Product structure, handles, SKUs, and variants
Identifiers and variant structure are the foundation of a catalog. Duplicate or malformed values make exports, integrations, reporting, and later cleanup harder to reason about.
- Every product has a title and handle.
- Product handles are unique and use a predictable URL-safe format.
- SKUs that should identify variants are present and not duplicated across unrelated variants.
- Variant option data is structurally valid.
- A product does not contain the same variant option combination more than once.
