The HTTP Client Node allows the user to send HTTP requests to a selected HTTP server. All configurations are made in the Node or in the Attributes section. There are several methods that the user can select from to perform different HTTP requests. These are: GET, POST, PUT, HEAD, and DELETE.
Scope: Project, Scene.
Depending on the Method selected, the Attributes and Inputs might change. However, there are several common Attributes, Inputs, and Outputs between the many HTTP Methods.

POST sends data, in this case the information from the Request Body, to the desired server as per the HTTP protocol.
