App settings
This section allows you to control how the app works on your store.
- Checkout Validation
Checkout Validation helps block orders at the checkout page when the order violates your limit rules. This feature is especially for stores that are NOT using Shopify Plus.
Simply turn the toggle ON in App Settings. When the status shows “Checkout rules status: On”, the feature is active.
Important notes: When this feature is enabled, the app will automatically work across Shopify channels, including: Online Store, Shopify POS, Shop App.
- Mix & Match limit rules
When a variant is added to the cart, it must meet the following rules in order
- Variant rule (If any)
- Product rule (If any)
- Collection rule (If any)
- All Product rule (If any)
- Example, you have 2 limit rules
⇒ Customer must purchase 1 to 3 units of Product A and at least one additional product to ensure the total cart quantity exceeds 5 before thay can proceed to checkout
- Rule 1: Product A quantity must be between 1 and 3
- Rule 2: Total cart quantity must be greater than 5
- Enable Multiple on the Cart Page
When this option is enabled:
- On the cart page, if customers change the quantity,
- The quantity will automatically adjust to match the correct multiple you have set.
- Sync product data
Click Sync Data to allow the app to fetch the latest product information from your store. We recommend syncing when: add new products, update product variants, limit rules are not applying correctly,... The ensures your rules work with the most up-to-date product data.
- Debug Mode - Share Function Logs
If Checkout Validation is not working correctly, or customers are still able to purchase restricted products. Please click Share logs in the Debug mode section. This will send function logs to our support team so we can check what went wrong and fix the problem faster.
