## Arguments
* [input](/docs/api/admin/unstable/input-objects/QuantityPricingByVariantUpdateInput): QuantityPricingByVariantUpdateInput! - The input data used to update the quantity pricing in the price list.
* [priceListId](/docs/api/admin/unstable/scalars/ID): ID! - The ID of the price list for which quantity pricing will be updated.
## Returns
* [productVariants](/docs/api/admin/unstable/objects/ProductVariant): ProductVariant The variants for which quantity pricing was created successfully in the price list.
* [userErrors](/docs/api/admin/unstable/objects/QuantityPricingByVariantUserError): QuantityPricingByVariantUserError! The list of errors that occurred from executing the mutation.
