API Documentation

To create a QrCode for an email id with prepopulated subject and body use something like the following

   GET https://api.fungenerators.com/qrcode/email

   Parameters
       [email protected]
       format=png
       subject=Qrcode
       body=Qrcode%20Generated%20from%20Fun%20Generators

It should generate a response like this

{
  "success": {
    "total": 4
  },
  "contents": {
    "encoding": "base64",
    "format": "png",
    "text": "mailto:[email protected]?subject=Qrcode&body=Qrcode+Generated+from+Fun+Generators",
    "content": "data:image/png;base64,iVBORw0KGgoAAAANS..."
  },
  "copyright": {
    "url": "https://fungenerators.com",
    "year": "2024"
  }
}

Displaying the returned base64 encoded image

Here is an example to using the base64 encoded image in javascript.

var image = new Image();
image.src = apiresult.contents.content;
document.body.appendChild(image);

In PHP saving the returned base54 encoded image to a image file will look something like this.

$img_string = $result['contents']['content'];
$data = explode(',',$img_string);
file_put_contents("qrcode.png",base64_decode( $data[1] ));

API Rate Limiting for QRCode Generation and Decoding API

Some of our API calls may be public(requires free API key) , while others requires paid subscription. To maintain our serice levels both public and private API endpoints are ratelimited. Please consult your specific plan that you subscribed to for the rate limit details.

Authenticating with the QRCode Generation and Decoding API

Currently we support API Key based authentication. Please set your Autorization Bearer request header with value of your API key. Alternatively you can also pass api_key= as a request parameter, though we strongly discourage this mode of passing the key, since it will allow others to see your key.

In curl this would mean sending the Authorization header like below.

            
 curl -i <url> -H "Authorization: Bearer <api_key>"
            
            

If you are using PHP.

            
$authorization = "Authorization: Bearer <api_key>";
$ch = curl_init('<url>'); // Initialise cURL
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json' , $authorization ));
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST"); // OR GET
$result = curl_exec($ch);
curl_close($ch);
            
            

In javascript you can use headers key to add the authorization header

            
$.ajax({
   url: '<url>'
   type: 'GET',
   contentType: 'application/json'
   headers: {
      'Authorization': 'Bearer <api_key>'
   },
   success: function (result) {
       // CallBack(result);
   },
   error: function (error) {

   }
});
