# AirPrice Reference Payload The AirPrice API confirms pricing on air search results. While air pricing is generally an optional but recommended step, it is required for low cost carriers and some NDC carriers. This API uses a reference payload request, which sends identifiers from the Search API response. To use the AirPrice reference payload request, your initial Search request must send offersPerPage to invoke caching if that Search was journey-based (leg-based search results are always cached). Endpoint: POST /air/price/offers/buildfromcatalogproductofferings Version: 11.36.0 Security: bearerAuth ## Security: - `bearerAuth` (unknown) http bearer JWT ## Header parameters: - `travelportPlusSessionIdentifier` (string) travelportPlusSessionIdentifier used to maintain an established agency session - `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 - `TVP-PCC-Core` (string) Allows user to pass PCC instead of Access Group ID ## Request body: - `application/json` (unknown) AirPrice Reference Payload request payload. ## Request fields (application/json): - `@type` (string, required) Discriminator. No child classes Example: OfferQueryBuildFromCatalogProductOfferings - `PaymentCriteria` (object) Optional object to send the BIN/INN (IssuerIdentificationNumber) of the credit card to be used for payment; sending the BIN returns OB fees in the response Required when using Air Canada flight pass. - `PaymentCriteria.@type` (string, required) discriminator Example: PaymentCriteria - `PaymentCriteria.IssuerIdentificationNumber` (string) Required if PaymentCriteria sent; 6 to 16 characters inclusive are accepted.

Example: ["www.travelport.com/uri"] - `PaymentCriteria.FlightPass` (array) In Search API, for NDC flight pass bookings this is a required field and must reference the owner in PassengerCriteria. Only one permitted per Search request. Required when using a flight pass to pay for an Air Canada NDC booking. Only one instance allowed. Refer to the [Air Canada Flight Pass](https://developer.travelport.com/docs/flights/ndc/ndc-guide-for-air-canada-flight-pass) section of the NDC Guide for more information - `PaymentCriteria.FlightPass.@type` (string, required) Discriminator. No child classes Example: FlightPass - `PaymentCriteria.FlightPass.accountNumber` (string, required) The flight pass account number. Example: 0140851633093 - `PaymentCriteria.FlightPass.supplier` (string, required) The flight pass supplier code. AC is the only value accepted at this time. Example: AC - `PaymentCriteria.FlightPass.Description` (array) - `PaymentCriteria.FlightPass.TravelerIdentifierRef` (array) In Search, use the passengerCriteriaRef to reference the owner of the flightpass. This is a mandatory field for Search API. - `PaymentCriteria.FlightPass.TravelerIdentifierRef.value` (string) Example: traveler_001 - `PaymentCriteria.FlightPass.TravelerIdentifierRef.id` (string) A locally referenced ID Example: id_001 - `PaymentCriteria.FlightPass.TravelerIdentifierRef.description` (string) Descriptive text used to identify the contents of a target object Example: Descriptive Text - `PaymentCriteria.FlightPass.TravelerIdentifierRef.uris` (array) Uniform Resource Identifier Example: ["www.travelport.com/uri"] - `PaymentCriteria.agencyAccountInd` (boolean) If true, payment will be made by agency account Example: true - `PaymentCriteria.bspInd` (boolean) If true, payment will be made by BSP Example: true - `PaymentCriteria.cashInd` (boolean) If true, payment will be made by cash Example: true - `PaymentCriteria.invoiceInd` (boolean) If true, payment will be made by invoice Example: true - `BuildFromCatalogProductOfferingsRequest` (object) Used to reference Air Search requests, such as for a Next Leg, reference-payload Price and Add Offer, or other reference-based calls. Defines the identifiers and selections needed to continue a workflow from a preceding Search response, including the cached search result id and the chosen offer and product to carry forward into the next request. - `BuildFromCatalogProductOfferingsRequest.@type` (string, required) Discriminator. Child classes BuildFromCatalogProductOfferingsRequestAir, BuildFromCatalogProductOfferingsRequestAirSearch, and BuildFromCatalogProductOfferingsRequestAirChange Enum: "BuildFromCatalogProductOfferingsRequestAir" - `BuildFromCatalogProductOfferingsRequest.CatalogProductOfferingsIdentifier` (object, required) Used to identify a cached Air Search result for subsequent reference-payload requests. Defines the transaction identifier returned from Search that is sent in later steps (such as Next Leg Search and other workflows) to reference a prior search response. The Search response does not return the CatalogProductOfferings/Identifier object if caching is not invoked with offersPerPage in the Search request. A subsequent reference payload request to those search results cannot be sent without caching and the CatalogProductOfferings/Identifier value. - `BuildFromCatalogProductOfferingsRequest.CatalogProductOfferingsIdentifier.id` (string) Local identifier within a given message for this object. Example: cpo_1 - `BuildFromCatalogProductOfferingsRequest.CatalogProductOfferingsIdentifier.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). - `BuildFromCatalogProductOfferingsRequest.CatalogProductOfferingsIdentifier.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. Example: A0656EFF-FAF4-456F-B061-0161008D7C4E - `BuildFromCatalogProductOfferingsRequest.CatalogProductOfferingsIdentifier.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. Example: TVPT - `BuildFromCatalogProductOfferingsRequest.CatalogProductOfferingSelection` (array, required) - `BuildFromCatalogProductOfferingsRequest.CatalogProductOfferingSelection.@type` (string) Discriminator.

