Frequently Asked Questions
What formats are supported?
Both JSON and YAML formats are supported for OpenAPI 3.x (openapi: "3.x.x") and Swagger 2.0 (swagger: "2.0") specifications.
How is authentication handled?
Security schemes (API Key, HTTP Basic/Bearer, OAuth2) defined in the spec are converted to Postman auth configurations. You will need to replace placeholder values with actual credentials.
Are request bodies generated?
Yes, for OpenAPI 3.x specs with requestBody definitions, example JSON bodies are generated based on the schema properties and types.
Can I import this directly into Postman?
Yes! Download the JSON file and import it into Postman via File → Import → Upload Files. The collection will be ready to use immediately.
Is my data sent to a server?
No, all conversion happens entirely in your browser. Your API specification never leaves your device.
