Returns true if an owned product was deleted, false if none matched. Throws a 409 CONFLICT error (with an extension code of PRODUCT\_SOURCE\_MANAGED, PRODUCT\_HAS\_LISTING, or PRODUCT\_HAS\_INVENTORY) if the product is ineligible for deletion. * [`deleteProductFamily`](/docs/api-reference/v3/reference/catalog/mutations/delete-product-family) — Delete a product family and all of its products. Returns true if an owned product family was deleted, false if none matched. Throws a 409 CONFLICT error (with an extension code of PRODUCT\_SOURCE\_MANAGED, PRODUCT\_HAS\_LISTING, or PRODUCT\_HAS\_INVENTORY) if the family or any product is ineligible for deletion. * [`syncSalesChannelVariants`](/docs/api-reference/v3/reference/catalog/mutations/sync-sales-channel-variants) — Resolve sales channel variant ids to products here, syncing any that do not exist yet. Returns one entry per requested variant id, in the order given; a variant the sales channel does not have resolves to NOT\_FOUND rather than failing the request. Variants already present are returned without calling the sales channel. Throws a 400 error when a variant id is not in the sales channel's id format (for Shopify, gid://shopify/ProductVariant/\), and a 400 error (with an extension code of SALES\_CHANNEL\_NOT\_CONNECTED) when the sales channel is not connected. ## Objects * [`Attribute`](/docs/api-reference/v3/reference/catalog/attribute) — A typed attribute defined by the merchant and attached to a product or product family. * [`Dimensions`](/docs/api-reference/v3/reference/catalog/dimensions) — A product's length, width, and height expressed in a single shared unit. * [`Product`](/docs/api-reference/v3/reference/catalog/product) — A specific sellable product (a variant under a product family). * [`ProductFamily`](/docs/api-reference/v3/reference/catalog/product-family) — A merchant catalog item — a group of related products (variants). * [`ProductFamilyImage`](/docs/api-reference/v3/reference/catalog/product-family-image) — An image attached to a product family. * [`ProductFamilyOption`](/docs/api-reference/v3/reference/catalog/product-family-option) — A variant option (e.g. Size, Color) for a product family, with its allowed values. * [`ProductImage`](/docs/api-reference/v3/reference/catalog/product-image) — An image attached to a specific product (variant). * [`ProductOptionValue`](/docs/api-reference/v3/reference/catalog/product-option-value) — A variant's selected value for one of its family's options (e.g. Size: M). * [`SyncedVariant`](/docs/api-reference/v3/reference/catalog/synced-variant) — The result of resolving one sales channel variant to a product here. * [`Weight`](/docs/api-reference/v3/reference/catalog/weight) — A weight as a `{ value, unit }` pair, e.g. `{ value: 1.5, unit: KILOGRAM }`. ## Input objects * [`CreateProductFamilyInput`](/docs/api-reference/v3/reference/catalog/create-product-family-input) — The input for creating a new product family. * [`CreateProductInput`](/docs/api-reference/v3/reference/catalog/create-product-input) — A product (variant) to create under the new family. * [`DimensionInput`](/docs/api-reference/v3/reference/catalog/dimension-input) — A length as a `{ value, unit }` pair. * [`ProductFamilyOptionInput`](/docs/api-reference/v3/reference/catalog/product-family-option-input) — An option (e.g. Size) to create on the new family. * [`ProductOptionValueInput`](/docs/api-reference/v3/reference/catalog/product-option-value-input) — A variant's selected value for one of the family's options (e.g. Size: M). * [`SyncSalesChannelVariantsInput`](/docs/api-reference/v3/reference/catalog/sync-sales-channel-variants-input) — The sales channel variants to resolve to products, syncing any that are missing. * [`WeightInput`](/docs/api-reference/v3/reference/catalog/weight-input) — A weight as a `{ value, unit }` pair. ## Enums * [`AttributeType`](/docs/api-reference/v3/reference/catalog/attribute-type) — The data type of a merchant-defined attribute. Determines the JSON shape of the attribute's `value` (documented on each enum value). * [`DimensionUnit`](/docs/api-reference/v3/reference/catalog/dimension-unit) — A unit of length used to express a product's dimensions. * [`ProductFamilySortKey`](/docs/api-reference/v3/reference/catalog/product-family-sort-key) — A field this list can be ordered by; pass to the list's `orderBy` argument and pair with `reverse` to flip direction. * [`ProductSortKey`](/docs/api-reference/v3/reference/catalog/product-sort-key) — A field this list can be ordered by; pass to the list's `orderBy` argument and pair with `reverse` to flip direction. * [`SalesChannel`](/docs/api-reference/v3/reference/catalog/sales-channel) — An external sales channel a product can be synced from on demand. * [`VariantSyncOutcome`](/docs/api-reference/v3/reference/catalog/variant-sync-outcome) — What happened to one requested sales channel variant. * [`WeightUnit`](/docs/api-reference/v3/reference/catalog/weight-unit) — A unit of mass used to express a product's weight.
