Minimal PowerShell script using Dev Proxy

Summary

This sample demonstrates the minimal setup to use Dev Proxy with a PowerShell script. It shows how to:

  • Configure Dev Proxy to intercept API requests
  • Mock API responses using the MockResponsePlugin
  • Run a PowerShell script through Dev Proxy using Invoke-RestMethod

The sample makes a single API call to JSONPlaceholder and returns a mocked response, demonstrating how Dev Proxy intercepts and replaces the real API call.
