Steps Open Data Communication > Protocols > HTTP Client on the Functions palette to access the HTTP Client VIs Call the OpenHandle VI to create a client handle, optionally supplying credentials for authenticated requests Wire the client handle through the AddHeader VI to attach custom headers before each request Call the GET VI (or POST VI) with the target URL and client handle; it returns headers and body strings, defaulting to a 10000 ms timeout Parse the returned JSON body string with Unflatten From JSON, or use a REST toolkit for higher-level JSON handling Call the Close Handle VI to close the HTTP session and release the cookie file when finished Known gotchas GET/POST VIs return only raw header/body strings — no built-in JSON deserialization Default GET VI timeout is 10000 ms; slow instrument-backed APIs need it raised or set to -1 The client handle must be threaded through every call to preserve cookies/auth, and must be explicitly closed or the cookie file leaks
