## Mutations

* [quantity​Pricing​By​Variant​Update](https://shopify.dev/docs/api/admin-graphql/latest/mutations/quantityPricingByVariantUpdate)

  mutation

  Updates quantity pricing on a [`PriceList`](https://shopify.dev/docs/api/admin-graphql/latest/objects/PriceList) for specific [`ProductVariant`](https://shopify.dev/docs/api/admin-graphql/latest/objects/ProductVariant) objects. You can set fixed prices (see [`PriceListPrice`](https://shopify.dev/docs/api/admin-graphql/latest/objects/PriceListPrice)), quantity rules, and quantity price breaks in a single operation.

  [`QuantityRule`](https://shopify.dev/docs/api/admin-graphql/latest/objects/QuantityRule) objects define minimum, maximum, and increment constraints for ordering. [`QuantityPriceBreak`](https://shopify.dev/docs/api/admin-graphql/latest/objects/QuantityPriceBreak) objects offer tiered pricing based on purchase volume.

  The mutation executes delete operations before create operations and doesn't allow partial updates.

  ***

  Note

  If any requested change fails, then the mutation doesn't apply any of the changes.
