Execute HTTP requests
Sometimes it is necessary to check API requests manually before automated test writing. With the HTTP Client plugin, you can create, edit, and execute HTTP requests directly in the editor for testing purposes.

Preview and generate code from an OpenAPI specification
You can preview an OpenAPI specification using the integrated Swagger UI.
When an OpenAPI specification file is opened in the editor, use the Open Editor Preview button and the Editor only button in the top-right corner to show or hide the preview. When you have a valid OpenAPI specification open, Aqua suggests generating code from it.
For detailed information about the OpenAPI features, refer to the OpenAPI section.
