# Introduction

The Flip.to API is organized around REST. It is a standards-based API that has predictable resource-oriented URLs, accepts form-encoded request bodies, returns JSON-encoded responses, and uses standard HTTP response codes, authentication, and verbs.

## API Authorization

All requests must be authorized with an API Key that is available in your Flip.to account. It should be sent using basic authentication as the “username” with no password. For example, if the key were “nevergoingtogiveyouup:”, the requests would need a header like this in base64:

```
Authorization: Basic bmV2ZXJnb2luZ3RvZ2l2ZXlvdXVwOg==
```
