🔐 PIX QR Code Generator for Any Bank and Key – Powered by n8n

Easily generate PIX QR Codes with this ready-to-use n8n workflow, supporting any valid PIX key (CPF, CNPJ, phone, email, or random key) and following the official BACEN standard — the Central Bank of Brazil's regulation.

Whether you want to automate payments in chatbots, CRM systems, e-commerce checkouts, or custom apps, this solution provides fast, secure, and fully compliant QR Code generation.

💡 What is PIX?

PIX is a real-time payment system developed by the Central Bank of Brazil (BACEN).
It allows instant transfers between banks, available 24/7, without fees for individuals.
Businesses widely use PIX for quick, easy, and reliable payments — making QR Codes an essential tool for sales, subscriptions, and customer service.

⚙️ What this Workflow Does

  • Creates a fully compliant PIX payment code with automatic checksum (CRC)
  • Generates a dynamic QR Code that customers can scan with any banking app
  • Returns:
    • The full PIX EMV payment code (ready for integration)
    • A public URL linking to the QR Code image
    • Clean payment metadata for frontend or messaging bots

All generated dynamically from the user's input: key, amount, receiver name, city, and payment description.

🧠 How it Works

  1. The user provides basic payment information: key, amount, name, city, and description.
  2. The workflow assembles a PIX payload following BACEN's EMV QR standards.
  3. It automatically generates and attaches the CRC (checksum) for validation.
  4. A QR Code is created based on the complete PIX code.
  5. The output returns both the PIX code and a QR Code image URL, ready to use anywhere.

Each component works seamlessly to deliver a ready-to-scan QR Code for instant payments.

🛠️ How to Set Up

  1. Deploy the workflow on your n8n Cloud or self-hosted instance.
  2. Configure the input variables manually or through an API/Webhook:
    • pixKey: Your PIX key (CPF, CNPJ, email, phone, or random)
    • receiverName: Name of the individual or company receiving the payment
    • city: City name associated with the receiver
    • amount: Payment value (in BRL, ex: 79.90)
    • description: Short description for the transaction (optional)
  3. Trigger the workflow:
    • Manually (for testing)
    • Via webhook/API (ideal for integrations with chatbots, e-commerce, CRM)
  4. Customize the flow (optional):
    • Set default values if user inputs are missing
    • Adjust QR Code size or styling (inside the QR Code generator node)
    • Connect to database/storage if you want to save issued PIX transactions

🎯 Who is This For?

  • E-commerce stores needing instant payment links
  • Chatbots or WhatsApp bots offering product sales or bookings
  • CRM systems wanting to automate billing processes
  • Subscription platforms requiring fast payment confirmation
  • Any business wanting to accept payments faster and smarter

✅ Requirements

  • Active n8n Cloud or self-hosted instance
  • A valid PIX key (CPF, CNPJ, email, phone, or random key)
  • Basic payment information: amount, city, receiver name, description
  • No external paid APIs needed — fully open and server-side
