# Introduction

## Authentication

All API endpoints are authenticated using Bearer tokens and picked up from the specification file.

```json theme={null}
"security": [
  {
    "bearerAuth": []
  }
]
```

To get a Bearer token, you must request one from Zayo here: [Zayo Developer Portal](https://developer.zayo.com/)
