Visually Preview and Download Data & Multimedia API Responses - Inspect the API Response (HTTP status code, error message, headers, body, time taken). - View formatted code previews for responses of various content types like JSON, XML, YAML, HTML, SQL, etc. - API Dash helps explore, test & preview Multimedia API responses which is not supported by any other API client. You can directly test APIs that return images, PDF, audio & more. - Save response body of any mimetype (image, text, etc.) directly in the Downloads folder of your system by clicking on the Download button. Code Generation - We started out as the only open source API client which supported advanced Dart code generation to easily integrate APIs in Dart/Flutter projects or to directly run it on DartPad. With time we have added more code-gens and currently API Dash supports generation of well-tested integration codes for JavaScript, Python, Kotlin & various other languages. Full Dark Mode Support - Easily switch between light mode and dark mode. Data - Data is persisted locally on the disk. To save the current snapshot, just press the Save button in the collection pane. - Click and open the collection/folder popup menu to export it as HAR. This can be version controlled & can be directly imported in other API Clients like Postman, Paw, etc. - Export your entire data into a HAR (HTTP Archive) file. To access this option goto Settings > Export Data.
