According to link , an endpoint is defined in translated text below:

  

An endpoint is a connection point from where the HTML or dynamic files are exposed. Endpoints provide information needed to access a Webservice . The endpoint provides a reference or specification that is used to define a group or family of message-addressing properties and provide end-to-end message characteristics such as references to the origin and destination of the endpoints, as well as the identity of messages to allow uniform addressing of "independent" messages. The endpoint can be a PC, PDA, or point-of-sale terminal.

In your case, the endpoint is the WebService address itself that you want to access.
