This API allows you to update the tier structure of a product. Defining only color creates one tier, while color + size creates two tiers (maximum supported). Supported changes include: no tier ↔ one/two tiers, one tier ↔ two/no tier, and two tiers ↔ one/no tier. For details, see Developer Guide. Please wait at least 5 seconds after creating an item before creating variants, as processing may be delayed.
