Accept UAPAY payments in your OpenCart / ocStore 3.x shop without an intermediary Payment Hub. The extension integrates directly with the provider API and keeps the entire journey, from checkout to confirmation and refund, under control.
What your store gets
UAPAY with signed callbacks
HS256 JWT is validated before an order changes; a refund remains processing until its amount is confirmed by the provider.
Statuses and retries
Configure awaiting-payment, paid, failed and refunded statuses independently. New attempts preserve the previous payment history.
Refunds from the order
Full and partial refunds are tracked separately, while an unresolved operation is protected against an accidental second request.
Cron reconciliation
Scheduled checks can pick up delayed results and help finish processing when a callback is late.
Go-live checklist
Compatibility and package
OpenCart / ocStore 3.0.x · PHP 7.1+ · UAH · cURL, JSON, hash, NTP
Before going live
UAPAY must whitelist the production callback URL. Run sandbox payment and refund tests, enable PAYMENT_TRANSITION_FAILED and keep the server clock accurate. A merchant agreement and UAPAY account are required. Without merchant credentials the demo shows settings only; it cannot process real payments.
Compatibility and package
Included: OCMOD installer 1.0.2, documentation, status mapping, payment-attempt journal, refund workflow and reconciliation. Our installation, connection and test payment are free under the current promotion. Updates and support for 12 months.
