Troubleshooting

Common checks

Start with these checks when a modal does not open or a post-payment redirect is not happening.

• Confirm the modal script is loaded before calling window.makepay.showPayment.
• Make sure the payment UID is active and the hosted page still resolves.
• Listen for makepay.payment.redirect_requested if the host page should navigate after completion.
• Use data-makepay-payment-link only on clickable elements.

Escalation details

When escalating an issue, include the payment UID, the merchant page URL, the browser console output, and the event payload received from the embedded checkout.
