Partial product updates

Last updated Oct 8, 2026 View as Markdown

• An omitted field keeps its current value. See Update a product.
• A list you send (images, variants, variant_options, categories, vendors) replaces the current list. An omitted list is not changed.
• variant_options must come with variants, and variants must come with has_variants.
• compare_at_price is checked against the current price when you send only one of them.

Fixed

• An update that omitted advanced_options reset the product's advanced options. They are now kept.
