The files in this directory each implement a demo class for a specific Google Wallet pass type. Each class implements methods for performing tasks such as creating a pass class, updating issuer permissions, and more.

• Node.js 18.x
• NPM 8.x
• Follow the steps outlined in the Google Wallet prerequisites to create the Google Wallet issuer account and Google Cloud service account

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.

1. Use npm to install the dependencies in the package.json

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

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

   // Import the demo class
   const { DemoEventTicket } = require('./demo-eventticket');
   
   // Create a demo class instance
   // Creates the authenticated HTTP client
   let demo = new DemoEventTicket();
   
   // Create a pass class
   demo.createClass('issuer_id', 'class_suffix');
   
   // Update a pass class
   demo.updateClass('issuer_id', 'class_suffix');
   
   // Patch a pass class
   demo.patchClass('issuer_id', 'class_suffix');
   
   // Add a message to a pass class
   demo.addClassMessage('issuer_id', 'class_suffix', 'header', 'body');
   
   // Create a pass object
   demo.createObject('issuer_id', 'class_suffix', 'object_suffix');
   
   // Update a pass object
   demo.updateObject('issuer_id', 'object_suffix');
   
   // Patch a pass object
   demo.patchObject('issuer_id', 'object_suffix');
   
   // Add a message to a pass object
   demo.addObjectMessage('issuer_id', 'object_suffix', 'header', 'body');
   
   // Expire a pass object
   demo.expireObject('issuer_id', 'object_suffix');
   
   // Generate an Add to Google Wallet link that creates a new pass class and object
   demo.createJwtNewObjects('issuer_id', 'class_suffix', 'object_suffix');
   
   // Generate an Add to Google Wallet link that references existing pass object(s)
   demo.createJwtExistingObjects('issuer_id');
   
   // Create pass objects in batch
   demo.batchCreateObjects('issuer_id', 'class_suffix');
