You maintain one template per program, and Stell renders it for both wallets. Apple Wallet follows your template closely — it’s what the editor preview shows. Google Wallet uses a more standardized card layout, so the same template comes out simpler there. Knowing the differences saves surprises.

What carries over to Google Wallet

Primary, secondary, and auxiliary fieldsUp to 3 rows of 3 fields on the card front, in that priority order
Header and back fieldsIn the details section below the card, not on the front

What doesn’t carry over

  • Strip image — Google Wallet has no strip-image concept; the card relies on your background color and logo.
  • Pass style — Store Card, Coupon, and the other styles are Apple layouts. On Google, every program uses the standard card layout.
  • Background image and poster artwork — not used on the Google card.
  • Notification icon — Apple-specific.

What this means in practice

  • Don’t put critical information only in an image. A points balance baked into the strip image is invisible on Google Wallet — keep values in fields, which render on both.
  • Pick a background color that stands alone. On Apple the strip image dominates; on Google the background color is the design.
  • Mind the front-field budget. Google shows at most 3 rows × 3 fields on the front; anything beyond that moves to the details section. Your most important fields should be in the primary and secondary areas so they win the front-row spots on both wallets.
  • Test on both. After significant template changes, issue a test pass for each wallet type and look at them side by side.
The customer enrollment flow currently issues Apple Wallet passes only — Google Wallet passes are issued from the portal or via the API.
