voidPayment

mutation · in the family Payment

What it does

Void a payment on an order — cancel it as if it should not have happened, keeping the paper trail.

Void an authorized Payment: the merchant voids the authorization — same release + reversal-tender shape as cancel (the flip + the NEGATIVE Tender row + the Order rollup stamp in ONE transaction), distinct terminal for the audit story. A captured payment has no void edge (FSM_TRANSITION_INVALID — settled money moves through Refunds). Requires the unrestricted capability + the CURRENT revision (OCC).

Careful

Voiding is permanent and always auditable.

Who may call it

Capability area: Gated floor actions — Voids, returns and the requests that need an approval.

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.
reasonStringnoNo further notes.

Returns

Payment Payment! — A Payment — a PROCESSOR-backed payment (the integrated processing mode), spawned by a card Tender. Aligned to the deposit→recognition model: authorize = the hold = DEPOSIT at tender; capture = RECOGNIZED at delivery — POS carry-out collapses authorize+capture by ARRIVING at delivery in the same request (the settle instant delivers), never by skipping states. Record-first/processor-after: minted created BEFORE any processor call; the StripePort attempt fires post-commit; state flips ride the ACK/webhook path; 32 attempts bound each order (the Order.paymentIds cap). PCI-min: the PAN never touches AT/stack — the record holds the opaque tokenized methodRef + processor refs + at most brand/last4. The StripePort is FAKED at 7.7a (deterministic, keyless); the live adapter + webhook ingress are 7.7b.
