API/Web Service Project
Katalon Studio currently 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 request history at any time.
The update comes with a new interface, including a new toolbar and view that serve only for API/Web Service testing. To create the New API/Web Service Project, in New Project dialog, simply select API/Web Service type and specify all required project information.
The main toolbar contains API/Web Service testing related features only to help you navigate around the app easily and intuitively.
Request History Panel
Same with a normal Katalon Project, the left column now have Request History view where all the sent requests are saved here. You can freely access and retrieve them to work or save as a request object in the Object Repository.
