Import REST API with OpenAPI Specification 3.0

This manual shows you how to import RESTful APIs with OpenAPI Specification version 3.0 to Katalon Studio. For OpenAPI 2.0 (Swagger), please see the following document.


  • Katalon Studio version 7.7+
  • An active Katalon Studio Enterprise license

To import a service definition with OpenAPI 3.0, please do as follows:

  1. Open or create a project then import the service definition in two ways:
  • With a API/Web Service project type, click on the OpenAPI icon and select the Import OpenAPI 3 option; or

  • In Tests Explorer, right-click on any folder of Object Repository and select Import > From OpenAPI 3.

  1. In the displayed dialog, browse your OpenAPI 3.0 local file or enter an OpenAPI 3 URL, and click OK.

    Katalon Studio loads the file and generates RESTful test requests accordingly.
