How to create an Apple Wallet pass with Grok

Grok can create an Apple Wallet pass from a sentence. Add WalletPassBuilder to Grok once as a connector, describe the card in a chat, and Grok hands back a link that adds it to Apple Wallet on an iPhone or Google Wallet on Android. The same connection lets Grok change the pass later, message everyone who saved it, and run a loyalty stamp card.

Last updated November 4, 2026. Facts about Apple Wallet and Google Wallet were checked against Apple’s and Google’s own documentation, linked in the sources.

The short answer

1. Go to grok.com/connectors, click New Connector, choose Custom and paste https://walletpassbuilder.com/api/mcp.
2. Sign in to WalletPassBuilder and approve the connection.
3. Describe the pass you want. Grok creates it and gives you its share link.

Nothing to install, no code, and no template to design first. You need a WalletPassBuilder account (new accounts get free pass credits to start) and a Grok account.

What Grok can do once connected

WalletPassBuilder’s MCP server gives Grok these actions. Grok picks the right one from what you ask; you never name them.

Six things to ask

One conversation covers the whole job: create the pass, reward customers, send updates and check results, in plain words.

Check what's live

Here's a summary of your tickets and credits.

1. Connect WalletPassBuilder to Grok

1. Open grok.com/connectors and click New Connector.
2. Choose Custom. If it asks for a name, use WalletPassBuilder. For the server URL, paste:https://walletpassbuilder.com/api/mcpCopy
3. Grok opens WalletPassBuilder’s sign-in in a pop-up (allow pop-ups from grok.com if your browser blocks it). Sign in and click Approve.
4. Start a new chat and ask for a pass.

On Grok Business or Enterprise

An admin provisions the connector for the team first, in the xAI cloud console. Each person then connects it and signs in with their own WalletPassBuilder account.

Grok doesn’t pick up the message you sent before connecting, so send a new one once it’s connected.

2. Create your first pass

With the connector added, describe the card:

Grok turns that into a pass: the business name, a title, up to three fields on the front, the QR code and anything you want on the back. With no logo image, it uses a simple icon in the card’s color, and you can send a logo URL instead. It replies with the share link.

For a whole list of people, paste the list and ask for “a card for each person”. Grok makes one pass with a card per person, each with its own link, up to 500 at a time.

3. Put it on a phone

Send the share link by email, text or chat. The page it opens checks the device:

• On an iPhone, an Add to Apple Wallet button adds the pass.
• On Android, an Add to Google Wallet button adds the same card.
• On a computer, the Apple Wallet button shows a QR code to scan with an iPhone.

More on that step in how to add a pass to Apple Wallet or Google Wallet.

4. Change it later

A saved pass isn’t a snapshot. Ask Grok to change it, in the same chat or a new one: “Move Priya to Premium and set her renewal to March 2027.” Only what you name changes, and the card updates on every phone it’s saved on. Updates don’t use credits.

5. Run a loyalty program

“Create a stamp card for Bean There Café: 8 stamps, a free coffee as the reward, a cream background.” Grok creates the program and gives you its sign-up link. Put that on a QR sign at the counter and every customer who scans it gets their own card.

Later, “Give Sam Lee a stamp” adds one to Sam’s card, and “Who joined this week?” lists your customers and their progress. For the counter itself, the dashboard’s staff scanner is quicker. See loyalty cards for small businesses for how to set up the program itself.

6. Send an offer to the lock screen

“Tell everyone with the Bean There card: double stamps all weekend.” Grok shows you the exact message and which pass it’s for, and sends it only after you say yes. It appears on the lock screen in Apple Wallet and on the card in Google Wallet. You can also schedule it: “Send it Saturday at 9am.”

Keep messages rare and useful. Our wallet pass notifications guide covers what works.

What Grok can’t do

• See or change your billing, API key, team or password.
• See your loyalty customers’ phone numbers.
• Keep access after you disconnect it: open API in the dashboard, then Connected apps, and click Disconnect.
