Error Handling

​
Invalid Size Parameter

If the size parameter is outside the allowed range (300-600), the API will return an error: 
{
  "error": "Invalid size parameter",
  "message": "Size must be between 300 and 600 pixels for printable format"
}

​
QR Code Not Found

If the QR code ID doesn’t exist: 
{
  "error": "Not found",
  "message": "QR code not found"
}

​
Missing Required Parameters

If for_print is not set to “true”: 
{
  "error": "Invalid parameter",
  "message": "for_print must be set to true for printable format"
}

​
Best Practices

  • ✅ Use for_print=true only when generating files for offset or large-format printing.
  • ✅ Maintain high resolution (≥400px) for print clarity.
  • ⚠️ Avoid applying design layers or colors — print mode always outputs black-only QR codes.
  • 💡 Include the name parameter to generate descriptive filenames for easy organization (e.g., event-qr-print.pdf).
  • 🔒 Store API keys securely and restrict access to authorized systems only.

​
When to Use: Printable vs Standard Download

  • Use Standard for digital applications where colors, frames, or logos are needed.
  • Use Printable when you need a print-ready, high-contrast, black-only QR code for professional printing.
