Clients invoke business processes to perform one or more operations. Business Processes expose their functionality through methods.
Client Request nodes represent the points in a business process at which a client invokes a method on the business process and possibly sends input to the business process. The names you assign to methods on Client Request nodes correspond to the names of the methods that are exposed via the Web Services Description Language (WSDL) when you make your business process available as a Web service.
Note: The nodes in a business process are always communicating asynchronously with clients, except for when you invoke a Start node of a business process by using the Client Request with Return option or configure the starting event on a Message path to wait for a Client Request with Return. To learn more about using the Client Request with Return node, see Client Request with Return Start (Synchronous).
Client Response nodes represent the points in a business process at which business processes send messages to clients.
This section describes how to add nodes to your business process and design the interactions of business processes with clients. It includes the following topics:
