# Introduction

> Learn how to integrate with Kan's REST API.

## Base URL

```
https://kan.bn/api/v1
```

## Authentication

Most endpoints require authentication using your API key. You can create one in the [settings page](https://kan.bn/settings) of your account. Include this key as a Bearer token in the `Authorization` header of each request.

```
'Authorization': 'Bearer kan_123456789'
```

## Response codes

Kan uses standard HTTP codes to indicate the success or failure of your requests.

In general, `2xx` HTTP codes correspond to success, `4xx` codes are for user-related failures, and `5xx` codes are for infrastructure issues.

| ------ | ------------------------------- |
| `200`  | Success                         |
| `400`  | Invalid parameters              |
| `401`  | Missing token                   |
