## Environment Switching

Our documentation includes built-in environment switching functionality:

1. **Staging Environment** (`api.staging.kairosafrika.com`): Perfect for development and testing
2. **Production Environment** (`api.kairosafrika.com`): For live applications

When viewing API endpoints, you'll see a dropdown at the top of each API playground that allows you to switch between environments. Your selection persists across all API sections for a consistent testing experience.
