Create QR Codes

Create a dynamic QR code for URLs and managed destinations, or a static QR code for WiFi payloads.

POST https://createqr.app/api/v1/create

Send JSON only. For key auth, header is best practice. Body key fields are there for compatibility with existing integrations.

Quickstart (cURL)

This dynamic URL example is the fastest hello-world path.

curl -sS -X POST 'https://createqr.app/api/v1/create' \
  -H 'Content-Type: application/json' \
  -H 'Authorization: Bearer ck_live_XXXXXXXXXXXXXXXXXXXXXXXX' \
  -d '{"data":"https://createqr.app","qrtype":"dynamic"}'

Auth & compatibility

  • Recommended: Authorization: Bearer <key>
  • Also accepted: X-API-Key
  • JSON fallback: apikey or api_key
  • Content-Type must be application/json
  • Non-POST methods return 405 method_not_allowed

Error responses, limits, and retries

Every response includes request_id. Keep it when contacting support so we can debug quickly.

Typical error envelope

Retry strategy

  • 429 rate_limited: retry with exponential backoff plus jitter.
  • Honor Retry-After when present.
  • 429 monthly_quota_exceeded: wait for quota reset or use a key with quota left.
  • 5xx: retry with capped attempts, then alert your team.

FAQ

Short answers for the questions we see most in integrations.

How many API requests can I run?

The API is Business-only. The monthly quota comes from your active plan and key overrides. Default Business seed is high, and admins can fine-tune per key.

Can I send API keys in JSON body?

Yes. Header-based auth is recommended, but compatibility body fields apikey or api_key are also accepted.

Can I create static QR codes through the API?

Yes, but static mode is limited to WiFi payload strings. Use dynamic mode for URLs, PDFs, menus, apps, social pages, and other managed destinations.

Do API-created QRs show up in my dashboard?

Yes. Every successful create is saved in your account and can be managed like any other QR.

What happens when I hit limits?

You receive JSON errors. For 429 responses, respect Retry-After and use exponential backoff with jitter.

Can I delete a QR from another account?

No. Delete and list are scoped to the authenticated API-key owner.

Security best practices

  • Never expose raw API keys in browser JavaScript, mobile bundles, or public repositories.
  • Use API key IP allowlists to lock usage to trusted servers.
  • Log request_id together with your own trace IDs for faster incident triage.
  • Rotate keys on a schedule and immediately after credential leaks.
Open API key manager
