[Embedded content](https://www.youtube.com/embed/BHi5oENOHoU?&wmode=opaque&rel=0) 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.** ![](https://cdn.document360.io/77f722a6-2d0a-49fa-8074-572515a6c4b8/Images/Documentation/image-1681814594011.png) Open an existing **API test module collection** or create a new one following the documentation article above. ![](https://cdn.document360.io/77f722a6-2d0a-49fa-8074-572515a6c4b8/Images/Documentation/image-1681814615241.png) Then hit the **blue edit module** button to open the **Edit Function** window. ![](https://cdn.document360.io/77f722a6-2d0a-49fa-8074-572515a6c4b8/Images/Documentation/image-1681814620131.png) 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.** ![](https://cdn.document360.io/77f722a6-2d0a-49fa-8074-572515a6c4b8/Images/Documentation/image-1681814630695.png) Clicking the **Padlock** will open the **Request Authorization window,** here you can overlay **basic**, or **token** based authentication into an **API request.** ![](https://cdn.document360.io/77f722a6-2d0a-49fa-8074-572515a6c4b8/Images/Documentation/image-1681814642801.png) 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. ![](https://cdn.document360.io/77f722a6-2d0a-49fa-8074-572515a6c4b8/Images/Documentation/image-1681814648704.png)
