Automated Monobank payment reconciliation with n8n

Most online businesses still reconcile payments by hand. A finance manager opens the Monobank statement, scrolls through incoming transfers, and ticks them off against orders in the CRM or accounting system. It works — until volume grows. At a few hundred transactions a day, manual matching becomes a daily bottleneck: orders ship late because payment confirmation lags, partial and duplicate payments slip through, and month-end close turns into detective work.

The business cost of manual reconciliation

Every unmatched payment is operational drag. Support teams field "I already paid" tickets, accountants reconcile twice — once to ship, once to close the books — and cash position stays unclear until someone finishes the spreadsheet. The work is repetitive, rules-based, and entirely automatable. That makes it the ideal first candidate for a reconciliation workflow.

The automation: n8n as the matching engine

n8n is a self-hostable workflow automation platform that connects APIs without custom glue code for every integration. For reconciliation it acts as the engine that listens for new Monobank transactions, finds the matching order, and updates your system of record — Laravel, OpenCart, or a CRM — the moment money lands. Self-hosting matters here: financial data stays on your infrastructure, not a third-party cloud, which keeps you aligned with your data-protection obligations.

Concrete steps to build it

1. Connect the Monobank API. Register a token through Monobank's corporate API and configure the webhook so each incoming transaction triggers your n8n workflow instantly — no polling, no delay.
2. Normalize the payload. Use a Function node to extract amount, timestamp, counterparty, and the payment reference or comment that carries your order identifier.
3. Match against orders. Query your Laravel or OpenCart database (HTTP Request or a database node) for an open order matching the amount and reference. Apply a tolerance rule for rounding and fees.
4. Update the system of record. On a confident match, mark the order paid, write the bank reference to the order, and fire downstream actions — invoice, fulfilment trigger, customer notification.
5. Route the exceptions. Unmatched, partial, or duplicate payments go to a dedicated queue — a Telegram alert or a row in a review sheet — so a human handles only the genuine edge cases instead of every transaction.

The result

Reconciliation drops from a daily manual chore to a background process that runs in seconds per transaction. Orders ship as soon as payment clears, cash position is accurate in real time, and your finance team reviews exceptions only — typically a small fraction of total volume. The rules-based 95% runs itself.
