  Redeemed by the payment verbs and by POST /v1/orders (orders.create), cancel (orders.cancel) and amend COMMIT (amend.commit). Human sessions and system keys are exempt. Single use, ~2 min TTL, bound to tenant + action + resource + amount; any drift fails closed and burns the token.

    Canonical code or alias per the domain registry; unknown = 400 UNKNOWN_DOMAIN.Show more

    Canonical code or alias per the domain registry; unknown = 400 UNKNOWN_DOMAIN. APTSVC (airport services: meet and assist, porter, buggy, wheelchair, concierge bundles) is registered by this release beside FASTTRK. FNB (dining: restaurant reservations; aliases REST, DINING, RESTAURANT, RESTAURANTS; category DO, money model FREE, artifact CONF_NUMBER, served under the dining service key with base path /v1/dining) is registered since v1.7.0. GIFT (gift cards; category SUPPORT, money model MERCHANT, artifact VOUCHER, served under the gift-cards service key with base path /v1/gift-cards) is described from v1.31.0: until the backend seam change merges, domain GIFT answers 400 UNKNOWN_DOMAIN. AICONT (the Example Content experience-scraping service's operations; category DO, money model MERCHANT, artifact NONE, served under the aicont service key with base path /v1/aicont; a content supplier) has its typed intent from v1.39.0; it answers only where its supplier set is landed and ACTIVE. PARK (airport and cruise-port parking; aliases PRK and PARKING; category SUPPORT, money model MERCHANT, artifact CONF_NUMBER — the supplier's gate barcode is the order's BARCODE document — served under the parking service key with base path /v1/parking) has its typed intent and its verb book from v1.55.0.

    Opt-in enrichment on shopping answers: EMISSIONS | RATINGS | AMENITIES | ROUTE. Absent = the tenant's configured default. Decoration reads cache or the pre-warmed store only and never delays the verb.

    Ask for the supplier's own answer, verbatim, beside what the platform read from it: Offer.upstream on every offer of a search, poll, detail or flight-returns answer, AirReturnOption.upstream on each listed return, RepriceResponse.message.upstream and OrderItem.upstream. Served only where the deployment enables upstream pass-through; elsewhere a true value is 400 VALIDATION details.reason UPSTREAM_PASS_THROUGH_DISABLED, details.field context.includeUpstream, before any supplier call. Absent or false, nothing changes. The block is informational: offerRef, repriceRef and price stay the only handles and the only price of record.
  • selectionSelectionPreferencesOptional
    context.selection: the caller's offer-selection preferences for this search.Show more

    context.selection: the caller's offer-selection preferences for this search. Each field set here replaces the tenant's and the platform's for this search, within the caller's entitlements and the platform's ceilings, unless the tenant has locked request overrides. It never widens reach: a preferred supplier the caller may not reach is ignored with context.warnings[] SELECTION_PREFERENCE_IGNORED. Ignored where selection is off.

    Who a desk or agent books FOR: stamped into the audit actor and the clientReference lineage of the order.Show more

    Who a desk or agent books FOR: stamped into the audit actor and the clientReference lineage of the order. Send customerId (a customer or traveller id the tenant knows) or traveler (a free-text identity), or both. Attribution only: it grants nothing, and the credential's own actor is still what authorises the call. Audit mapping: the audit actor.onBehalfOf (a string) is customerId when present, otherwise "traveler:<redacted-hash>" (a stable hash of traveler, never the text).

    Consent-first: acceptedPenalty is the penalty the traveller agreed to, from the cancel-quote. A cancel without it cancels nothing and is answered 409 PENALTY_CHANGED with details.penalty (the current one) and details.requoteRequired true; a current penalty other than the accepted one is the same 409 with details.previousPenalty.

  HOME_REGION_REDIRECT: this tenant's writer region is not the region that received the request. Nothing was executed at this region. There is no body. Clients MUST NOT auto-follow this redirect: a cross-origin redirect makes most HTTP stacks drop the Authorization header, and some drop Location altogether. The client MUST re-send the same request (method and body unchanged) to Location WITH its credentials and the SAME Idempotency-Key. Follow-up sends are deduplicated on the Idempotency-Key in the home region.

  PENALTY_CHANGED | CONFLICT. PENALTY_CHANGED — the penalty moved against the one the client accepted, or (details.reason CONTRADICTS_BOOKED_TERMS) the supplier's penalty contradicts the cancellation terms the order was booked on, before any consent is read. CONFLICT — the order's state forbids a cancel: it is over, it has no supplier locator yet, or it is PENDING_RECONCILIATION (details.state names it). A cancel sent without intent.acceptedPenalty cancels nothing: it is PENALTY_CHANGED with details.penalty (the current penalty) and requoteRequired true, so consent always comes first. QUOTE_EXPIRED — the cancelQuoteRef is past its validUntil; re-quote. IDEMPOTENCY_CONFLICT | IDEMPOTENCY_IN_PROGRESS.

  PERMISSION_DENIED with details.reason KEY_PAUSED: the API key is PAUSED and every call with it is refused until an Owner or Admin resumes it (POST /v1/keys/{keyPrefix}:resume, a person only); or details.reason LOOP_DETECTED on the call whose loop paused the key (20 identical requests in 60 s, or 50 holds without a booking or release in 10 min; replays of one Idempotency-Key never count). Not retryable; nextAction stop — the agent stops using the key and tells the person; details carry resumeBy (owner), consoleLink and evidence (ApiKeyPauseEvidence). Nothing was charged, held or sent; holds and orders already made are untouched. A key whose ancestor (the key that minted it, or that key's minter) is PAUSED answers the same 423 KEY_PAUSED, and resuming the ancestor resumes it, so a child never outlasts a pause of its parent. The MCP plane answers the identical body as an isError result. Any key-authenticated route may answer it; it is declared on the order and hold writes, search, reprice and the key routes.

  RATE_LIMITED with details.reason VELOCITY_LIMIT: a soft breach of the API key's own scope (reqPerSec, holdsPerHour, cancelsPerDay, lookToBook, spendPerDay) — the first two in 24 hours; the third, or a burst above 5× the limit, pauses the key instead (423 KeyPaused). Retryable after retryAfterMs (mirrored by Retry-After); nextAction slow_down; details carry limit, windowSeconds and the dimension in details.field. The tenant quota of RateLimited and the key's velocity are separate limits. Every call of a minted key also counts against each ancestor key's velocity and spend windows, so minting N children never multiplies the blast radius; spendPerDay is reserved atomically before the order is placed and released if it fails.

  INTERNAL — a bug, traceId the support handle; or, on this verb, details.reason FX_SNAPSHOT_UNAVAILABLE: the supplier stated the servicing figures in a currency the order's own booked FX snapshot cannot convert to the order's currency, so they are not shown in another currency (drop-and-count) and nothing is cancelled: the refusal comes before any supplier commit.
