Monobank Acquiring in Laravel: a practical integration guide

Ukrainian shoppers increasingly choose Monobank for everyday payments. Adding Monobank Acquiring to your Laravel store shortens checkout from four steps to two — and that friction reduction translates directly into fewer abandoned carts.

What Monobank Acquiring gives you

Monobank's REST API lets you generate a hosted payment page, receive webhook confirmations, and query invoice status without handling raw card data. Your Laravel application stays PCI-scope-light while the customer gets a familiar, trusted checkout experience.

The integration flow

Three endpoints cover 90% of use cases:

• POST /api/merchant/invoice/create — create an invoice with amount (in kopecks), redirect URLs, and optional cart metadata.
• POST /api/merchant/invoice/status — poll payment status when a webhook is delayed.
• DELETE /api/merchant/invoice/remove — cancel an unpaid invoice to release funds on hold.

Laravel implementation in four steps

1. Store credentials securely

Add your merchant token to .env and reference it via config('services.monobank.token'). Never hardcode API keys in source files.

2. Create an invoice service class

Wrap all Monobank API calls in a dedicated MonobankAcquiringService class. Use Laravel's Http facade with retry logic — Http::retry(3, 100)->post(...) — to handle transient network errors gracefully.

3. Verify webhook signatures

Monobank signs every callback with an RSA signature in the X-Sign header. Always verify this against the public key before processing. Forged callbacks are a real attack vector; skipping verification is not an option in production.

4. Process orders asynchronously

Dispatch a ProcessMonobankOrder job after signature verification. The webhook endpoint returns a 200 response immediately; fulfillment — inventory update, email notification, Nova Poshta TTN generation — runs in the background via Laravel Queue.

What this looks like in production

A typical Laravel + Monobank integration handles 500–2,000 daily transactions without additional infrastructure. Pair it with Laravel Horizon for queue monitoring and you have full visibility into payment throughput and job failures.

The business result

Monobank Acquiring cuts checkout steps, increases trust with Ukrainian shoppers, and keeps your reconciliation clean with structured webhook logging. Implementation takes 3–5 days on an existing Laravel codebase.
