still available, but can be used only with Receiver for Windows 3.4.
