An n8n community package for Lago billing. Manage customers and subscriptions, send usage events, work with invoices and wallets, and receive signed billing webhooks.
Usage events use a transaction ID for Lago deduplication. The node’s default combines the n8n execution ID and item index. Reusing the same ID can protect retries within that execution; a new execution produces a different default. Supply a stable ID from the original business event when you need deduplication across replays.
The trigger verifies JWT or HMAC signatures. Optional duplicate filtering remembers the last 200 delivery keys in workflow static data when a delivery key is present. It is a bounded filter, not a guarantee of exactly-once processing.
Some actions depend on Lago licensing. Credit-note creation and estimation require premium features. Automatic wallet top-up configuration is not exposed. Check the operation and the Lago edition before designing a workflow around it.

This workflow listens to Lago payment webhooks, retries failed invoice collections up to three times, stores a durable dunning state in an n8n Data Table, and emails billing when a retry is requested, customer action is required, or a payment is recovered.
This workflow receives AI token usage via a webhook, estimates the prepaid cost and projected credit balance in Lago, records the usage as a Lago event, and returns a receipt that warns when credits are at or below a configurable threshold.