If any price modifiers are sent in the AirPrice reference payload request, all cached Search modifiers are discarded and only the modifiers sent in that AirPrice request are used. - For the Add Offer request, you may optionally store fares with one or more pricing modifiers. If a pricing modifier is not added, the auto stored fare is added to the reservation. There is no change in the AirReservation response when pricing modifiers are requested. AirReservation applies modifiers from Add Offer and earlier steps as follows: - Modifiers sent in the Add Offer request (supported for both full and reference payload). - If no modifiers are sent in Add Offer, any pricing modifiers sent in AirPrice are applied. - If no modifiers were sent in AirPrice, or if AirPrice was not sent, any pricing modifiers sent in Search are applied. GDS only; pricing modifiers not supported for NDC. If the requested modifier does not have any fares associated with it, the workbench commit fails and returns the error message 'No Fare Found'.

The response returns an instance of TermsAndConditions/OrganizationInformation/OrganizationIdentifier for each account code sent. When FareSelection/fareType=PrivateFaresOnly and an account code is sent in OrganizationIdentifier, AirPrice ignores the account code. Instead, AirPrice returns any private fares available for that market and a booking code for your PCC. This prevents the return of an error message when no specific fare has been filed for that account code. - `BuildFromCatalogProductOfferingsRequest.PricingModifiersAir.OrganizationInformation.OrganizationIdentifier.value` (string) The value of the code to apply.

If sending multiple account codes, send each instance with accountCodeFaresOnlyInd set to true. - If false (default behavior): does not limit fares returned to any account code sent. If an account code is sent without accountCodeFaresOnlyInd=true, the response includes any fares filed for that account code plus fares that are not specific to the account code. If accountCodeFaresOnlyInd=true and no account code is sent, the indicator is ignored and the response returns all fares and a warning message that the request must include an account code. Note the following when also requesting private fares only: - FareSelection/fareType=PrivateFaresOnly and account code: Private fares are returned. - FareSelection/fareType=PrivateFaresOnly, accountCodeFaresOnlyInd=true, and account code: Any private fares specific to that account code are returned if available.

Split ticketing is available only for customers specifically provisioned for split ticketing. If your account is not configured for split ticketing, sending includeSplitPaymentInd returns a response without split ticket offers and a warning message. Requests request split ticketing, which returns outbound and inbound one-way fares in addition to round trip options in the Search API response. This may result in lower fares than the same or similar round-trip itinerary. - If true: requests split ticketing. - If false (default behavior): split ticketing options are not returned. When split ticketing is requested, the Search response returns offers in the following order: - Outbound one-way offers - Inbound one-way offers - Round trip offers The response identifies all one-way outbound and inbound offers with CombinabilityCode j0. CombinabilityCode values for round trip offers start at j1 and increment by one for each offer. Only the following are supported for split ticketing: - Search (not supported for Next Leg Search or Flight Specific Search) - Round-trip journey-based offerings ( isJourney header not sent or sent as true, or CustomResponseModifiersAir/SearchRepresentation not sent or sent with value Journey) - Upsells. Split ticketing is not supported for round-trip leg-based searches, virtual interlining, or NDC. Split ticketing returns one-way outbound and one-way inbound fares in addition to round-trip offers. Split ticket offers are identified with CombinabilityCode j0. In Air Price: for split ticketing the request must send offers that are identified in the Search response with CombinabilityCode j0, which identifies those offers as one-way outbound and one-way inbound split ticketing offers. A combination of j0 and any non-j0 value offer returns an error message that split pricing is not supported. - `BuildFromCatalogProductOfferingsRequest.PricingModifiersAir.returnMostRestrictiveBrandInd` (boolean) GDS only, not supported for NDC. In Search API, when there are different brands on a connecting flight, return information for either the most restrictive brand or the brand on the most significant segment on the itinerary. - If true: return the offer brand of the most restrictive brand. - If false (default behavior): return the offer brand of the most significant segment of the itinerary. - `BuildFromCatalogProductOfferingsRequest.PricingModifiersAir.splitPaymentOfferings` (number) Number between 0 and 99. Send with includeSplitPaymentInd to configure the percentage of round trip offers to return in a split ticketing response. By default, Search divides the split ticketing response into 34% round-trip offerings and the remainder as split ticketing offers, which are combined outbound and inbound one-way fares. To change this percentage, send splitPaymentOfferings with the percentage value of round trip offers to return. Example: 25 - `BuildFromCatalogProductOfferingsRequest.PricingModifiersAir.Brand` (object) Information on airline Brand offerings. If brand attributes were not excluded with inhibitBrandContentInd=true (GDS only), then brand attributes are returned and consolidated in ReferenceList/ReferenceListBrand.

