# Fraud and Risk Prevention API Reference

Explore the details of the Stytch Fraud and Risk Prevention API. Our Fraud and Risk Prevention API is organized around REST principles: it has resource-oriented URLs, returns JSON-encoded responses, and uses standard HTTP response codes, authentication, and verbs.

All Fraud API resources are scoped to the Project of the API keys you provide.

### API keys

The Stytch API uses [basic authentication](https://developer.mozilla.org/en-US/docs/Web/HTTP/Authentication) with your `project_id` and `secret` from the **API Keys** section in the [Dashboard](https://stytch.com/dashboard). You'll need to pass these values into the Authorization request header for every Stytch API call.

### Environments

For every Stytch project, there are multiple **TEST** environments and a single **LIVE** environment. For Device Fingerprinting calls, you must provide the `project_id` and `secret` of the project and environment of your preference.
