What is Postman?
Configuration requirements
Before you start, ensure you have:
- Postman desktop app installed (Windows, macOS, or Linux)
- A valid Decodo account
- Your proxy credentials (host, port, username, password)
Step-by-step Postman proxy setup
Step 1: Get your proxy credentials
- Log in to the Decodo dashboard.
- Choose Residential under Proxies.
- Navigate to Proxy setup.
- Choose your target country (e.g., Japan).
- Copy the Proxy address (gate.decodo.com), port (10001), username, and password.
Step 2: Access proxy settings
- Open Postman.
- Click the Settings icon in the top-right header.
- Select Settings from the dropdown menu.
- Navigate to the Proxy tab.
Step 3: Configure custom proxy
- Toggle on Use custom proxy configuration.
- Use proxy for – check both HTTP and HTTPS.
- Proxy server – enter the host name (gate.decodo.com) and port (7000).
- Toggle on Proxy auth.
- Username. Enter your username.
- Password. Enter your password.
- Close the Settings window (it will save automatically).
Step 4: Verify connection
- Click the + icon to create a new request.
- Set the method to GET.
- Enter URL: https://ip.decodo.com/ip (This endpoint returns the caller's IP).
- Click Send.
- The JSON response should display your Decodo proxy IP, confirming the traffic is routed correctly.
Troubleshooting Postman connection issues
"Error: connect ETIMEDOUT"
This usually means the proxy host or port is incorrect. Double-check for spaces. Also, ensure your corporate firewall allows outbound connections on port 7000.
SSL verification errors
If developing with self-signed certificates or proxying HTTPS, you may need to disable SSL certificate verification in the General tab of Postman Settings.
System proxy conflict
Ensure the Use System Proxy toggle in the Proxy settings is turned off. If it's on, Postman might ignore your custom configuration and use your OS settings instead.
Why use Decodo residential proxies with Postman
Test geo-dependent logic
Ensure your API returns the correct currency, language, or content based on the user's location. Switch your proxy IP to the UK, Germany, or Brazil to validate your backend's localization logic instantly.
Verify rate limiting
Test how your API handles traffic spikes. By rotating your residential IP with every request, you can simulate multiple unique users hitting your endpoint simultaneously to verify your rate-limiting rules.
Debug CDN latency
Check the performance of your API from a "real user" perspective. Connect via a residential IP in a specific city to measure the actual latency your users experience when hitting your CDN edge servers.

Frequently asked questions
Can I set a proxy for a single request only?
Postman's global settings apply to all requests. However, you can write a "pre-request script" to dynamically set proxy environment variables. For scoped testing, developers often use Postman environments to toggle proxy variables.
Does Postman support SOCKS5?
Postman currently has limited native support for SOCKS5 proxies in its GUI settings (it focuses on HTTP/HTTPS). If you strictly need SOCKS5, use a system-level proxy or simply use the HTTP protocol for your API tests, as it covers REST/GraphQL/SOAP perfectly.
Can I use this for Newman (CLI)?
Yes. When running collections via Newman command line, simply pass the proxy flag: newman run collection.json --proxy-url http://user:[email protected]:7000.
