# Add Multiple Travelers Send the Add Traveler request to add multiple travelers to the reservation workbench. Traveler information can include traveler name and contact details. Traveler information can include traveler name and contact details, add traveler-specific remarks including certain SSRs and travel documents such as a passport. Use air/book/traveler/reservationworkbench/{workbenchID}/travelers when adding exactly one traveler. Endpoint: POST /air/book/traveler/reservationworkbench/{ReservationResource_Identifier}/travelers/list Version: 11.35.2 Security: bearerAuth ## Path parameters: - `ReservationResource_Identifier` (string, required) The Reservation Identifier that you wish to add Travelers to ## Header parameters: - `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 - `travelportPlusSessionIdentifier` (string) travelportPlusSessionIdentifier used to maintain an established agency session - `TVP-PCC-Core` (string) Allows user to pass PCC instead of Access Group ID ## Request fields (application/json): - `Traveler` (array, required) - `Traveler.@type` (string, required) Discriminator classes TravelerID or Traveler Example: Traveler - `Traveler.id` (string) - `Traveler.TravelerRef` (string) - `Traveler.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). - `Traveler.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. 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 - `Traveler.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.
