Put a QR code generator in your website with just one line of code
It doesn't get easier than this. We published our QR Code API to enable the creation of a 'white label' QR code generator, making it appear as if the QR codes are generated by your website. Webmasters and developers of popular blogging and content management systems indicated that it was still a bit to complex for them and was it possible to make it easier.
The solution QR4 came up with is a highly configurable QR code generator that lives in an 'iframe'
on any page in your website and can be activated with one simple 'copy and paste' line of code.
<iframe width="600" height="300" src="https://www.qr4.nl/igen.aspx?key=MYKEYVALUE" frameborder="0"></iframe>
Copy the iframe line above and paste it into HTML page, anywhere in the 'body', remember to replace the MYKEYVALUE with a valid key that you can get at the QR Code API key generator. If you already have a key for the API it will work for the iframe generator as well.
The Iframe QR code Generator should look like this in your web page
Iframe configuration
Nearly all presentation elements of the generator can be managed if required. Without any additional parameters the generator will function as show above, but lets have a look at what we can change to suit us and our website.
NOTE: All parameters are optional, parameters can be appended as needed in no particular order. In the examples below replace MTKEYVALUE with your key.
| Parameter |
Description |
| CSS |
You can control fonts, colours, spacing and size of elements by directing the generator to your own CSS style sheet for presentation. We recommend you download the default stylesheet file, adapt it as needed and point the generator to your new CSS file on your server.
Parameter: css
Value: url to css to use
Example: https://www.qr4.nl/igen.aspx?key=MYKEYVALUE&css=https://www.mysite.com/mycss.css |

| Title text |
You can change the title or header text of generator to suit you. Referencing it in the request but supplying no text will make it dissapear.

Example: https://www.qr4.nl/igen.aspx?key=MYKEYVALUE&title=My Simple QR Generator
