1. What's it?

Breakpoint is a handy tool to help developers to edit the content of the Request and Response on the fly.
It's possible to set a breakpoint on both Request or Response.
If you're using Atlantis Framework, you could not use Breakpoint. Please consider using a normal proxy.

2. Main features

Breakpoint tool allows the developer to stop an ongoing Request or incoming Response to modify its data.

3. Breakpoint with Raw Message

4. Breakpoint by the Scripting Tool ✅

If you would like to do Breakpoint in an Automatic way, you should use the Scripting tools, which you can achieve the same result that Breakpoint can do, but in a flexible way by writing Javascript Code.
Please check out this Snippet Code to understand how to use Scripting for Breakpoint.
