Use HTTPie Desktop to reproduce a real API issue with multiple environments, authentication, request bodies, and a failing response. Save the requests, then hand them to another developer and see whether they can run the same sequence with their own credentials.
Inspect how secrets are stored and what gets synchronized or exported. Keep a command-line equivalent for automation and incident notes. An API client earns its place when it makes failures easier to reproduce without hiding important request details.
