# Authentication

> How to authenticate your requests to the Guppy API

All requests to the Guppy API are authenticated via an API key.

```bash theme={null}
Authorization: Bearer GUPPY_SECRET_KEY
```

Keys are scoped per partner or platform. To obtain an API key, please contact us at [founders@guppy.ai](mailto:founders@guppy.ai).

### Security Best Practices

* Never share your API keys in publicly accessible areas such as GitHub, client-side code, and so forth.
* Use environment variables to store your keys.
* If a key is compromised, contact us immediately to rotate it.
