Authentication concept: API keys and sandbox accounts

How authentication works in the Leafy Energy API (demo)

In the demo we use a simple API key model to illustrate integrations. A real production setup might add OAuth or other flows.

API key in the demo

• Each demo customer receives a fictional API key (for example via the portal).
• The key is sent in the Authorization header.

GET /v1/customers/me
Authorization: Bearer DEMO_API_KEY_123

Sandbox accounts

• Sandbox keys might start with sb_.
• In training you can show how code switches environments based on key prefixes.

This article serves as a conceptual overview before you dive into detailed security and scopes.
