One link
<a href="addpkpass://yourdomain.com/passes/ticket-123.pkpass">: WebViewGold turns it back into an https:// URL and opens it in an in-app browser tab, which recognizes the pass and shows the native Add to Apple Wallet preview.
How Add to Apple Wallet works in the app
You create and sign the pass
A .pkpass file is a signed bundle (pass.json, images, a manifest and a signature) made with your own Pass Type ID certificate from your Apple Developer account. Generate it on your server or with a pass service; WebViewGold hands it to Wallet.
Serve it correctly
HTTPS, the MIME type application/vnd.apple.pkpass and a valid signature. If any of the three is off, iOS cannot show the preview and the user sees an error instead.
Android: Google Wallet
Since 2024 Google Wallet can import many .pkpass files, but support varies by device and pass, and the addpkpass:// scheme is iOS-only. The dependable Android route is a Google Wallet pass created with the Google Wallet API and the official Add to Google Wallet button, which links to a save URL on pay.google.com that your server signs.

Prompt for ChatGPT or Codex
Prompt for Codex: Add Apple Wallet passes for event tickets and open a pull request. Create a server-side module that builds an eventTicket pass (event name, date, venue, seat, QR barcode with the ticket code, relevantDate, serialNumber = ticket id) and signs it with the Pass Type ID certificate, key and WWDR certificate from environment variables. Add an endpoint that returns a signed download URL, valid for ten minutes, to the ticket owner, and a download route that serves the file with Content-Type application/vnd.apple.pkpass. On the ticket page, render Apple's Add to Apple Wallet badge: when navigator.userAgent contains my custom WebViewGold token and the device is an iPhone or iPad, link to the download URL with https:// replaced by addpkpass://; in Safari use the https URL; on Android show a Download ticket PDF button. Add tests for token expiry and the pass contents, and document the pass rules in AGENTS.md.
My iOS WebView is finally approved. Thanks!!
Passes that fit vibe-coded apps
Apple Wallet has five pass styles: event ticket, store card, coupon, boarding pass and generic. The ones that come up most:
Event tickets
Workshops, meetups, concerts, classes. A QR code with the ticket ID, date and venue, and a relevant date so the pass appears on the lock screen before the event.
Loyalty and stamp cards
Cafes, salons, gyms. A store card with the member number as a barcode and a points balance that you can update later.
Coupons and offers
A discount code that is scanned at the counter or shown at checkout, with an expiry date users can see.
Membership and access
Club memberships, coworking access, VIP or season passes: identification is one of the uses Apple names explicitly.

A day for the first pass type; certificates take the longest.
Create a Pass Type ID and certificate
In your Apple Developer account under Certificates, Identifiers and Profiles, register a Pass Type ID (for example pass.com.yourcompany.tickets), create its certificate and download Apple's WWDR intermediate certificate. Both go to your server, never into the client.
Generate passes on your server
A server function in Your own API or serverless functions builds pass.json (serial number, barcode with the ticket code, relevant date or location) and signs it, for example with passkit-generator on Node or through a hosted pass API. Store the serial number with the order.
Protect the download with a token
The in-app browser tab may not share the web view's login cookies, so give the pass URL a signed, short-lived token instead of relying on the login session.
Add the button
Use Apple's official Add to Apple Wallet badge. Inside the iOS app, link to the pass with
addpkpass://; in Safari, the plain https link works natively; on Android show the Google Wallet button or a PDF ticket.Keep passes current (optional)
Add
webServiceURLandauthenticationTokento pass.json and implement Apple's pass web service; when a gate, seat or points balance changes, you notify the device via APNs and Wallet downloads the new version.Test on a real iPhone
Add a pass, open it from the lock screen, try an expired token and a voided ticket. Check that the barcode scans with the reader you actually use at the door.
One helper for every platform
Your server returns both URLs; the page picks the right one. YourAppToken is the custom user agent from Config.swift / Config.java.
javascript
var ua = navigator.userAgent;
var inApp = ua.indexOf("YourAppToken") !== -1;
var isIOS = /iPhone|iPad|iPod/.test(ua);
var isAndroid = /Android/.test(ua);
// pass = {
// pkpassUrl: "https://yourdomain.com/passes/T-1042.pkpass?t=SIGNED_TOKEN",
// googleSaveUrl: "https://pay.google.com/gp/v/save/SIGNED_JWT", // created by your server
// pdfUrl: "https://yourdomain.com/tickets/T-1042.pdf"
// }
function walletLink(pass) {
if (isIOS && inApp) return pass.pkpassUrl.replace(/^https:\/\//, "addpkpass://");
if (isIOS) return pass.pkpassUrl; // Safari opens .pkpass natively
if (isAndroid && pass.googleSaveUrl) return pass.googleSaveUrl;
return pass.pdfUrl; // desktop and fallback
}
document.getElementById("add-to-wallet").href = walletLink(window.currentPass);Android and Google Wallet
WebViewGold has no dedicated Google Wallet API, and the addpkpass:// scheme is iOS-only. The web route works well:
- Create an issuer account in the Google Pay and Wallet Console, define a pass class (event ticket, loyalty, offer or generic) and let your server sign a JWT with a service account. The result is a save link on pay.google.com.
- Open that link outside the web view, where the user is signed in to Google: add pay.google.com to
BROWSER_BLACKLISTin Config.java, or prefix the link withnewtab:and setSPECIAL_LINK_HANDLING_OPTIONSto 2 (URL handling docs). - Use Google's official Add to Google Wallet button artwork and follow its brand guidelines, just as you use Apple's badge on iOS.
- Recent Google Wallet versions can also import .pkpass files, but treat that as a bonus you test on your target devices, not as the plan: inside the app there is no Wallet handling for .pkpass links on Android.
- Always keep a fallback: a PDF ticket or the QR code on screen works on every device.
Frequently asked questions
Does WebViewGold create the Wallet pass for me?
No. WebViewGold delivers a pass to Apple Wallet. Creating and signing the .pkpass file happens on your server or in a pass service, with your own Pass Type ID certificate from the Apple Developer Program.
Does Add to Apple Wallet work on Android?
Apple Wallet exists only on Apple devices. Google Wallet can import many .pkpass files on recent Android phones, but support varies, so the dependable route is a Google Wallet pass created through the Google Wallet API, with its save link opened outside the web view (BROWSER_BLACKLIST in Config.java) where the user is signed in to Google. WebViewGold has no dedicated Google Wallet API.
Can I update a pass after the user added it?
Yes, with Apple's pass web service: include webServiceURL and authenticationToken in pass.json and Wallet registers the device with your server. When the gate, seat or balance changes, you send a push through APNs and Wallet fetches the new version.
Why does the pass open in an in-app browser tab?
That tab recognizes the .pkpass content type and shows the native Add to Apple Wallet preview. It may not share cookies with the main web view, so the pass URL must work without the app's login session, for example with a signed, expiring token.
Can users add passes from the website too?
Yes. Safari on iPhone and Mac opens .pkpass links natively, so the same https URL works on the web; only the app uses the addpkpass:// prefix.
