How to Sync Stripe Payments to QuickBooks Automatically with n8n

Add a Webhook node in n8n and copy its production URL. In the Stripe Dashboard, go to Developers > Webhooks and add an endpoint using that URL, subscribed to the charge.succeeded (or invoice.payment_succeeded, if you invoice clients through Stripe) event.

Stripe signs every webhook payload. Add a Code node right after the trigger that verifies the signature using your Stripe webhook signing secret, and stops the workflow if it doesn't match. This is a security step, without it, anyone who finds your webhook URL could send fake "payment succeeded" events.

Pull the customer email, amount (Stripe sends this in cents, divide by 100 before using it anywhere), currency, and charge ID out of the payload. The charge ID is important, you'll use it in a later step to avoid recording the same payment twice.

Add a QuickBooks Online node set to Search Customer by email. If no match is found, branch to a fallback (create the customer, or route to a Slack channel for manual review, depending on how strict you want this to be).

Add a QuickBooks node set to Create Payment (if this Stripe charge pays down an existing invoice) or Create Sales Receipt (if there's no invoice on file, common for one-off or self-serve purchases). Map the amount, customer, and date from the Stripe payload.

Add a note or custom field on the QuickBooks record storing the Stripe charge ID. Before creating a new payment, add a check earlier in the workflow that searches for this ID first, Stripe retries webhook delivery on failures, so without this check, a single payment can get recorded twice.
