The web services server comprising a plurality of transfer methods. The transfer methods comprises: i) a method for associating a remote transfer client with a session ID; ii) a method for providing to the remote transfer client the file transfer event parameters that are associated with the remote transfer client in response to receiving a method call from the remote transfer client; and iii) a method call for executing a file exchange with the remote transfer client in response to receiving a method call from the remote transfer client that includes the file transfer parameters.
