Headless widgets
Headless widgets enable you to create fully customizable widgets in terms of both design and behavior. These widgets rely on the Didomi’s widgets engine, so they feature authentication management, analytics, content rendering, purpose and preference choices, and saving upon clicking or after user confirmation.
The following set of elements, events and methods are available for generating the widget and collecting end-user consent and preference choices.
Custom elements are HTML components used to display the content of your widget as well as wrap your own HTML elements to handle specific communication with the Didomi API. Please refer to this documentation for more information about custom elements.
Custom events are synthetic events in Javascript that can be dispatched to our SDK.
Use custom events to communicate with our custom elements to wrap your code and handle all logic, analytics and API requests.
Public methods are SDK methods that are made available to facilitate your interactions with our SDK, including getting information from the widget configuration and from the current user consent state.
Event listeners are JavaScript methods that set up a function to run whenever the specified event is delivered to the target.
You can use event listeners to provide UI feedback to your end-users, handle retries, and more. Since custom events don't support callbacks, this is how you can know the current state (loading, success, error) of an action that has been emitted.
To use a Headless widget, set the
format to embeddable and headless to true when creating the widget via the API.Once created, the widget can be edited in the Didomi Console or using API. All sections are supported by a Headless widget, except for Look and Feel.
POST https://api.didomi.io/widgets?organization_id=YOUR_ORG_ID
{
"name": "My Headless widget",
"format": "embeddable",
"headless": true
}
To use a Headless widget, you first need to load our SDK. We recommend integrating the SDK loader at the top of your HTML.
💡 The SDK loader code to embed is available in the Didomi Console once you have created an
embeddable widget.<script>
window.didomiConfig = {
apiKey: "YOUR_API_KEY",
app: { apiKey: "YOUR_API_KEY" },
components: {
version: 2,
},
widgets: [],
};
</script>
<script
type="text/javascript"
async="true"
charset="utf-8"
src="https://sdk.privacy-center.org/v2/loader.js"
></script>
After the SDK is ready, you can access the widget configuration and the entities enabled within the widget.
To display the Headless widget once the container and entities are loaded you need to add the
didomi-container-headless custom element.window.didomiWidgetsOnReady = window.didomiWidgetsOnReady || [];
window.didomiWidgetsOnReady.push(async (DidomiWidgets) => {
const container = await DidomiWidgets.getContainerById("widgetId");
const entities = await container.getEntities();
});
<didomi-container-headless id="widgetId">
// Add your HTML here
</didomi-container-headless>
To avoid a flickering effect while the SDK is loading, you can use this CSS snippet. This can be applied to any custom element:
didomi-if-authenticated:not(:defined) {
display: none;
}
didomi-if-not-authenticated:not(:defined) {
display: none;
}
