Add a flight journey with multiple legs

Stay organized with collections Save and categorize content based on your preferences.

Often, one flight journey includes multiple legs rather than a direct journey to a person's destination. During this journey, airlines issue one boarding pass per leg of the journey. The Google Wallet API supports this behavior through the use of individual FlightObject instances per leg.

For example, if you have two passengers who fly from SFO to LAX to TPE, there would be two FlightClass instances (one per passenger) and four FlightObject instances (two per passenger).

Passenger FlightClass A (SFO -> LAX) FlightClass B (LAX -> TPE)
J. Smith FlightObject (id_jsmith_1) FlightObject (id_jsmith_2)
J. Doe FlightObject (id_jdoe_1) FlightObject (id_jdoe_2)

These fields reflect the same values as a physical boarding pass.

There are a number of scenarios where a user may purchase multiple tickets at the same time, such as the following:

  • Multiple flights
  • Trips with layovers
  • Purchasing for family members

In these situations, it's useful to allow a user to add many boarding passes to their Google Wallet app at the same time. You can define multiple objects or classes in a JSON Web Token (JWT), which can then be used to create an Add to Google Wallet button or link. When the user clicks the button, it will add all defined passes to the user's device at the same time.

In the JWT to be signed, include pass classes and objects in the flightClasses and flightObjects arrays of the payload property, respectively. The following examples show two variations on how to do this.

For more information on the UI representation of multiple passes, see Group multiple Boarding passes.

Existing classes and objects

This example uses pre-created classes and objects and only requires the IDs of each. Note that the classId property is optional for the pass objects. It is shown here for demonstrative purposes.

{
    "aud": "google",
    "origins": [],
    "iss": "your_iam_account@appspot.gserviceaccount.com",
    "iat": 1534891254,
    "typ": "savetowallet",
    "payload": {
        "flightObjects": [
            {
                "classId": "issuerId.flightClassSuffix",
                "id": "issuerId.flightObjectSuffix_01"
            },
            {
                "classId": "issuerId.flightClassSuffix",
                "id": "issuerId.flightObjectSuffix_02"
            }
        ]
    }
}

Create new classes and objects

This example defines a class and multiple child objects. Both the class and objects are created by Google Wallet only when the user clicks the Add to Google Wallet link and adds the passes to their device.

                "reservationInfo": {
                    "confirmationCode": "ABC123"
                }
            },
            {
                "id": "issuerId.flightObjectSuffix_2",

            }
        ]
    }
}
