Postman Interceptor
🔍 Security Report Available View on Chrome Web StoreChrome will indicate if you already have this installed.
Blocks requests from any website and sends them to Postman Client, allowing developers to capture and analyze traffic without leaving their browser. Lets you inspect and debug HTTP requests in real-time, ideal for web developers and testers who need to examine request data. Brings the power of Postman's API testing tools directly into your Chrome browser.
Overview
Postman Interceptor helps you send requests which use browser cookies through the Postman app.
It can also send headers which are normally restricted by Chrome but are critical for testing APIs. The Interceptor makes this process painless. Something that would have required a proxy earlier can now be achieved without any installation steps or extra configuration.
