Taking a card is the easy part. We build gateway integrations that survive declines, dropped connections, duplicate clicks and refunds — so your orders are always right.
Tokenised, minimal PCI scope
SCA-compliant authentication
Order statuses stay accurate
OCMOD / VQMOD, no core edits
It's finished when it survives everything that goes wrong afterwards. Most integrations are tested on the happy path only — here's everything we check before calling one live.
Why this matters: almost every payment problem merchants bring to us is an edge case nobody tested — an order marked unpaid after the money arrived, a customer charged twice, a refund that never reached the gateway. The first successful transaction proves very little on its own.
Most stores need one of these. We'll tell you honestly which one your situation calls for.
Your provider is already one of the 32+ gateways we build and maintain. Install, configure, start accepting payments.
A regional bank, a niche processor, or your own in-house payment system. If it has documentation, we can build it.
The safest integration is one where sensitive data never reaches your server in the first place. That's how we build every gateway.
Card data goes straight to the provider. Your server only ever sees a token.
Hosted fields and redirect flows keep your compliance burden minimal.
Strong authentication implemented wherever the provider supports it.
Webhook signatures checked, so nobody can fake a paid order.
If any of these happen on your store, the integration — not the payment provider — is usually the cause.
Money reached the gateway but the order never updated. Almost always a broken or unverified callback.
A refreshed page or double-clicked button creating two transactions for one order.
Pending orders that never resolve either way, quietly piling up in your admin.
Your team logging into the gateway dashboard separately because OpenCart can't issue refunds.
Payment pages that work on desktop but fail, clip or redirect badly on phones.
The original developer is gone and no one knows how the integration actually works.
We repair inherited and third-party integrations as often as we build new ones.
