# Auto-Create Assertions for QuickStart API Automation

Creating assertions for API tests has become extremely easy with Quality Modeller. By simply clicking a button, Quality Modeller can execute a sample request and generate assertions on-the-fly based on the characteristics of the API response. These assertions can then be used in test automation to ensure the proper functioning of the API.

To utilise the new **API Assertions,** open an existing **API Module collection** and edit the **API Function** you want to add the assertions to. ![](https://cdn.document360.io/77f722a6-2d0a-49fa-8074-572515a6c4b8/Images/Documentation/Screenshot%202023-09-18%20150432.png)

In the **Edit Function window**, open the **API Requests tab** and then the **Assertions SubTab.** In the **Assertions SubTab**, you can now use the **AutoBuild button** to automatically create a range of assertions for your API Request.

Once done, you will see a range of automatically generated API Assertions:
