Postman Proxy Setup Tutorial: Configure and Test Your API Requests

Overview


This article explains how to configure Trusted Proxies's proxy service in Postman, a popular API development and testing tool. By routing your API requests through our proxy, you can test geo-targeted APIs, monitor traffic, or anonymize your requests.

 

Prerequisites

  • An active proxy account with Trusted Proxies
  • Proxy server address and port (e.g., shp-testuser-us-v00001.tp-ns.com:27281)
  • Proxy username and password (if authentication is required)
  • Postman installed on your computer

 

Step 1:  Using System Proxy Settings in Postman


If you have already configured a proxy on your Windows, macOS, or other operating system, you can enable Postman to use these system proxy settings:

Open Postman.
Go to Settings (⚙️) > Settings > Proxy.
Turn on Use System Proxy.
If your system proxy requires authentication, activate the This proxy requires authentication option under Default Proxy Configuration and enter your Trusted proxy user credentials.

 

 

Step2:  Setting Up Proxy Directly in Postman


Alternatively, you can manually configure your proxy within Postman:

 

Open Settings (⚙️) > Settings > Proxy 

 

Turn on Use custom proxy configuration

 

 


Enter your proxy server and port (e.g., shp-testuser-us-v00001.tp-ns.com:27281).
If your proxy requires authentication, enable Proxy Auth and enter your username and password.
Click Save Settings.


Step 3: Test Your Proxy


Create a new request in Postman (e.g., https://httpbin.org/ip).

 

 

Send the request.
If configured correctly, the response should show the IP address of the proxy server, not your local IP.

 


Troubleshooting


Connection Errors: Double-check your proxy address, port, and credentials.


Authentication Issues: Ensure your username and password are correct and that your account is active.


Bypass Proxy for Local Addresses: You can configure Postman to bypass the proxy for specific hosts in the Proxy settings.
