Choose and test cross-border payments for your storefront

Payment setup has to work for buyers and for the merchant's settlement requirements. More gateways do not automatically lift conversion. For the first market, get one primary method working reliably before adding another.

Questions to answer before connecting a gateway

• Do target buyers use this method?
• Does the merchant entity meet the provider's onboarding requirements?
• Who owns refunds, disputes, and reconciliation?
• Which costs come from the provider and which come from the commerce platform?

Test the callback flow

Use a sandbox or low-value live order to test success, cancellation, failure, and refunds. The order status in the platform should match the payment provider after each test. Keys, private certificates, and webhook settings belong in the configured environment, not in public documentation.

After release, watch the failures

Watch failure rates, payment-method mix, and order-state exceptions. When a payment fails, keep the order ID, provider reference, and timestamp. Those details make a support case much easier to trace.
