HTTP Clients

Configure Postman, Insomnia, and Paw to send HTTP/HTTPS traffic through Proxyman and troubleshoot certificate errors.

1. Problems​

Proxyman might not capture requests, or you might get an SSL error, when you send HTTP/HTTPS requests from some HTTP clients, such as Postman, Insomnia Rest, and Paw.

This page shows how to make them work with Proxyman.

2. Postman​

  1. Open Postman Settings
  2. In the General tab -> Uncheck the "SSL certificate verification" checkbox
  3. In the Proxy tab -> Check "Use the system proxy" and "Respect HTTP_PROXY, HTTPS_PROXY, and NO_PROXY environment variables".
Postman Settings, Proxy tab, with Use the system proxy checked

3. Insomnia Rest​

  1. Open Insomnia Preferences -> General tab
  2. Uncheck the "Validate certificates" checkbox
  3. Check "Enable proxy" and enter localhost:9090 in the HTTP Proxy and HTTPS Proxy text boxes.
Insomnia Preferences with Validate certificates unchecked and the proxy set to localhost:9090

4. Paw​

By default, the Paw app uses the system proxy configuration, so Proxyman works out of the box.

If you don't see any Paw traffic in Proxyman, please double-check:

  1. Open Paw Preferences.
  2. In the Network tab, make sure Proxy is set to System Proxy Configuration.
Paw Preferences, Network tab, with Proxy set to System Proxy Configuration
