Monobank API integration for Laravel and OpenCart: faster payments, less overhead
Ukrainian e-commerce stores lose an average of 15–20% of conversions at the payment step — not because of pricing, but because of friction. Adding Monobank as a native payment option removes that friction. We integrate Monobank Acquiring directly into Laravel and OpenCart projects, cutting checkout time and reducing manual reconciliation by up to 80%.
Why Monobank, and why now
Monobank is Ukraine's most-used digital bank, with over 8 million active users. When your store accepts Monobank payments natively — not through a third-party aggregator — your customers pay in two taps. For merchants, that means:
- Instant payment confirmation via webhook callbacks
- Automated order status updates without operator intervention
- Full transaction history synced to your admin panel
How we integrate
For Laravel projects, we build a dedicated payment service class that wraps the Monobank Acquiring API. The flow:
- Generate an invoice via
POST /api/merchant/invoice/create - Redirect the customer to the Monobank payment page
- Receive a signed webhook callback upon payment
- Update order status and trigger downstream automations — CRM update, warehouse notification, email receipt
For OpenCart stores, we develop a custom payment extension that plugs into OpenCart's extension framework. No core modifications. No update conflicts.
What the integration delivers
On a mid-sized OpenCart store processing 1,000–5,000 orders per month, replacing a manual payment workflow with a Monobank API integration typically recovers 12+ operator hours per week. That's time your team spends on growth, not copy-pasting transaction IDs.
We also add webhook signature verification using HMAC-SHA512 to ensure every callback is authentic — no fraudulent order confirmations.
Technical requirements
- PHP 8.1+
- Laravel 10+ or OpenCart 3.x / 4.x
- SSL certificate (required by Monobank API)
- Monobank merchant account (setup takes under 24 hours)
Ready to reduce checkout friction?
We've implemented Monobank integrations for Ukrainian retailers across multiple verticals. If your store runs on Laravel, OpenCart, or WordPress, we can deliver a tested integration in 5–7 business days.
