# Extracted Value Assertion for API Tests

In this Quality Modeller feature video, you will learn how to form an assertion on extracted JSON values for API tests.

Additionally, [**check out our QuickStart API Automation guide!**](/docs/quickstart-api-automation)

**[Embedded content](https://www.youtube.com/embed/Vwqg1QSvWaE?&wmode=opaque&rel=0)**

To get started with this demo, we have a module with an**API Request** set-up. Open up your own module with an**API Request,**to do this, navigate to the**Explorer in Quality Modeller**, Open a Module and then hit the **Blue Action button.**

This will open the**Edit Function**menu for your module, from here open the **API Request tab** and then navigate to**Assertions.**

In the **Assertions tab**, you can add new Assertions by hitting the**Add button.**Here, you will be able to add two new types of Assertions, as shown in the demo you can add **JSON Path and Custom Code assertions.**

This will propagate in the module, and you can view the results by hitting the**Generate button.** This will show you the generated code, including the JSON path and Custom code assertions we just set up.
