How to Work with Processes > Working with the HTTP/Web Services Processes Group

Process Purpose

The HTTP Request process is used to execute an HTTP request to a specific URL (call a web service).

When you add a process, you are required to define its settings. This occurs in the process's properties window which is displayed automatically after having added the HTTP request process.

If any subsequent edition is required, double-click the process to open its properties window and enter the necessary modifications.
