What to Do When a Payment Method Is Unavailable

Identify whether the issue affects the shopper or the store

Note the device, checkout page, cart currency, and shipping region where the method is missing. Compare with a known supported checkout in a test environment. Check whether the method is enabled for the merchant and whether the extension or wallet has separate requirements for that storefront.

Verify that no payment is already in flight

Search the provider record for the original attempt and compare it with the store order. If there is an authorization, capture, or pending payment, follow the provider’s guidance before requesting another attempt. Give the customer an accurate status and use the normal support channel for updates.

Present only approved alternatives

• Show an available method supported for the same account, order, and sales channel.
• Explain any change to checkout or payment confirmation before sending the customer to the approved alternative.
• If no approved option is available, document the issue and escalate to the provider or checkout owner.
