​
1. Get your API key

Sign in to QRKit and open Dashboard → API Keys. Create a new key with qr:read and qr:write scopes (API access is included on all paid plans).
Your full API key is only shown once at creation. Copy it and store it securely.

​
2. Create a QR code

Make your first API call to create a dynamic QR code: 
curl -X POST https://api.useqrkit.com/v1/qr-codes \
  -H "Authorization: Bearer qr_live_your_key_here" \
  -H "Content-Type: application/json" \
  -d '{
    "name": "My Website",
    "type": "dynamic",
    "target": {
      "type": "url",
      "destination": "https://example.com"
    }
  }'

​
3. View the response

A successful request returns the created QR code object: 
{
  "id": "qr_123",
  "object": "qr_code",
  "kind": "dynamic",
  "name": "My Website",
  "type": "url",
  "short_code": "AB3D5",
  "short_url": "https://scan.useqrkit.com/AB3D5",
  "target": {
    "type": "url",
    "destination": "https://example.com"
  },
  "design": {
    "colors": { "foreground": "#000000", "background": "#ffffff" },
    "gradient": null,
    "shapes": { "body": "square", "eye_frame": "square", "eye_ball": "square" },
    "eye_colors": null,
    "has_logo": false,
    "transparent_background": false
  },
  "folder_id": null,
  "tags": [],
  "image_url": "https://img.useqrkit.com/qr-AB3D5-1717000000000.svg",
  "download_url": "/v1/qr-codes/qr_123/download",
  "is_active": true,
  "scan_count": 0,
  "utm": null,
  "created_at": "2026-01-15T10:30:00Z",
  "updated_at": "2026-01-15T10:30:00Z"
}
The QR image itself encodes short_url — print it once and change the destination any time with Update QR Code. WiFi, email, SMS, text and event codes are static instead: the payload is encoded directly into the image (no short_url, no scan tracking) and their ids start with sqr_.

​
4. Download the image

Download the QR code image in SVG or PNG format: 
curl https://api.useqrkit.com/v1/qr-codes/qr_123/download?format=png&size=500 \
  -H "Authorization: Bearer qr_live_your_key_here" \
  --output qrcode.png
