This project is based on the Node.js examples from the Google Wallet repository, which I modified to suit my needs. You can find the original repository here: google-wallet/rest-samples.
In this article, I will walk you through the process of creating and updating passes for Google Wallet. I also cover the process for Apple Wallet here.
- 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.
