How can I receive a response message status in HTTP client tool?

Hi guys 😊

I’m testing an HTTP client tool and when I try to send a message, XI receives it with flag ok, but also with a red triangle “Acknowledgement not possible”… and when I check in the HTTP client tool nothing appears as a result (I would like to know how can I receive something like OK code 200, something to guarantee that my message was received on XI)!!! How can I send this Acknowledgement from XI to HTTP client tool???

Scenario: HTTP client tool <->XI. (Asynchronous interface)

This is possible with an asynchronous interface?

Thanks in advance.

Cheers,

Ricardo.
