Automating Monobank payment reconciliation with n8n

For most Ukrainian online businesses, a familiar bottleneck appears the moment sales scale: someone has to open the Monobank statement, find each incoming transfer, match it to an order, and mark that order as paid. At ten orders a day it is an annoyance. At two hundred it becomes a daily job — and every manual match is a chance to confirm the wrong order, miss a payment, or ship goods that were never paid for.

The cost is rarely just time. Reconciliation lag delays fulfilment, frustrates customers waiting on confirmation, and leaves your accounting one step behind reality. When the person who "knows the spreadsheet" is on holiday, the whole process stalls.

The automation: Monobank, n8n, and your database

We replace the manual loop with an n8n workflow that watches Monobank, matches each payment to an order, and updates your store or accounting system without anyone touching a statement. The Monobank API exposes incoming transactions and supports webhooks, which makes it a clean fit for event-driven automation. n8n sits in the middle as the orchestration layer — receiving the event, applying your matching rules, and writing the result back to Laravel, WordPress (WooCommerce), or OpenCart.

Because the logic lives in one visual workflow rather than scattered across code and cron jobs, your team can see exactly how a payment becomes a confirmed order — and adjust the rules without a redeploy.

How we build it

1. Connect Monobank. We register a webhook on your Monobank account so every incoming transaction is pushed to a dedicated n8n endpoint in real time. No polling, no missed transfers.
2. Normalise the payload. An n8n Function node extracts the amount, timestamp, and payment reference (the order ID encoded in the transfer comment or generated at checkout).
3. Match to an order. n8n queries your database — via the Laravel/OpenCart API or a direct connection — to find the pending order with the matching reference and amount. Exact-amount and reference checks guard against false positives.
4. Update and confirm. On a match, the workflow flips the order status to "paid", writes the transaction ID for your audit trail, and triggers the next step — invoice generation, a Nova Poshta shipping label, or a customer notification.
5. Handle exceptions. Unmatched or partial payments route to a separate branch that alerts your team in Telegram or email, so edge cases get human attention instead of silently failing.

The result is reconciliation that runs in seconds, around the clock, with a complete log of every decision. Your accounting reflects reality, fulfilment starts the instant payment clears, and the spreadsheet ritual disappears. For a typical store, this removes hours of repetitive checking each week and closes the gap where revenue used to leak through missed or misapplied payments.

The same pattern extends naturally to LiqPay, Fondy, and direct card acquiring — one orchestration layer, many payment sources, consistent rules.
