This page introduces how to set up a product quantity rule to ensure that for a product with variations (e.g., S, M, and L sizes), a maximum of 3 items can be purchased for each variant.
Note: If you have not yet enabled the app embed, please do so from the initial setup guide.
By following the settings on this page, you can apply a quantity limit so that customers can only purchase up to 3 items for each variant of the target product. If a customer attempts to purchase 4 or more items of a specific variant, an alert message will be displayed.
The following example explains a case where a target product has size variants: "S, M, and L."
✅ Purchasable cases (Each size variant is within 3 items)
3 S items → All within 3 items
2 S items + 3 M items → All within 3 items
2 S items + 2 M items + 3 L items → All within 3 items
❌ Non-purchasable cases (A size variant with 4 or more items exists)
4 S items → At least one variant has 4 or more items
3 S items + 4 M items → At least one variant has 4 or more items
2 S items + 2 M items + 4 L items → At least one variant has 4 or more items
