# Unified Checkout Booking As an alternative to the booking workflow that takes place in a workbench session, you can send all booking details and commit a single payload to create a booking. The single payload book request does not support any of the optional steps in the booking workflow, such as adding seats or ancillaries. Endpoint: POST /air/book/reservation/reservations/build Version: 11.36.0 Security: bearerAuth ## Header parameters: - `TraceId` (string) Identifier used to correlate Air API invocations across a multi-call business flows. - `XAUTH_TRAVELPORT_ACCESSGROUP` (string) Identifies the Travelport access group with which the caller is associated - `travelportPlusSessionIdentifier` (string) travelportPlusSessionIdentifier used to maintain an established agency session - `TVP-PCC-Core` (string) Allows user to pass PCC instead of Access Group ID ## Request fields (application/json): - `ReservationQueryBuild` (object) Used for a Create Hotel Reservation (Reference Payload) request. Defines a request to create a hotel reservation using selected hotel offer data together with traveler and payment details. This request typically follows Hotel Availability, Rules, or SearchComplete and is sent to finalize a booking. If the price or guarantee type changes from the preceding response, the request may need to be sent again with the applicable acceptance indicator. - `ReservationQueryBuild.@type` (string, required) Discriminator class ReservationQueryBuild only Example: ReservationQueryBuild - `ReservationQueryBuild.ReservationBuild` (object, required) Defines the reservation build details used to create a single payload reservation, including traveler, payment, and related booking details. For Hotel use ReservationBuildFromCatalogOffering schema. For Air use ReservationBuildFromCatalogProductOfferings (reference payload) or ReservationBuildFromProducts (FullPayload)." - `ReservationQueryBuild.ReservationBuild.@type` (string, required) Discriminator classes ReservationBuildFromCatalogOffering, ReservationBuildFromCatalogOfferings, ReservationBuildfromCatalogOfferingsAir, ReservationBuildFromCatalogProductOfferings, ReservationBuildFromProducts, ReservationBuildVehicle Example: ReservationBuildFromProducts - `ReservationQueryBuild.ReservationBuild.autoDeleteDate` (string) Creates a retention segment to keep the host PNR alive until this date. Example: 2011-01-24 - `ReservationQueryBuild.ReservationBuild.receivedFrom` (string) Allows the user to specify who the request was received from. Example: TW - `ReservationQueryBuild.ReservationBuild.issuance` (string) Mid/BackOffice instructions. Enum: "Ticket", "BackOffice", "All", "Invoice" - `ReservationQueryBuild.ReservationBuild.Traveler` (array, required) - `ReservationQueryBuild.ReservationBuild.Traveler.@type` (string, required) Discriminator classes TravelerID or Traveler Example: Traveler - `ReservationQueryBuild.ReservationBuild.Traveler.id` (string) Send value of travelerRefId_1 for the first traveler, then increment for each additional traveler (e.g., travelerRefId_2). Traveler/id is only mandatory when referenced elsewhere in the request, such as in SpecialService and PrimaryContact (TravelerIdentifier/Identifier/value). - `ReservationQueryBuild.ReservationBuild.Traveler.TravelerRef` (string) - `ReservationQueryBuild.ReservationBuild.Traveler.Identifier` (object) A globally unique identifier key often used to reference a given option (such as Pricing, Booking, Rules, or additional workflows) or to retrieve information (such as Hotel pagination). - `ReservationQueryBuild.ReservationBuild.Traveler.Identifier.value` (string) Unique offer identifier that can be sent in subsequent payload requests to reference this offer. When used for reference flight calls, the CatalogProductOfferingsIdentifier will be the transaction identifier from the Search, Next Leg Search, or Flight Specific Search response in CatalogProductOfferings/Identifier/value. If you choose to pull the CatalogProductOfferingsIdentifier from the Price response instead (OfferListResponse/Identifier/value), either full or reference payload, please note for subsequent Add Offer requests you must remove the _PC appended to the end of the value in the AirPrice response (e.g., change value: '93d2091d-3d04-48ab-8091-6ae1525f02ea_PC' to value: '93d2091d-3d04-48ab-8091-6ae1525f02ea'). When building an AirPrice or Add Offer reference payload request: - Look for the CatalogProductOfferingIdentifier (ex: o1) in a Search response at CatalogProductOfferings/CatalogProductOffering/id or a Price response at OfferListResponse/OfferID/id. - Look for the ProductIdentifier (ex: p0) in a Search response at CatalogProductOfferings/CatalogProductOffering/ProductBrandOptions/ProductBrandOffering/Product/productRef or from a Price response at OfferListResponse/OfferID/Product/id. When returned from a workbench, this value is the system generated workbench identifier that must be sent in all subsequent requests for this workbench session. When returned from Air Exchange Eligibility, value is the ticket number sent with the eligibility request. When used specifically for form of payment, the value will begin with the characters 'FOP'. Similarly, the OfferIdentifier associated will begin with the character 'O'. - If not available, for Payment, any unique identifier can be sent. For Hotel Create Reservation (Reference Payload), send the value from the Availability response in CatalogOffering/id or the value from SearchComplete returned in propertyItems/lowestPublicAvailableRate/rateKey/value. Results from Hotel Availability and Hotel SearchComplete are stored in the cache for 30 minutes. If the offers expire before booking, you must send a new request.