Only one cabin preferenceType (Permitted, Preferred, PreferredWithUpgrade) is allowed per request, but there is no limit to the number of cabins that can be sent. - Any CabinPreference in the initial Search request is applied to any subsequent Next Leg Search and reference Flight Specific Search requests. - By default, the CabinPreference in the initial Search request is also applied to any subsequent Next Leg Search request. To override this default and return all cabins for the next leg in the response, send ignoreCabinPreferenceInd=true in the Next Leg Search request. - In AirPrice and AirReservation (Supported for Full Payload path only) - If CabinPreference was sent in the Search request, it is cached and sent with the AirPrice reference payload request. If CabinPreference is sent in the AirPrice request, all cached modifiers are discarded and only the modifiers sent in the AirPrice request are used. Can be combined with lowFareFinderInd=true to return lowest fare in the requested cabin or cabins. When using CabinPreference and lowFareFinderInd, if both CabinPreference and a class of service are sent, class of service is ignored. If CabinPreference is sent without a class of service, the response returns the lowest fare in the cabin requested. If that cabin is not available, the response may upgrade or downgrade to a different cabin. If a different cabin than requested is returned, the response returns the message that the cabin class may differ from the class requested. If lowFareFinderInd=false and CabinPreference are sent in the request, AirPrice ignores the preferred cabin and returns a message that the preferred cabin was ignored. If CabinPreference is set to All, no cabin preference is applied. - `BuildFromCatalogProductOfferingsRequest.CabinPreference.@type` (string, required) Discriminator. No child classes exist Example: CabinPreference - `BuildFromCatalogProductOfferingsRequest.CabinPreference.preferenceType` (string) Type of cabin preference. Sending a mix of preferenceType values is not supported. For example, you cannot send an instance of CabinPreference with a preferenceType of Permitted and another instance with preferenceType of Prohibited. In this case the results default to the Preferred preference. Note that if lowFareFinderInd is sent with true and CabinPreference is sent, the only supported value for CabinPreference/type is Permitted. Enum: "Preferred", "Permitted", "PreferredWithUpgrade", "Prohibited" - `BuildFromCatalogProductOfferingsRequest.CabinPreference.cabins` (array) A space-delimited list of cabins. - `BuildFromCatalogProductOfferingsRequest.CabinPreference.legSequence` (array) Leg level preference is supported only for CarrierPreference, CabinPreference, and ClassOfServicePreference. Not supported at AirPrice or Book. Limits preference to the specified leg. You can apply the preference to only some legs of the itinerary, or different preferences to different legs. Best practice is to also send legSequence in SearchCriteriaFlight. To apply preference to the entire itinerary, do not send legSequence. Example: [1,2] - `BuildFromCatalogProductOfferingsRequest.FareRuleCategory` (array) Not recommended use. Invoke fare rule end points directly. - `BuildFromCatalogProductOfferingsRequest.FareRuleType` (string) Use not recommended; request fare rules using the Fare Rules API request instead. Returns fare rules in the offer response. Structured rules limit the rules returned to one or more of these categories: advance reservation/ticketing requirements, minimum/maximum stay, stopovers, penalties, voluntary exchanges and refunds. GDS supports all categories; NDC supports only penalties. See the [Fare Rules Guide](https://developer.travelport.com/docs/flights/guides/fare-rules-guide) for details. Note that even if fare rules are not requested, for GDS only, change and cancel penalties are returned unless suppressed by sending CustomResponseModifiersAir/excludePenaltiesInd set to true.

