QR code generator API documentation

Call the API for your QR code

Main URL to call, when you need to create QR code using our API, is resided at https://qr.kopl.pro , where attributes are being sent in GET method calling. The order of attributes added to the API url does not matter. Feel free to use them in your preffered way - do not be bounded by API code.

• Main URL to call, when you need to create QR code using our API, is resided at https://qr.kopl.pro , where attributes are being sent in GET method calling.
• Thus call to https://qr.kopl.pro?data=My first code will be automatically URL encoded (space characters will be replaced to %20) and QR code will be generated.
• When you need your QR code to be replaced its default (black) color to your own, it needs to be added as a parameter to the URL. So in this case, it will look like https://qr.kopl.pro?data=My first code&forcolor=125-17-206 where values 125-17-206 stands for RGB values of the QR code color.
• When you need your QR code having own logo, just add to API's URL yet attribute logo with the address of the image, linkable at internet. Please, be aware, that the logo on the url address cannot be prevented to hotlinking. So in this case, it would be  https://qr.kopl.pro/index.php?data=My%20first%20code&forcolor=125-1-207&logo=https://www.kopl.pro/images/kopl_logo_pruhledne.png&size=10
  
• And finnaly, there is an option to get bigger or smaller QR code when the attribute of size is being used. You can give it a try at  https://qr.kopl.pro/index.php?data=My%20first%20code&forcolor=125-1-207&logo=https://private-inn.cz/templates/privateinn/images/169459841-0.png&size=10
