# Introduction

**eSIM Story API** provides REST endpoints for eSIM orders.

## Quick Start

To get started with the API, you'll need to:

1. **Get your API credentials** - Contact support to receive your API keys
2. **Authenticate** - Use your credentials to authenticate requests
3. **Make your first request** - Start creating eSIM orders

## Base URL

The API is available in two environments:

### Sandbox

```
https://sandbox-api.esimstory.com/api
```

### Production

```
https://api.esimstory.com/api
```

<Warning>
  Sandbox and production environments require separate API keys. Use sandbox
  keys for testing and development. Sandbox orders use test data and do not
  result in actual eSIM purchases. Use production keys only for live orders.
</Warning>

## Authentication

Most endpoints require authentication. See the [Authentication guide](/authentication/overview) for details.
