[Embedded content](https://www.youtube.com/embed/vl7iskEvM9c?&wmode=opaque&rel=0) The new validation feature works when editing functions, modules and other objects in Quality Modeller. To edit functions, you need to have pre-existing module collections, or use example ones already present in Quality Modeller. In our example, we’re going to edit an **API Request module.** To edit a module, navigate to its location in the **Explorer view** and then click the name of the module to open the **Edit Function window.** ![](https://cdn.document360.io/77f722a6-2d0a-49fa-8074-572515a6c4b8/Images/Documentation/image-1681816962296.png) For our example, we edit the **Body tab** of an **API Request** in the **Edit Function window**, and then hit **save.** ![](https://cdn.document360.io/77f722a6-2d0a-49fa-8074-572515a6c4b8/Images/Documentation/image-1681816967005.png) Due to our edit, there is now an error in the **Body** of the **API Request**, which means the **Validation pop up** will appear once we hit save. ![](https://cdn.document360.io/77f722a6-2d0a-49fa-8074-572515a6c4b8/Images/Documentation/image-1681816972603.png) The **Validation pop up** will explain the error and give you the opportunity to fix it, or ignore it, reducing the number of errors when setting up your various modules in Quality Modeller. ![](https://cdn.document360.io/77f722a6-2d0a-49fa-8074-572515a6c4b8/Images/Documentation/image-1681816977738.png) ## Related - [Quality Modeller 101](/test-modeller-101.md) - [Building Models in Quality Modeller](/building-models-in-test-modeller.md)
