If you're curious about how BoxBuilder integrates with Shopify or operates on the backend, you'll be pleased to know that the app makes effective use of Shopify's product template. As we finish creating a builder, it automatically generates a shadow product within the Shopify product section.
After your customer finishes the builder journey, the system automatically creates a variant with a random SKU. This variant will be used as the placement for the completed product builder or bundle the products into a single product with a single price.
NOTE: This variant should not be deleted because this may create an error from the storefront when completing the builder.
