# Introduction

> The Business API is a REST API with resource-oriented URLs, JSON request and response bodies, and standard HTTP status codes and methods.

## Overview

The Noah Business API is organised around REST, using resource-oriented URLs.

It accepts JSON-encoded request bodies and returns JSON-encoded responses.

All of Noah's endpoints follow REST conventions and use standard HTTP response codes, authentication, and methods.

### Sandbox and Production Environments

The Noah Business API operates in two distinct environments:

- `sandbox` for testing
- `prod` for live use

For information on setting up your account, visit [Quick Start](../getting-started/quick-start.md).

#### Sandbox Environment

The Sandbox is a safe, simulated environment for testing your integrations.

It allows you to test API requests and transactions in a simulated environment without affecting real-world data, using testnet blockchain networks.

:::tip

Be aware that CryptoCurrencies used in the Sandbox always have a `_TEST` suffix, such as BTC_TEST and USDC_TEST. For details on Noah's USDC_TEST token, see [Sandbox Testnet Currencies](../api-concepts/testnet-currencies.md).

:::

**Note:** The API keys that you generate in the Sandbox are exclusive to this environment. For details, see [Business Dashboard](../getting-started/business-dashboard.md).

#### Production Environment

After you complete testing in the Sandbox, you move your applications to the Production Environment for real-world operations.

Here, your applications interact with live data, real cryptocurrencies, fiat currencies, and connects with blockchain networks.

API keys for Production are distinct and tailored for secure live operations.
