Pass type	File
Event tickets	demo_eventticket.php
Flight boarding passes	demo_flight.php
Generic passes	demo_generic.php
Gift cards	demo_giftcard.php
Loyalty program membership	demo_loyalty.php
Offers and promotions	demo_offer.php

Prerequisites

• PHP 7.4
• Composer 2.x
• Follow the steps outlined in the Google Wallet prerequisites to create the Google Wallet issuer account and Google Cloud service account

Environment variables

The following environment variables must be set. Alternatively, you can update the code files to set the values directly. They can be found in the constructor for each class file.

Enviroment variable	Description	Example
GOOGLE_APPLICATION_CREDENTIALS	Path to a Google Cloud service account key file	/path/to/key.json

How to use the code samples

1. Install the dependencies listed in composer.json

   # This must be run from the same location as the composer.json
   composer install

2. In your PHP code, import a demo class and call its method(s). An example can be found below

   // Import the demo class
   require __DIR__ . '/demo_eventticket.php';
   
   // Your Issuer account ID (@see Prerequisites)
   $issuerId = '3388000000000000000';
   
   // Create a demo class instance
   $demo = new DemoEventTicket();
   
   // Create a pass class
   $demo->createClass($issuerId, 'class_suffix');
   
   // Update a pass class
   $demo->updateClass($issuerId, 'class_suffix');
   
   // Patch a pass class
   $demo->patchClass($issuerId, 'class_suffix');
   
   // Add a message to a pass class
   $demo->addClassMessage($issuerId, 'class_suffix', 'header', 'body');
   
   // Create a pass object
   $demo->createObject($issuerId, 'class_suffix', 'object_suffix');
   
   // Update a pass object
   $demo->updateObject($issuerId, 'object_suffix');
   
   // Patch a pass object
   $demo->patchObject($issuerId, 'object_suffix');
   
   // Add a message to a pass object
   $demo->addObjectMessage($issuerId, 'object_suffix', 'header', 'body');
   
   // Expire a pass object
   $demo->expireObject($issuerId, 'object_suffix');
   
   // Generate an Add to Google Wallet link that creates a new pass class and object
   $demo->createJWTNewObjects($issuerId, 'class_suffix', 'object_suffix');
   
   // Generate an Add to Google Wallet link that references existing pass object(s)
   $demo->createJWTExistingObjects($issuerId);
   
   // Create pass objects in batch
   $demo->batchCreateObjects($issuerId, 'class_suffix');
