API/Web Service project in Katalon Studio

Katalon Studio supports API/Web Service testing project, which allows separating the API/Web Service testing from Web UI and Mobile testing. You can also perform more API/Web Service automation tasks on Katalon Studio such as Quickstart wizard, import Swagger or WSDL definition File/URL directly, or retrieve the request history at any time.

The update comes with a interface, including a toolbar and a view that serve only for API/Web Service testing.

In Katalon Studio - Standalone Edition, to create a new API/Web Service project, select API/Web Service type in the New Project dialog and specify all required project information.

Create a new Web Service

In Katalon Studio - Platform Edition, go to Project Information > Project Type > WebService to change project type and enable the toolbar for API testing.
