Apple Wallet (PassKit) enables users to store event tickets, passes, and boarding passes directly on their iPhones for instant access. In this guide, we’ll cover how to integrate Apple Wallet into your Node.js application using .pkpass files and the passkit-generator package.
We’ll go step by step: from setting up certificates in Apple Developer Portal to generating passes and delivering them to users.
An Apple Wallet pass (.pkpass) is simply a zipped bundle containing:
pass.json — metadata (event info, barcodes, colors)manifest.json — list of files with hashessignature — signed with your Apple certificateApple PassKit Package Format Reference

openssl req -new -newkey rsa:2048 -nodes -keyout pass.key -out pass.csr.cer).p12 Format.cer to install into Keychain Access.p12.pem format:openssl x509 -in AppleWWDRCAG3.cer -inform DER -out wwdr.pem -outform PEMAt this point, you have:
pass.p12 → Pass Type Certificate (with password)wwdr.pem → Apple WWDR certificatepass.key → private keyThese will be used to sign your passes in Node.js.

We’ll use passkit-generator.
npm install passkit-generator
import {
PKPass
} from "passkit-generator";
import fs from "fs";
// Load certificates
const cert = fs.readFileSync("./certs/pass.p12");
const wwdr = fs.readFileSync("./certs/wwdr.pem");
const password = "your-cert-password";
// Create pass
const pass = new PKPass({
model: "./eventPass", // folder containing pass.json + images
certificates: {
wwdr,
signerCert: cert,
signerKeyPassphrase: password,
},
}, {
serialNumber: "TICKET12345",
description: "Concert Ticket",
});
// Add details
pass.fields.primaryFields.add("event", "Concert Night", "Gate Opens 7 PM");
pass.fields.secondaryFields.add("venue", "Sunshine Arena");
// Add QR code
pass.setBarcodes({
message: "TICKET12345",
format: "PKBarcodeFormatQR",
});
// Save pass
fs.writeFileSync("event-ticket.pkpass", pass.getAsBuffer());

By creating a Pass Type ID and certificates in the Apple Developer portal, then generating .pkpass files in Node.js, you can integrate Apple Wallet support into your ticketing system and deliver a seamless user experience.
