## Authentication Overview

The KlickTipp Management API supports **multiple authentication models**, depending on the integration scenario.

- **Username and password authentication via session cookie**
Typically used for internal tools and administrative workflows.
- **Developer key and customer key authentication**
Intended for long-running, production-grade, or multi-tenant integrations.
This model does not rely on session handling.
