Katalon Studio

Web services are specific services that can be published and called over the Internet by client applications. Katalon Studio supports functional testing of web services. This topic provides an overview of how to setup for web service testing.

Proxy Settings

Proxy can be configured at: Preferences > Proxy. The setting affects both WebUI and WebService test execution.


Field Description
Proxy Option Specify how Katalon Studio will deal with proxy

  • No Proxy: do not apply any proxy setup
  • Use system proxy configuration: proxy setup by local machine will be utilized
  • Manual proxy configuration: manually define information for proxy
Proxy Server Type Specify the type of the proxy server. Katalon Studio currently supports three types of proxy server: HTTP, HTTPS and SOCKS

With this setting, you can manage your external libraries by adding new ones or remove existing ones. Please access the settings at menu Project > Settings > External Libraries.
