Paw comes with a large set of Dynamic Values, and you can write your own in jаvascript via Extensions. Compute hashes, authentication tokens, signatures, randomize data for testing, do some maths, or anything you want. Access data from previous responses, so you can send back whatever the server returned.
Build your custom code generator via Extensions. Either you are an API maker or consumer, Paw helps you build HTTP requests, inspect the server’s response and even generate client code. Paw is a full-featured and beautifully designed Mac app that makes interaction with REST services delightful.