Example: [1,2] - `BuildFromCatalogProductOfferingsRequest.CustomResponseModifiersAir.BrandAttributeInclusion.Classification` (array) Send one or more of the supported values to return information about only the specified attributes. Fares may include other attributes but information about them is not returned. - `BuildFromCatalogProductOfferingsRequest.CustomResponseModifiersAir.BrandAttributeInclusion.AdditionalClassification` (array) Send one or more of the additional supported values to return information about only the specified additional attributes. Supported values: - ChauffeurTransfer - ExtraLegroom - InFlightEntertainment - LoungeAccess - PriorityBaggage - PriorityBoarding - PriorityCheckIn - PrioritySecurity - PriorityServices - MileageAccrual - Upgrades - USB - `BuildFromCatalogProductOfferingsRequest.CustomResponseModifiersAir.SearchRepresentation` (string) Specifies either a journey or leg-based response.This setting does not affect one-way itineraries, which have one leg and are always journey-based. - Journey returns offers for all legs of the itinerary. Journey is the default. - Leg returns offers for only the first leg of the itinerary. Must be followed with a Next Leg Search to select an offer for the first leg and return offers on the subsequent leg to combine with it. Customize search result set as leg or journey based. Next Leg Search requests, and Flight Specific Search requests for less than the full itinerary, are supported only after a leg-based Search, not a journey-based Search. If these requests follow a journey-based Search request, an error message is returned. Enum: "Leg", "Journey", "LegWithJourneyData" - `BuildFromCatalogProductOfferingsRequest.CustomResponseModifiersAir.excludePenaltiesInd` (boolean) GDS only; not supported for NDC. Indicator to omit change and cancel penalties. - If true: omits all penalty information from the response. - If false (default behavior): returns any change and penalty details provided by carrier for each offer in TermsAndConditionsFullAir/Penalties. If sent in Search but not in AirPrice, the value sent in Search is cached and applied to the AirPrice results. However, you can override the value sent in Search by sending excludePenaltiesInd in the AirPrice request with the opposite value. For example, if the Search request sends excludePenaltiesInd=true and the AirPrice request sends excludePenaltiesInd=false, the Search response does not return penalties and the AirPrice response does return penalties. Example: true - `BuildFromCatalogProductOfferingsRequest.CustomResponseModifiersAir.excludeBaggageFeesInd` (boolean) GDS only; not supported for NDC. Indicator to exclude baggage details. - If true: excludes baggage fees, carry on fees, and embargo information from the response. Baggage quantity or weight is returned instead. - If false (default behavior): baggage details returned in response. Default is false. Example: true - `BuildFromCatalogProductOfferingsRequest.CustomResponseModifiersAir.includeFareCalculationInd` (boolean) GDS only; not supported for NDC or in the Flight Specific Search full payload request. Indicator to request the return of the fare calculation ladder. - If true: returns the fare calculation ladder in BestCombinablePrice.PriceBreakdownAir.FareCalculation. - If false (default behavior): fare calculation ladder is not returned. Example: true - `BuildFromCatalogProductOfferingsRequest.CustomResponseModifiersAir.excludeSurchargesInd` (boolean) GDS only; not supported for NDC. Indicator to exclude a surcharge breakdown. - If true: excludes a surcharge breakdown from the response. Baggage quantity or kilos is returned instead. - If false (default behavior): surcharge breakdown returned in response. Example: true - `BuildFromCatalogProductOfferingsRequest.CustomResponseModifiersAir.excludeUnbundledFaresInd` (boolean) GDS only, not supported for NDC. Sets whether to return unbundled fares. Supported in AirSearch and AirPrice. - If true: does not return unbundled fares. - If false (default behavior): returns unbundled and bundled fares as available. Example: true - `BuildFromCatalogProductOfferingsRequest.CustomResponseModifiersAir.includeCO2EmissionsDataInd` (boolean) Indicator to return CO2 emission data in the Search and Next Leg Search responses. - If true: returns CO2 emission data. - If false (default behavior): CO2 emission data not returned. Example: true - `BuildFromCatalogProductOfferingsRequest.CustomResponseModifiersAir.includeFlightAmenitiesInd` (boolean) Indicator to return flight amenities from ATPCO RouteHappy data. - If true: includes amenities in the response if available. - If false: Does not return ATPCO RouteHappy amenities. Example: true - `BuildFromCatalogProductOfferingsRequest.CustomResponseModifiersAir.includeUniversalProductAttributesInd` (boolean) Indicator to return universal product attributes (UPAs), which include images, icons, and URLs as provided by ATPCO. Must also send includeFlightAmenitiesInd=true. - If true: returns universal product attributes if available. - If false (default behavior): Universal product attributes not returned. UPAs are not returned for direct flights with intermediate