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.

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.
