    • Modify method, headers, body, query string, then click "Send".
    • Good for quick one-off edits.

  2. ModHeader extension (modify headers)

    • Install ModHeader from Chrome Web Store.
    • Create rules to add/modify/remove request or response headers.
    • Useful for testing auth, CORS, feature flags.

Tips

  • For HTTPS interception, you’ll need to install the proxy’s root certificate (only in test environments).
  • Use automated tools (Burp extensions, scripts) for repeatable tests.
  • Log changes and compare responses to avoid accidental damage.
