Mint a rotating QR / short-code for the customer's wallet app

Generates a rotating, single-use QR nonce (and optional 5-character short code) for the customer to display at the point of sale. The nonce is bound to the customer’s wallet identity and has a 5-minute TTL. The point of sale then submits the nonce to POST /payments as credential.type: qr, or submits the alphanumeric variant as credential.type: short_code.

The underlying QR session uses compare-and-swap status transitions: presenting a QR at the point of sale while a new mint is requested concurrently will not cancel the in-flight payment, and the presented nonce remains valid. Re-minting before the TTL expires returns a new nonce and invalidates the previous one.

Requests are idempotent on the Idempotency-Key header: a retried mint with the same key returns the same nonce while it remains within its TTL. The endpoint is terminal-scoped and can be driven by either the point-of-sale app or the customer’s wallet app. A request scoped to a different tenant returns 403 or 404.

Authorizations

Authorization

string

header

required

POS terminal JWT minted by /auth/token; carries integrationId + terminal/cashier claims (server-trusted).

Headers

Idempotency-Key

string<uuid>

required

Partner-generated UUID; the ONE dedup key for all mutating endpoints. 24h TTL. Same key + same payload -> byte-identical replay; same key + different payload -> IDEMPOTENCY_KEY_REUSED (422).

Body

application/json

Response

QR nonce minted. Render qr_payload as a QR code and optionally display short_code for manual entry.

The standard response envelope that every enveloped endpoint serializes through. ok is a boolean discriminator: when ok is true, the typed result is carried in data; when ok is false, a typed error object is returned instead. The meta object is uniform across the entire API surface.
