  mutation

  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.

For more information, see the [idempotency documentation](https://shopify.dev/docs/api/admin/idempotency).
