QR types

QR Code Types

Each type is automatically encoded using the correct protocol (WIFI:, SMSTO:, mailto:, VEVENT, etc.). URL and vCard codes are dynamic (vCard opens a hosted contact page); WiFi, email, SMS, text, and event codes are static — the payload is encoded directly into the image. You can also pass a pre-encoded payload via target.destination if you prefer to encode yourself.

How it works

What Is a QR Code API?

Where to Integrate the QR Code API in Your Systems

Teams plug the QR code API into the systems that already generate documents and messages — so every receipt, email, invoice, or check-in pass can carry a unique code. Four patterns cover most integrations:

SDKs & client libraries

SDKs & Client Libraries — Use It From Any Language

The QR code generator API is a standard JSON REST API — no SDK required. If your language has an HTTP client, you're ready: requests in Python, fetch in JavaScript, cURL from the shell. Here's a complete workflow — create a dynamic code, change its destination later, and download a print-ready PNG:

import requests

API = "https://api.useqrkit.com/v1"
HEADERS = {"Authorization": "Bearer qr_live_YOUR_KEY"}

# 1. Create a dynamic QR code
qr = requests.post(f"{API}/qr-codes", headers=HEADERS, json={
    "name": "Spring promo",
    "target": {"type": "url", "destination": "https://example.com/promo"},
}).json()
print(qr["id"], qr["image_url"])

# 2. Change the destination later — no reprint needed
requests.patch(f"{API}/qr-codes/{qr['id']}", headers=HEADERS, json={
    "target": {"destination": "https://example.com/new-promo"},
})

# 3. Download a print-ready PNG
png = requests.get(
    f"{API}/qr-codes/{qr['id']}/download",
    headers=HEADERS,
    params={"format": "png", "size": 2000},
)
with open("qr-code.png", "wb") as f:
    f.write(png.content)

The REST surface covers the full product: dynamic QR code creation, destination updates, scan analytics, folders, and batch creation of up to 1,000 codes per request. The full endpoint reference with an interactive playground lives at docs.useqrkit.com.

Pricing

API Access & Rate Limits

API access is included with every paid subscription — no separate API add-on or per-request fees. Your plan determines your request limits:

All paid plans include the full API feature set: static and dynamic QR codes, all 7 QR types, SVG and PNG output, logo embedding, custom colors and gradients, and scan analytics. Batch creation is available from Plus up. High-volume teams and agencies get the 50,000-request Ultra and Agency tiers. See pricing plans for full details and current rates.

Migration

Migrating from Google Image Charts QR API

Google deprecated its Image Charts API (including QR code generation) in 2019. If you're still using chart.googleapis.com URLs, the migration path is one create call per code: instead of hot-linking a throwaway chart URL, you create the code once and embed the permanent hosted image it returns.

https://chart.googleapis.com/chart?cht=qr&chs=200x200&chl=Hello+World

curl -X POST "https://api.useqrkit.com/v1/qr-codes" \
  -H "Authorization: Bearer qr_live_YOUR_KEY" \
  -d '{"target": {"type": "text", "text": "Hello World"}}'
# → returns a permanent image_url to embed

Unlike a fire-and-forget chart URL, every code you create is stored in your workspace — you can rename it, restyle it, and organize it later. QRKIT also supports features Google's API never offered: custom colors and gradients, logo embedding, SVG output, and dynamic QR codes with scan analytics and editable destinations.
