Introduction

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.

The Noah Business API operates in two distinct environments:

For information on setting up your account, visit Quick Start.

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

Sandbox requests use the sandbox code in the table below. Testnet contract addresses are on Sandbox Testnet Currencies.

Note: The API keys that you generate in the Sandbox are exclusive to this environment. For details, see Business Dashboard.

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.
