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 > import the service definition in two ways:

    • With an API or Web Service project type, click on the OpenAPI icon > select Import OpenAPI 3.

    • Or in the Tests Explorer, right-click on Object Repository > select Import > From OpenAPI 3.

  2. In the displayed dialog, browse your OpenAPI 3.0 local file > click OK.

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