stops, non-flight segments such as trains, or for Premium Business class. Example: true - `BuildFromCatalogProductOfferingsRequest.CustomResponseModifiersAir.includeBundledAncillariesInd` (boolean) NDC only; not supported for GDS. If true: request NDC offers that include an ancillary service bundled with the cost of the air fare. This could be a discounted paid seat or any other ancillary service offered by the carrier. Search and Price responses will contain both ProductAir and ProductAncillary plus a new child class of PriceBreakdown, PriceBreakdownAncillaryAir, to define the ancillary inclusion and pricing. Example: true - `BuildFromCatalogProductOfferingsRequest.CustomResponseModifiersAir.includeFullPenaltyDisclosureInd` (boolean) GDS only. For NDC, change and cancel penalties are returned by the NDC carrier. Indicator to return ATPCO Cat31 and Cat33 penalties in the response in TermsAndConditions/Penalties in Change and Cancel. - If true: returns penalty information sourced from ATPCO Cat 31 and 33. Penalties may be exposed at fare component level and include time windows. - If false (default behavior): Cat 31 and 33 penalties are not returned. The most restrictive Cat 16 penalties are returned. When specified in the Search request, this indicator is applied to Reference Payload Flight Specific Search as well. - `BuildFromCatalogProductOfferingsRequest.lowFareFinderInd` (boolean) GDS only; not supported for NDC. Provides pricing flexibility around class of service. If not sent, the response returns fares only in the requested class of service. - If true: returns the lowest fares available in any class of service available, which may not be the same as the requested class. Note that if lowFareFinderInd is sent with true and CabinPreference is sent, the only supported value for CabinPreference/type is Permitted. - If false: Provides fares for only the specified class of service. Default. When lowFareFindInd=true and brand attributes are not disabled (inhibitBrandContentInd), AirPrice uses only the brand tier (and any other pricing modifiers) to find the lowest fare within a brand tier regardless of class of service. Example: true - `BuildFromCatalogProductOfferingsRequest.reCheckInventoryInd` (boolean) If true, verifies availability for the requested number of passengers in a specific class of service at the time of the price request by booking and releasing seats. Because this indicator temporarily affects seat availability, the recommended best practice is to use validateInventoryInd instead. Some airlines monitor for high volumes of sell/ignore transactions. Regardless of pricing results, air fares and inventory are only guaranteed by airlines when ticketed and paid. Can help reduce sell failures at booking by alerting of insufficient availability. If any or all segments are not bookable, AirPrice does not return any offers and returns an error message. GDS only, not supported for NDC (NDC carriers always validate inventory at pricing). Example: true - `BuildFromCatalogProductOfferingsRequest.inhibitBrandContentInd` (boolean) If true, disables the return of branded fare attributes. By default the AirPrice Reference Payload request returns branded fare attributes. Example: true - `BuildFromCatalogProductOfferingsRequest.validateInventoryInd` (boolean) Verifies availability and may reduce failures at the Add Offer and Workbench Commit steps. If true, verifies availability for the requested number of passengers in a specific class of service at the time of the price request. If there are fewer seats than requested passengers available in that class of service, AirPrice returns an error message and no offers. GDS only, not supported for NDC (NDC carriers always validate inventory at pricing). Example: true - `MaxNumberOfUpsellsToReturn` (integer) NDC only; not supported for GDS. Supports values from 0 to 99 inclusive. Send to request upsell offers along with pricing for the requested class of service or cabin, returned in ascending price order. An upsell is the next highest fare in a different brand or cabin than requested. Upsells are returned as follows: - If upsells not requested: Only the requested offer is returned. - If one upsell requested: The lowest priced offer in the requested class of service or cabin plus one upsell offer are returned. - If two or more upsells requested: The lowest priced offer in the requested class of service or cabin plus the requested number of upsell offers are returned. Example: 4 ## Request examples: - `NDC request with organization information - account code` (unknown) - `NDC with SellCity pricing modifier` (unknown) - `OB fees charged based on credit card BIN` (unknown) - `NDC with CustomerLoyalty` (unknown) ## Response 200: - `200` (unknown) OK - Successful Response - 200 ## Response 200 fields (application/json): - `OfferListResponse` (object) The response of an Offer list endpoint request, such as AirPrice and Add Offer calls.

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.

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. Example: A0656EFF-FAF4-456F-B061-0161008D7C4E - `OfferListResponse.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.
