Stripe Invoice Generation and Delivery
On successful payment, it validates the amount, generates a Net 30 invoice PDF, emails it to the customer, saves it to Drive.
What it does
Receive a finalized Net 30 invoice PDF immediately after your payment succeeds, delivered directly to the customer's email and saved securely in your Google Drive. This process validates the transaction amount automatically and notifies you via WhatsApp once everything is complete.
Step by step
- Configure a Stripe webhook listener to trigger on the invoice.payment_succeeded event.
- Use the Stripe SDK to fetch customer details and line items from the successful payment object.
- Format the invoice data into an HTML template with Net 30 terms before rendering it as PDF.
- Upload the generated PDF file to Google Drive using the authenticated service account credentials.
Where the LLM does the work
- Generate professional email body copy that references the specific invoice amount and due date.
- Create a concise WhatsApp alert message for admins that highlights any validation failures or high-value payments.
- Design the HTML/CSS structure of the PDF template to ensure it renders correctly across different email clients.
Watch out for
Gmail API quotas may restrict bulk sending so add a small delay between emails if processing high volumes.
PDF rendering libraries often struggle with complex CSS so test the template layout with edge case currency formats early.
WhatsApp messages via Rapiwa require valid phone numbers in E.164 format so validate and clean customer data before sending.

The agent brief
Everything your agent needs, including the gotchas. Copy it and go.
You are helping me build the following AI agent workflow. ## Goal Stripe Invoice Generation and Delivery: On successful payment, it validates the amount, generates a Net 30 invoice PDF, emails it to the customer, saves it to Drive. ## Specification - What it does: Receive a finalized Net 30 invoice PDF immediately after your payment succeeds, delivered directly to the customer's email and saved securely in your Google Drive. This process validates the transaction amount automatically and notifies you via WhatsApp once everything is complete. - Trigger: Triggered by an event (Event · on successful Stripe payment) - Autonomy: Fully hands-off - Expected setup effort: about an afternoon - Tools/services involved: - Stripe: Trigger and invoice creation - Gmail: Sending invoices to customers - Google Drive: Storing invoice PDFs - Rapiwa: Sending admin WhatsApp notifications ## Known pitfalls, handle each one explicitly in your implementation 1. Gmail API quotas may restrict bulk sending so add a small delay between emails if processing high volumes. 2. PDF rendering libraries often struggle with complex CSS so test the template layout with edge case currency formats early. 3. WhatsApp messages via Rapiwa require valid phone numbers in E.164 format so validate and clean customer data before sending. ## Reference implementation https://n8n.io/workflows/16480 (workflow template) Fetch and inspect this before building. If it matches my stack, adapt it; if not, rebuild the pattern with my tools. ## Process requirements 1. Before building: ask me which of the listed tools I actually use and what my platform is (n8n / Make / code / other). Do not assume. 2. Adapt the pattern to my answers; do not force the reference stack. 3. Address every pitfall above; tell me how you handled each. 4. Provide a test plan I can run before letting this touch real data. 5. Ask before any step that sends messages, modifies data, or spends money.

Frequently asked questions
Can I use a different Payments than Stripe?
Yes. Stripe is only the example payments in this recipe. The same flow works with PayPal and Razorpay API. Swap the payments connection and keep the rest of the setup as written.
