oEscal opened a new issue, #3936:
URL: https://github.com/apache/incubator-kie-kogito-runtimes/issues/3936

   ### Description
   
   Currently, the behavior of REST custom functions is that if the requested 
endpoint returns an HTTP response with a code between 200 and 300, the function 
will return the response body as JSON.
   However, this is a bit constraining for developers. First, if the endpoint 
returns an error status code, the workflow throws an error and fails. But I, as 
a developer, might want to have some logic around getting error responses. For 
instance, if an endpoint responds with a 400 status code, I might want to run a 
function that handles the error.
   Response headers are entirely ignored. However, similar to the status code, 
I might want to have logic around response headers' values. I might also want 
to send them as headers or even in the request body to the following function.
   
   Ultimately, I think it should be up to developers to decide what to do with 
headers and status codes if they choose to do so.
   
   ### Implementation ideas
   
   First, I think it is a good idea to maintain the current behavior as the 
default for backward compatibility. Therefore, we can divide this feature into 
three options: `the function failing when it gets an error status code` 
(default to `true`); `return headers` (default to `false`), and `return status 
code` (default to `false`). Similar to the host or port, these values could 
then be controlled by related properties. For instance:
   - function failing when it gets an error status code: 
`kogito.sw.functions.<function name>.fail_on_status_error`
   - return headers: `kogito.sw.functions.<function name>.return_headers`
   - return status code `kogito.sw.functions.<function name>.return_status_code`
   
   Then, depending on whether the properties are set or not, the function 
returns the headers and status code and does not fail when getting a status 
code below 200 or bigger than 300.
