Select one of the following pass verticals to learn more about how it can be used.


This section contains code snippets for offers. It covers the following classes and objects:

JSON OfferClass

Once you have defined the OfferClass, insert it by making a POST request to the following REST URI:

https://walletobjects.googleapis.com/walletobjects/v1/offerClass

Add the strict=true parameter to the REST URI to enable strict error parsing and catch additional errors, such as duplicate ID fields:

https://walletobjects.googleapis.com/walletobjects/v1/offerClass?strict=true

The following example shows a JSON resource representing an OfferClass. The JSON must be sent in the body of the POST request. Specifically, the following code samples demonstrate defining and inserting the OfferClass.

JSON OfferObject

The following samples define the OfferObject:

  "classId": "2945482443380251551.OfferClass",
  "id": "2945482443380251551.OfferObject",
  "state": "active",
  "barcode": {
    "kind": "walletobjects#barcode",
    "type": "upcA",
    "value": "123456789012",
    "alternateText": "12345"

    "end": {
      "date": "2013-12-12T23:20:50.52Z"
      }
  }
}

Java

// Define Barcode
Barcode barcode = new Barcode().setType("upcA").setValue("123456789012")
    .setAlternateText("12345");

// Define Wallet Object
OfferObject object = new OfferObject()
	.setClassId('2945482443380251551.ExampleOfferClass1')
    .setId('2945482443380251551.ExampleOfferObject1')
    .setBarcode(barcode)
    .setValidTimeInterval(new TimeInterval().setEnd(new DateTime().setDate(new com.google.api.client.util.DateTime(
            new Date().getTime() + 263000000000L))))
    .setState("active");

PHP

$barcode = new Google_Service_Walletobjects_Barcode();

Python

offer_object = {

          'alternateText': '12345'
      }
  }

There are two ways to insert the OfferObject.

The first way is to make a POST request (with defined object in body) to the following REST URI:

https://walletobjects.googleapis.com/walletobjects/v1/offerObject

The second way is to create a JWT from the OfferObject definition and putting the JWT in a Save to Google Pay button. For more information, see Add a web button.

Add OfferObject using Android API

The following example OfferObject can be inserted using the Android API wallet SDK package:
