How to Set Up a Proxy in Postman

Configuring Postman’s proxy settings

You can allow Postman to use your system's proxy settings or configure proxy settings manually to send requests through the Builder.

System proxy settings

If you have your proxy set up for Windows, macOS, or any other operating system, you can enable a system proxy in Postman’s settings by following these steps:

1. Navigate to settings (⚙️) > Settings > Proxy.

Enterprise Dedicated Datacenter Proxies

Proxy type: HTTP

Proxy server: a specific IP address (e.g., 1.2.3.4)

Proxy port: 60000

In the case of Enterprise Dedicated Datacenter Proxies purchased through sales, you'll have to choose an IP address from the acquired list. Please refer to our documentation for more details.

NOTE: To specify the SOCKS5 proxy type, you’ll have to find a workaround, as Postman doesn’t provide such an option.

Self-Service Dedicated Datacenter Proxies

Proxy type: HTTP or HTTPS

Proxy server: ddc.oxylabs.io

Proxy port: 8001

When using Self-Service Dedicated Datacenter Proxies purchased via the Oxylabs’ dashboard, you have to use the port number that indicates the sequential number of the IP address from the acquired list. For example, port 8001 will use the first proxy IP from your list. Please see our documentation for more information.

Shared Datacenter Proxies

Proxy type: HTTP

Proxy server: dc.pr.oxylabs.io

Proxy port: 10000

You can also use a country-specific entry. For example, if you enter dc.fr-pr.oxylabs.io under Proxy server and 42000 under Port, you’ll acquire a French exit node. For a complete list of country-specific entry nodes, please refer to our documentation.

4. Turn Proxy Auth ON and enter your Oxylabs sub-user’s credentials. Use the same credentials you entered to create a new sub-user in the Oxylabs dashboard.

NOTE: use Proxy Bypass to make exceptions. You can specify a list of hosts to be ignored by the custom proxy configuration.

You’re all set up. Now you can send your requests through a proxy in the Builder for enhanced security and anonymity.

Common Postman proxy issues 

Here are some of the most common proxy-related issues you could encounter using Postman:

• Missing proxy settings – update Postman to the latest version and check all of the proxy configuration settings mentioned in this guide.

• 407 proxy authentication error – specify your username and password either under system proxy or custom proxy settings and check the operating system’s proxy configuration.

• Missing postman-proxy-ca.crt – install OpenSSL and restart Postman.

Wrapping up

You can apply your system’s proxy settings to Postman to connect to any online service or to send HTTP(S) requests in the Builder. Also, you can configure a custom proxy for requests sent in the Builder separately from the system proxy.
