# Authentication

The Yuko API uses HTTP Bearer Authentication to authenticate requests. All API requests must be made over HTTPS.

To authenticate, include your API key in the `Authorization` header of every request:

```
Authorization: Bearer YOUR_API_KEY
```

You can find your API key in the [Yuko Dashboard](https://app.yukoapp.com) under **Settings → API**.

Keep your API keys secure. Do not expose them in client-side code, mobile app binaries, or public repositories. All API calls containing your secret key must be made from your backend server.
