## Import into API tools

Most API clients can import an OpenAPI document directly from a URL. Copy one of the links above, then choose **Import** in Postman or Insomnia and paste it.

A collection generated this way contains every endpoint and schema, but no environment, credentials, or example values. To make live requests against a simulated vehicle instead, start with [Using the Vehicle Simulator with Postman](/docs/getting-started/using-vs-with-postman). It uses a prebuilt collection and environment, so you can send your first request without wiring anything up.
