Introduction
When manual creation does not scale, an API automates QR for invoices, tickets, or product labels.
This guide gives a practical frame for QR code API integration: what to do, what to avoid, and how to measure. For developer docs, review the api-docs page.
Practical Checklist
Successful QR ops = design + content + placement + measurement. Neglect one link and the chain weakens.
- Keep destinations secure and mobile-friendly
- Apply brand style without excess
- Multi-device test before print
- Separate URLs / UTMs for campaigns
Common Mistakes
Low contrast, undersized print, covering finder patterns with logos, HTTP or broken links, and missing CTA copy are the most common mistakes.
QR strategy starts with the destination experience—before the generator.
