Deliver workflows after Stripe checkout with Gmail and Google Sheets

Quick overview

This workflow listens for completed Stripe Checkout sessions, validates payment status, fetches the purchased workflow from your n8n instance, exports it as a JSON file, emails it to the buyer via Gmail, and logs the sale details to Google Sheets.

How it works

1. Triggers when Stripe sends a checkout.session.completed event for a Checkout session.
2. Normalizes key fields from the Stripe event (buyer email, payment status, amount, session ID, and the workflow ID from client_reference_id).
3. Verifies the event is a completed checkout session and the payment status is not unpaid.
4. Retrieves the purchased workflow from the n8n API using the workflow ID passed through Stripe.
5. Appends a sales record to Google Sheets with the timestamp, buyer email, amount, session ID, and workflow details.
6. Exports the fetched workflow to a formatted JSON file and sends it to the buyer as a Gmail attachment with import instructions.

Setup

1. Add credentials for Stripe, n8n API, Gmail OAuth2, and Google Sheets OAuth2 used by the workflow.
2. Create or select a Google Sheets spreadsheet and a Sales sheet tab, and ensure the column headers match the fields being appended (Timestamp, Workflow ID, Workflow Name, Buyer Email, Amount USD, Session ID).
3. Configure your Stripe Checkout/Payment Link to pass the n8n workflow ID in client_reference_id so the workflow can fetch and deliver the correct workflow JSON.
