Setting up a proxy server in Postman

What is Postman?

Postman is a program that helps developers design, build, and test APIs (Application Programming Interfaces). It provides a convenient interface for creating HTTP requests and interacting with APIs. With Postman, developers can send requests, view responses, and test various API endpoints and parameters. It is widely used in the software development industry to simplify the API development and testing process.

When using Postman to design, build, and test APIs, you may need to configure a proxy server for your requests. A proxy acts as an intermediary between Postman and the destination server, providing an additional layer of security and handling HTTP(S) responses on your behalf.

Configuring proxy settings in Postman

To configure proxy settings in Postman, you have two options: use your system's proxy settings, or configure proxy settings in Postman manually.

Using system proxy settings:

1. Download and open Postman and go to settings (⚙️) > Settings > Proxy.
   
   
2. If your system proxy requires authentication, you can enable the "This proxy requires authentication" option in the "Default proxy configuration" section. Make sure you enter your Stableproxy user credentials, the same credentials you used when creating the user in the Stableproxy dashboard.
3. After making changes, click the Save button and restart Postman.
   

Builder can now send requests through a proxy server.

To use the system proxy for Postman Builder queries, follow these steps:

1. Go to the section "Proxy configurations for sending requests" and enable the option "Use system proxy".
2. Optionally, you can enable the "Respect environment variables" option to use the system settings for proxy types.
   NOTE: Make sure "Add your own proxy configuration" is disabled so that Postman doesn't ignore the system proxy and use your own proxy instead.
   

That's all it takes! With these simple instructions, you can easily configure proxy servers for specific applications, tailoring their use to your individual needs. Enjoy personalized web browsing with ease.

Custom proxy settings

To use Stableproxy to make HTTP(S) requests to Postman Builder, follow these steps:

1. Go to settings (⚙️) > Settings > Proxy.
2. Enable the "Add your own proxy configuration" option.
3. Configure the proxy settings by specifying the required details such as proxy type, host, port, username and password.
4. Fill in the proxy settings based on the data in your control panel
   
   
5. Enable Proxy Authorization and enter your Stableproxy subuser credentials. 
   NOTE: You can use Bypass Proxy to specify a list of hosts to be ignored by the custom proxy configuration.

You're all set! You can now send your requests through a proxy in the builder to enjoy increased security and anonymity
