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
Follow the steps below to enable this validation in your store.
Open Settings
Navigate to your Shopify Admin dashboard and click on Settings from the bottom-left corner of the sidebar.
Navigate to Checkout Settings
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.

Add a New Rule
In the Checkout rules section, click the Add rule button. A modal will appear listing the available checkout rule extensions.

Select the SureBright Cart Validator
In the modal, locate the SUREBRIGHT - EXTENDED WARRANTY section and click on sb-cart-validator to select it.

Configure and Save the Rule
Ensure the Allow all customers to complete checkout option is checked under the “If the app fails or experiences a problem” section. This ensures that orders are still processed even if the validation app encounters an issue. Click Save to apply your changes.

Turn On the Rule
After saving, click the Turn on button in the top-right corner to activate the checkout rule. Once enabled, the sb-cart-validator will appear with an Active status badge under the Checkout rules section.

Verify the Setup
The SureBright Cart Validator is now active on your store. 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 since the “Allow all customers to complete checkout” fallback option is enabled. This ensures a seamless customer experience at all times.
