# API Authentication

In this tutorial we'll cover the API Authentication Helper for authenticating against API endpoints.

To use the **API Authenticator Helper**, you must first have an **API test** set up, or be in the process of setting up an API test.

So for our example we are using the **example API tests**which **Quality Modeller**automatically creates upon the creation of a **new API Automation project.**

Open an existing **API test module collection**or create a new one following the documentation article above.

Then hit the **blue edit module** button to open the **Edit Function** window.

In the **Edit Function window** navigate to the **API Request tab,** here you will find the **API Authenticator**button! The **API Authenticator** is the grey**Padlock button** next to the**Run button.**

Clicking the **Padlock** will open the **Request Authorization window,** here you can overlay **basic**, or**token** based authentication into an**API request.**

Once you set up your **Authentication Overlay,** it will appear as **“Authorization”**in the **Header Tab**under **API Request** and run alongside your API calls.
