Every program has a pass template — the design and content that all of its passes inherit: colors, logo, images, text fields, and barcodes. The template editor lets you fine-tune it with a live preview.
To open the editor, go to your program and click Edit template in the Wallet card template section.
Before diving into the editor, it pays to understand what you’re editing — see the anatomy of a pass for how the areas of a pass fit together. How the editor works
The left side shows a live preview of your pass — front and back. The right side holds the controls, organized in tabs:
| Tab | What you edit | Details |
|---|
| Settings | Organization name, description, and pass style | The pass style sets the overall layout — see anatomy |
| Design | Colors, visual options, and images | See images for every slot and its dimensions |
| Content | Logo text, the pass fields, and dates | See fields and dynamic content |
| Advanced | Barcodes, locations, sharing, and pass actions | See barcodes and NFC |
| Localization | Translations for each language you support | Organization name, description, logo text, fields, and barcode alt text per language |
| Semantic | Structured data the wallet can use | Loyalty, event, or transit details, depending on the pass style |
Saving changes
- Make your edits — the preview updates as you go. A colored dot next to the template name warns you about validation issues.
- Click Save. The save dialog summarizes your changes and lists any errors (which block saving) or warnings (which don’t).
- Click Confirm Save.
Saving applies your changes to all existing passes immediately — every customer’s pass updates to the new design, not just passes issued from now on.
From preview to wallet
The preview is faithful: what you see in the editor is what customers get on their phone. The same template shown in the editor screenshot above renders like this in Apple Wallet:
Good to know
- The template belongs to its program — you can’t move it to another program from the portal.
- The preview shows the Apple Wallet layout. Google Wallet renders the same template differently — see Apple Wallet vs Google Wallet.
- Stell creates an initial working template for your program, so you’re always improving a working pass rather than starting from a blank canvas.
