title: inventoryAdjustQuantities - GraphQL Admin
description: >-
  Adjusts quantities for inventory items by applying incremental changes at
  specific locations. Each adjustment modifies the quantity by a delta value
  rather than setting an absolute amount.


  The mutation tracks adjustments with a reason code and optional reference URI
  for audit trails. Returns an
  [`InventoryAdjustmentGroup`](https://shopify.dev/docs/api/admin-graphql/latest/objects/InventoryAdjustmentGroup)
  that records all changes made in the operation.

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

  > As of version `2026-04`, the idempotency key is required and must be
  provided using the `@idempotent` directive.
