Supports: - Product IDs (gid://shopify/Product/...): Returns product with match: "featured" - Variant IDs (gid://shopify/ProductVariant/...): Returns parent product with the exact variant Results are grouped by product. Each variant includes an inputs array showing which request ID resolved to it and whether the match was exact or featured. In versions that require input correlations, only matched variants are returned.

}Perform updates to a cart. Prices in the response are integers in the currency's ISO 4217 minor units, paired with a currency code: {"amount": 600, "currency": "USD"} is $6.00 and {"amount": 2500, "currency": "USD"} is $25.00. Convert to major units before quoting a price to a buyer (divide by 100 for two-decimal currencies such as USD and EUR; zero-decimal currencies such as JPY are already whole units).
