Prepare Storefront Domains for Digital Wallet Checkout

Inventory the domains customers actually use

Record the final checkout host, alternate storefront hosts, and any subdomain that embeds or opens a payment page. Some wallet integrations require domain registration or validation. Ask who manages verification for the intended provider, account, and integration.

Test visibility independently of successful payment

A button can be absent because of the browser, device, account, or domain configuration. Test supported devices and the live-shaped URL, then separately test an approved sandbox payment. Check the regular card form on a device where the wallet is unavailable.

Keep domain changes in the release checklist

A staging domain working does not establish that a new production domain is registered. When changing hosts or checkout layouts, confirm which domain configuration is required and who maintains it. Ask whether an iframe or redirect changes the provider’s validation process.

Prove the customer path

• Wallet appears on the intended device and approved domain.
• The authorized wallet amount matches the order, tax, and shipping.
• Canceling the wallet returns the shopper to a usable card checkout.
