title: inventorySetQuantities - GraphQL Admin
description: >-
  Set quantities of specified name using absolute values. This mutation supports
  compare-and-set functionality to handle

  concurrent requests properly. If `ignoreCompareQuantity` is not set to true,

  the mutation will only update the quantity if the persisted quantity matches
  the `compareQuantity` value.

  If the `compareQuantity` value does not match the persisted value, the
  mutation will return an error. In order to opt out

  of the `compareQuantity` check, the `ignoreCompareQuantity` argument can be
  set to true.


  > Note:

  > Only use this mutation if calling on behalf of a system that acts as the
  source of truth for inventory quantities,

  > otherwise please consider using the
  [inventoryAdjustQuantities](https://shopify.dev/api/admin-graphql/latest/mutations/inventoryAdjustQuantities)
  mutation.

  >

  >

  > Opting out of the `compareQuantity` check can lead to inaccurate inventory
  quantities if multiple requests are made concurrently.

  > It is recommended to always include the `compareQuantity` value to ensure
  the accuracy of the inventory quantities and to opt out

  > of the check using `ignoreCompareQuantity` only when necessary.


  > Caution:

  > As of 2026-01, this mutation supports an optional idempotency key using the
  `@idempotent` directive.

  > As of 2026-04, the idempotency key is required and must be provided using
