Similarly, the OfferIdentifier associated will begin with the character 'O'. 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.

Similarly, the OfferIdentifier associated will begin with the character 'O'. 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.

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 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'. 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. Example: A0656EFF-FAF4-456F-B061-0161008D7C4E - `ErrorResponse.Identifier.authority` (string) Name of the supplier system that created this identifier - the source of information. 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.

Enum: "GET", "DELETE", "PUT", "POST" - `ErrorResponse.NextSteps.NextStep.description` (string) Additional clarification for the next step Example: remove offer from the order - `ErrorResponse.ReferenceList` (array) - `ErrorResponse.ReferenceList.@type` (string, required) Discriminator - Air Search child classes are ReferenceListAmenity, ReferenceListBrand, ReferenceListFlight, ReferenceListProduct, ReferenceListTermsAndConditions, and ReferenceListUniversalProductAttribute. - Air Price child classes are ReferenceListAmenity and ReferenceListBrand. - FareRules child class is ReferenceListFlight. - Search Ancillaries child class is ReferenceListFlight. - Seat Map child class is ReferenceListSeatingChart. - Hotel Availability child class is ReferenceListPropertyDates. - Reservation and Reservation Workbench child classes are ReferenceListAmenity, ReferenceListBrand, and ReferenceListUniversalProductAttribute. - Exchange Search child classes are ReferenceListBrand, ReferenceListFlight, and ReferenceListExchangedPrice. - Reservation Receipt child classes are ReferenceListOffer and ReferenceListTraveler. - Book_Traveler child class is ReferenceListTraveler. Example: ReferenceListFlight - `ErrorResponse.ReferenceList.id` (string) Uniquely identifies for the Reference List - `ErrorResponse.CurrencyRateConversion` (array) - `ErrorResponse.CurrencyRateConversion.@type` (string) - `ErrorResponse.CurrencyRateConversion.SourceCurrency` (object, required) Currency codes are the three-letter alphabetic codes that represent the various currencies used throughout the world.
