updateStoredValueInstrument

mutation · in the family Stored value instrument

What it does

Edit a gift card or store-credit instrument — customer-held, money-like — change its details.

Edit a StoredValueInstrument's mutable attributes. Requires the unrestricted capability + the record's CURRENT revision.

Careful

Edits take effect immediately and write a new revision; the old revision stays in history.

Who may call it

Capability area: Till and cash management — Manual drawer entries and force-closing a till.

Arguments

NameTypeRequiredNotes
idID ID!yesThe id of the record.
revisionID ID!yesThe revision id you read on the record; the change is refused if an edit landed in the meantime.
inputEditStoredValueInstrumentInput EditStoredValueInstrumentInput!yesNo further notes.

Returns

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).

Errors this call can answer

Dry run

Add dryRun: true to the request envelope (extensions.at) to rehearse this call: every check runs, the write is rehearsed against the current records and nothing is stored; the answer is the refusal a real call would give, or the record it would create. Every response to a rehearsal carries dryRun: true, so a rehearsed record is never mistaken for a saved one.
