Access the complete range of Critizr features for your websites.

The Web SDK is an essential prerequisite for adding Critizr web widgets. It also allows our various interfaces to be opened using a JavaScript method or a GET parameter.


Critizr Integration

Critizr provide a Software Development Kit (SDK) that will ease the integration of our widgets.
To integrate Critizr SDK on your website, you just have to Copy/Paste this code at the end of the <body> tag of all the pages you wish to include our tools:

<script type="text/javascript">
    (function (i, s, o, g, r, a, m) {
        i[r] = i[r], a = s.createElement(o), m = s.getElementsByTagName(o)[0];
        a.async = 1;
        a.src = g;
        m.parentNode.insertBefore(a, m)
    })(window, document, 'script', 'https://static.critizr.com/widgets/<API_KEY>.js', 'cz');


SDK configuration

Beware the part <API_KEY> should be replaced by your own API_KEY provided by Critizr.



Our SDK is loaded asynchronously (with the a.async = 1;) and will not prevent the other elements of the web page from loading.


Add the Web SDK to your website

The Critizr Web SDK is compatible with all tag management tools (TagCommander, Google Tag Manager...).

Common cases

Implementing a widget in your webpage

When adding the following code, the Critizr SDK will parse the code of the page to find all <a> HTML tags with the class critizr-widget and change it to the desired interface with :

  • href the interface you chose
  • data-type widget type (embed compatible only)
  • data-params JSON object to configure the widget
<a class="critizr-widget",


Transmitting configuration values

Configuration values are transferred to the Critizr widgets via a JSON object, which you incorporate into your widget's data-params attribute:
<a href="..." data-type="..." data-params='{"key":"value"}'>

The syntax of your JSON object must be fully valid in order for the values to be transmitted correctly. In particular, pay close attention to ensuring that your keys and values are surrounded by double quotes " and never leave any commas at the end of a table or object. A tool like JSONLint could help you.

Triggering a widget in Javascript

Critizr SDK comes with a set of Javascript functions for a more advanced implementation of Critizr within your website.

CritizrSDK.open(widgetType, posId, params)
