NDC Solutions source code provides airlines and sellers a means of connecting via a single API. There are two types of sellers accessing airline content via NDC, IATA/ARC (Airline Reporting Corporation) Accredited seller (also known as, agency-driven flow) and Non-IATA/ARC Accredited seller (also known as, consumer-driven flow).

IATA/ARC Accredited

For requests for airline content from IATA/ARC Accredited sellers, IATA_Number and AgencyID must be provided in each request, as shown in the XML code snippet below. IATA_Number determines the location and currency to be applied. AgencyID is the assigned identification number for a specific travel agency and can be an IATA or non-IATA number.

📝 Sellers are issued specific test credential codes for the sandbox (i.e., test environment) by the airline. Do not use any IATA codes that are used in the provided examples. In a production environment, sellers use their accredited IATA code(s).

Non-IATA/ARC Accredited

For requests for airline content from Non-IATA/ARC Accredited sellers, IATA_Number should not be included in the request, as shown in the XML snippet below.

CountryCode is required for the Non-IATA/ARC Accredited seller and defines the currency, as seen in the below XML code snippet. The ability to change the currency (i.e., override) for the Non-IATA/ARC Accredited seller is based on CountryCode, which must be the same throughout the entire workflow (e.g., AirShopping through OrderCancel). CountryCode is not required for the IATA/ARC Accredited seller.

    <PointOfSale>
        <Location>
            <CountryCode>US</CountryCode>
        </Location>
    </PointOfSale>
    <Parameters>
        <Languages>
            <LanguageCode>en-CA</LanguageCode>

                <CurrCode>USD</CurrCode>
            </FiledInCurrency>
        </CurrCodes>
    </Parameters>

There are a limited number of currencies and country codes supported by the Non-IATA/ARC Accredited seller (see the Country and Currency table below). Currency codes and country codes not included in the below table will result in errors. Permitted currencies are associated with your airline's credentials.

📝 Not including required information throughout the NDC workflow will result in errors. For example, the same IATA_Number and CountryCode should be used throughout your message requests.
