n8n Workflow: Sell Ebooks with Google Gemini, Drive & Email

Turn a product idea into a sellable e-book—automatically

This n8n workflow takes a topic from your webhook, uses Google Gemini to research and write a complete e-book, converts it to PDF via PDFShift, uploads it to Google Drive, publishes the product through Lynk.id, generates social promo copy, and delivers the download link to buyers by email after successful payment.

What this workflow does

• Kickoff with a webhook: Receives a POST request with a product topic to start the e-book creation process.
• Generate the e-book plan: Uses Google Gemini to produce a structured JSON output including the e-book title, target audience, price, and chapter outline.
• Write the full manuscript: Uses Google Gemini again to generate the e-book in Markdown based on the outline.
• Create a PDF and host it: Sends the Markdown to PDFShift to generate a PDF, then uploads the PDF to Google Drive.
• Publish the product: Uses Google Gemini to generate an AIDA-style HTML sales page, then creates the product in Lynk.id with the price, description, and Google Drive file link.
• Generate promotion: Uses Google Gemini to create three Threads/Instagram promo posts including a CTA link provided in the incoming data.
• Deliver after payment success: Waits for a separate payment-success webhook, then emails the buyer the download link and sends a follow-up request for a testimonial three days later.

Use cases

• Launch niche e-books on-demand for SaaS operators without manual writing, formatting, or hosting.
• Automate a mini “content-to-commerce” pipeline: topic → PDF → sales page → Lynk.id product → email delivery.
• Reduce time spent preparing digital products by combining Gemini research, PDF generation, and Google Drive publishing.
