KlickTipp PHP Connector

The KlickTipp PHP Connector is a lightweight PHP interface class for working with the KlickTipp REST API.
It supports three authentication methods:

• Session login (username + password)
• API key (listbuilding)
• Developer key + customer key (partner integrations)

This library is ideal for simple integrations, legacy systems, or server environments without additional HTTP client libraries.
