httpie is yummy
If you are developing REST APIs you need a client to test them.
If you are on Linux you use curl.
If you are on Windows, you can look for a Chrome or Firefox plugin (I used poster a while ago) but I recommend you to use httpie
httpie is exactly like curl.
To install it do:
pip install httpie
This will add an http binary and now to use it you just do it like this:
http -a john:psw123 POST http://127.0.0.1/books/ title=something
http GET htp://127.0.0.1:800/books/1/
and so on…
