# Environment Domains

> API endpoints for Sandbox and Production environments

CommerceCash provides separate environments for **Sandbox** and **Production** to support development, testing, and live transactions.

## API Domains

CommerceCash organizes APIs into dedicated services. Each service has its own base URL while sharing the same authentication and security model.

# Switching to Production

***

# Best Practices

<Info>
  Only the **Base URL** changes between Sandbox and Production. All API endpoints, request payloads, response formats, and authentication methods remain identical.
</Info>

<Info>
  Store API domains and credentials in configuration files or environment variables instead of hardcoding them into your application.
</Info>

<Warning>
  Do not use Sandbox credentials against Production endpoints, or Production credentials against Sandbox endpoints.
</Warning>
