Ukrainian e-commerce businesses often pay an extra 0.5–1.5% per transaction when routing payments through a third-party gateway middleware. Connecting Monobank's Acquiring API directly to your Laravel application removes that overhead and delivers real-time payment data straight to your system.
What direct integration delivers
Direct API access gives you:
- Instant webhook notifications when payment status changes
- Full control over the checkout UI and payment flow
- No third-party dashboard to reconcile end-of-day
- Lower transaction cost — fees go to the acquirer, not a middleware vendor
How the Laravel integration works
The integration consists of three focused components:
Invoice service
A dedicated service class calls POST /api/merchant/invoice/create, passing the order amount, currency, and a signed callback URL. Monobank returns a hosted payment link you display at checkout.
Webhook controller
Monobank POSTs a signed status update to your endpoint on every payment event. The controller validates the X-Sign header against your merchant token, then dispatches an OrderPaid or OrderFailed event to your Laravel queue.
Reconciliation command
A scheduled Artisan command polls GET /api/merchant/invoice/status for orders stuck in processing state longer than 15 minutes — a reliable fallback for missed webhooks.
Real result
A wholesale OpenCart store migrated from a third-party provider to direct Monobank integration. Per-transaction cost dropped by 1.4%. Daily reconciliation time fell from 90 minutes to under 8 minutes.
Stack requirements
PHP 8.1+, Laravel 10 or 11, Laravel Horizon for queue processing. Delivery: 3–5 working days including Monobank sandbox verification.
