Web services can be accessed from nearly every method to extend Microsoft Dynamics CRM, including the client. Microsoft Dynamics CRM Web services and other Web services can be called using asynchronous JavaScript and XML (AJAX) client-side code.

Web service calls are performed in client code using XMLHttp requests. The Web Service method and any necessary parameters are defined in XML and included in a SOAP Envelope. XMLHttp requests can be performed using the native support for the XMLHttpRequest Object provided in Windows Internet Explorer 7 or by using the ActiveXObject in earlier versions of Internet Explorer. Unless you are sure that all users are using Internet Explorer 7 it is best to use the ActiveXObject.

For more information about the XMLHttpRequest object, see msdn2.microsoft.com/en-us/library/ms535874.aspx.
