Create a file anywhere ending in .httpie, such as Request.httpie
Add HTTPie commands to it:
http -v PUT httpbin.org/put API-Key:foo hello=world
// Separate commands with commented lines (//)
http DELETE example.org/todos/7
// Request a Google search
http www.google.com search=='HTTPie logo' tbm==isch
// Use multiple lines for a single command
http www.google.com
search=='HTTPie logo'
tbm==isch
Click the Send request button that appears above each command in the file, and the command will execute in the Terminal.
