# About Wallet pass builders

The pass builder is where you design a Wallet pass: pick a layout, add your branding, fields, and a barcode, and check a live preview before you generate the pass. Apple Wallet and Google Wallet each have their own builder, because the two platforms support different layouts and fields.

<Aside type="note" title="Before you design a pass">
A developer connects the wallet platform to your application first. See [Getting started with Wallet passes](/product/messaging-channels/wallet-passes/).

## After you generate the pass

* **Send it to users:** share the install link or QR code. See [Share Wallet passes](/product/messaging-channels/wallet-passes/share-passes/).
* **Edit and track it:** change the pass, delete it, or find its holders. See [Manage Wallet passes](/product/messaging-channels/wallet-passes/manage-passes/).

<Aside type="tip">
To issue one pass design to many users and update shared fields on every issued pass at once, use [Wallet Pass Campaigns](/product/messaging-channels/wallet-passes/wallet-pass-campaigns/) instead of building each pass separately.
