If you mean the request and response message pair, we call it "exchange" [0]. > It goes without saying that this is a hard requirement I have for any API client but sadly most ones I tried always lack some information somewhere. Both HTTPie Desktop and HTTPie CLI allow you to see the entire exchange. In the CLI, you can use the --verbose flag [0]. In the desktop app, there’s a “Request” tab. They both also support previewing the request without sending it. The CLI has --offline [1], and the Desktop has a live preview feature [2].
