# Introduction

> Understand general concepts, response codes, and authentication strategies.

## Base URL

The Steuerboard API is built on REST principles. We enforce HTTPS in every request to improve data security, integrity, and privacy. The API does not support HTTP.
All requests contain the following base URL:

```
https://api.steuerboard.com/v1
```

## Authentication

To authenticate you need to add an Authorization header with the contents of the header being Bearer sb\_xxxxxxxxx where sb\_xxxxxxxxx is your API Key.

```
Authorization: Bearer sb_xxxxxxxxx
```
