## Prevent Unauthorized Warranty Purchases with Built-in Fraud Protection
The SureBright Cart Validator acts as a fraud prevention layer within your Shopify store, designed to block the purchase of warranty products through unauthorized or unintended channels.
Warranty plans are meant to be purchased alongside their corresponding products. However, in certain cases, customers may attempt to add and purchase warranty policies independently — leading to invalid coverage, operational challenges, and potential misuse.
To address this, SureBright establishes intelligent checkout validation rules that enforce correct purchase behavior.
Once enabled, the Cart Validator ensures that:
- Warranty products cannot be purchased as standalone items
- Each warranty policy is always tied to an eligible product in the cart
- Invalid or suspicious checkout attempts are automatically blocked
By enforcing these rules at checkout, you not only maintain data integrity but also protect your store from misuse, ensuring that every warranty sold is valid and compliant.
## Follow the steps below to enable this validation in your store.
Navigate to your Shopify Admin dashboard and click on **Settings** from the bottom-left corner of the sidebar.
In the Settings menu, click on **Checkout** from the left-hand navigation panel. Scroll down to the bottom of the page to locate the **Checkout rules** section.
In the **Checkout rules** section, click the **Add rule** button. A list of available checkout rule extensions will appear. Locate the **SUREBRIGHT - EXTENDED WARRANTY** section and click on **sb-cart-validator** to select it.
The **Checkout rule for sb-cart-validator** page will open with an **Inactive** status. Enter a **Title** for the rule. Leave the **Block checkout if app experiences a problem** option unchecked, so that orders are still processed even if the validation app encounters an issue.
Click the status dropdown next to the Title field and change it from **Inactive** to **Active**.
Click **Save changes** to apply the rule. Once saved, the page header will display the rule title with an **Active** status badge.
Navigate back to the **Checkout rules** section in your Checkout settings. The rule will now appear with an **Active** status badge. To confirm everything is working correctly, perform a test by completing a basic user journey through to the checkout page. Attempt to add a SureBright warranty product without its associated product to verify that the validation is triggered as expected.
If the cart validator app encounters an error, the checkout will still proceed normally as long as the **"Block checkout if app experiences a problem"** option is left unchecked. This ensures a seamless customer experience at all times.
