# Authentication

To perform API calls and access Truora's services, authentication is a fundamental requirement. This is achieved by including a specific authentication token in the **header** of your requests, known as the **"Truora-API-Key"**.

This unique key serves as your digital credential, granting you access to the Truora API's functionality securely. By providing this key in the **header** of your API requests, you establish a secure and authorized connection, enabling you to interact with Truora's services seamlessly and confidently.
