In standard booking workflows, this request is typically sent after Hotel Availability, Rules, or SearchComplete.

Additionally used for the response of Create Reservation (Reference Payload), Create Reservation (Full Payload), or Sync endpoint calls.

    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 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.

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.

    The response of a Create Reservation (Reference or Full Payload), Sync Reservation, Modify/Add Reservation, Create/Modify Passive Reservation, Retrieve Reservation, or Cancel Reservation endpoint.   The structure detailed here is the same as 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

  - `ReservationResponse.Reservation.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 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.

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.
