# adjustStoredValueInstrument

mutation · in the family [Refunds and payment corrections](/reference/refunds-and-payment-corrections/)

## What it does

Manually correct a gift card or store-credit balance, with a reason.

ADJUST an instrument balance — the privileged manual correction: a SIGNED non-zero delta + the REQUIRED reason post ONE adjust entry + the CONDITIONED cached-balance apply (below-zero refuses CONFLICT/INSUFFICIENT_BALANCE naming the live figures). active|depleted targets only (CONFLICT/REF_STATE otherwise); a positive adjust on depleted RE-OPENS it (system:refund_credit); a draw landing ZERO on a non-reloadable flips depleted in the SAME transaction. Requires the unrestricted capability + the record's CURRENT revision.

## What happens

Posts a signed balance entry on the instrument’s ledger.

## Careful

This is money movement on a customer-held instrument — every entry is permanent and auditable.

## Arguments

| Name | Type | Required | Notes |
| --- | --- | --- | --- |
| `instrumentId` | [ID](/types/#scalars) `ID!` | yes | No further notes. |
| `revision` | [ID](/types/#scalars) `ID!` | yes | The revision id you read on the record; the change is refused if an edit landed in the meantime. |
| `amountMinor` | [Int](/types/#scalars) `Int!` | yes | No further notes. |
| `reason` | [String](/types/#scalars) `String!` | yes | No further notes. |

## Returns

[StoredValueInstrument](/types/StoredValueInstrument/) `StoredValueInstrument!` — A StoredValueInstrument — a balance-bearing money instrument: gift_card (purchasable, reloadable-by-field, bearer) · gift_certificate (fixed-amount) · store_credit (refund/goodwill-born, customer-BOUND, never purchasable as a line). The FSM tracks USABILITY; the StoredValueEntry ledger tracks VALUE — balanceMinor is the cached ledger sum, stamped in the SAME transaction as every entry (the / law), with every decrement CONDITIONED (never negative — CONFLICT/INSUFFICIENT_BALANCE). Dual-birth: immediate active (the issue entry rides the create) or STAGED inactive printed stock (activated at sale via the Order line arm, or directly via activateStoredValueInstrument). Selling/reloading one is an Order LINE (untaxed — basis instrument_sale; engine-invisible); redeeming one is an applyTender step-5 internal tender; store credit from a return mints via refundReturn method=store_credit. Doom is gated by CONFLICT/BALANCE_OUTSTANDING while value remains (zero via reason-coded adjust FIRST — no silent money destruction).
