バッチ動的QR Code生成
Generating thousands of unique dynamic QR codes programmatically: CSV import, API batch endpoints, and template systems.
Batch Dynamic QR Code Generation
Generating hundreds or thousands of unique dynamic QR codes programmatically enables personalised marketing, serialised product authentication, and event ticketing at scale.
CSV Import
Most dynamic QR platforms support bulk creation via CSV upload:
name,destination_url,short_code
Product_001,https://example.com/verify/ABC123,p001
Product_002,https://example.com/verify/DEF456,p002
Each row creates a unique dynamic QR code with its own short URL, analytics, and editable destination.
API-Based Generation
For programmatic workflows, use the platform's REST API:
POST /api/v1/qrcodes
{
"destination": "https://example.com/product/12345",
"name": "Product 12345",
"folder": "Spring Campaign"
}
The API returns the short URL and QR code image (PNG, SVG, or both).
Template Systems
Templates define common settings applied to all batch-generated codes:
- Design template (colours, logo, frame)
- Error correction level
- Export format (PNG, SVG, PDF)
- Default analytics settings
Print Integration
For batch printing (product labels, direct mail, event tickets):
- Generate QR codes via API or CSV
- Download images in bulk (ZIP archive)
- Use variable data printing (VDP) to place unique QR codes on each printed piece
- Reference by filename or short code for print merge
Scale Considerations
| Volume | Approach | Typical Time |
|---|---|---|
| 10-100 | Manual or CSV import | Minutes |
| 100-1,000 | CSV import or API | 5-30 minutes |
| 1,000-10,000 | API with async processing | 30-120 minutes |
| 10,000+ | API with webhook callbacks | Hours |
Rate limiting on APIs is common: plan for 10-100 requests/second depending on the platform.
Key Takeaways
- CSV import is simplest for hundreds of QR codes
- APIs enable programmatic generation integrated into existing workflows
- Templates ensure consistent design across batch-generated codes
- Variable data printing integrates QR images into print production
- Plan for API rate limits when generating thousands of codes
