# Authentication

> API key authentication for the Ramping API

<Warning>
  **Preview Documentation** — This integration is in final testing. API shapes are stable; endpoints will be live shortly. Contact your RebelFi rep if you have questions before go-live.
</Warning>

All Ramping API requests require an API key passed in the `x-api-key` header:

```bash theme={null}
curl -X GET "https://api.rebelfi.io/v1/ramp/recipients" \
  -H "x-api-key: your_api_key_here"
```

## API Key Management

* **One API key per account.** View or regenerate your key from the dashboard **Settings** page.
* Keys should be stored as environment variables and never committed to version control.

```bash theme={null}
export REBELFI_RAMP_API_KEY="your_api_key_here"
```

<Warning>
  Treat your API key like a password. If you suspect a key has been compromised, regenerate it immediately from the dashboard.
</Warning>