For AirPrice, please note that GDS offers return the value 'Travelport' in authority while NDC offers return the carrier code of the issuing NDC carrier. When returned from Air Exchange Eligibility, authority is always 'Travelport' as the transaction issuer. For Hotels, authority indicates which supplier returned the lowest available rate for that property: either 'TVPT' (Travelport) or 'BKNG' (booking.com). Booking.com access requires additional provisioning and a direct agreement with the supplier. Authority is not returned if the property is closed or returns an error. For Hotel Create Reservation (Full Payload) and Sync Reservation send the value from the Availability response in CatalogOffering/Identifier/authority for the instance you want to book.

The structure detailed here is the same for all of these API responses. For Post-Commit Workbench Create and Workbench Retrieve the response is structured the same, plus a workbench identifier. The information returned in the Reservation Retrieve response varies depending on the information that has been added to the reservation at the time of retrieve, whether the reservation has been ticketed, and whether the reservation was created using the Travelport TripServices APIs or another program. Please note the requests for Workbench Commit (Create Reservation), Post-Commit Workbench Create, and Workbench Retrieve do not support the query parameters available in Reservation Retrieve and do not return the following: - any document override, accounting, historical, and DOCI remarks - any custom rules - brand attributes - baggage dimension and fee details - fare rules - ATPCO RouteHappy flight amenities For Two-step Commit: In the initial booking workflow, or when adding an offer to an existing reservation, or during an exchange, you can send enableTwoStepCommitInd=true to enable a two-step commit process that returns a warning if specific error scenarios occur.

If a Two-step Commit is triggered, the booking is not created and the first commit response returns objects that may not return in a typical commit response payload. The payload varies based on the warning that triggered the Two-step Commit, and may include additional objects if seats or other ancillaries were added to the workbench. Because the booking was not committed, Result/status is 'Not Processed'. A descriptive error or warning is returned in Result/Error/Message or Result/Warning/Message. The response to a second commit that creates a booking uses the same structure as a Reservation Retrieve response. - `ReservationResponse.Reservation` (object) Empty container to request workbench ID. In the response, this is the top-level object for reservation details. Generally includes the Identifier, Offer, Traveler, and ReservationDisplaySequence objects. Depending on the information in the reservation, may include Receipt, ReservationComment, PrimaryContact, CustomAuxiliarySegment. - `ReservationResponse.Reservation.@type` (string, required) Discriminator classes ReservationID, Reservation, or ReservationDetail Example: Reservation - `ReservationResponse.Reservation.id` (string) Internal identifier for the response.

When building an AirPrice or Add Offer reference payload request: - Look for the CatalogProductOfferingIdentifier (ex: o1) in a Search response at CatalogProductOfferings/CatalogProductOffering/id or a Price response at OfferListResponse/OfferID/id. - Look for the ProductIdentifier (ex: p0) in a Search response at CatalogProductOfferings/CatalogProductOffering/ProductBrandOptions/ProductBrandOffering/Product/productRef or from a Price response at OfferListResponse/OfferID/Product/id. When returned from a workbench, this value is the system generated workbench identifier that must be sent in all subsequent requests for this workbench session.
