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.

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 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.

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.

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 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.

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').

    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 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.

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').

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.

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').

- 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.

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 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.
