Configuration of a REST message

A REST message contains the following elements:

• Endpoint: is the URL of the data to be retrieved, updated or deleted. The endpoint can be defined at the top level of the message, at the function level, or in the REST message workflow activity. The endpoint configured in the activity takes precedence over the other endpoints defined. 
• Headers: The HTTP headers in REST messages carry the information about the data format. They apply to all functions in that message unless the header is overridden  in the function definitions. Headers cannot be set in the REST message workflow activity. 
• Functions: REST message functions are the HTTP functions (put, post, get, delete) that interact with the data at the endpoint. Use the function definitions to override either the endpoint of header defined in the REST message. Each REST message workflow activity calls a single function to perform work on the endpoint.
