Events

The Didomi SDK triggers various events to notify you that the user has taken some action (changed their consent status, open the preferences pop-in, etc.) or that an important event has happened.

This section describes what events are available and how to subscribe to them.

Event listeners

The Didomi SDK supports three methods for registering event listeners:

didomiEventListeners (Recommended)

You can register events by adding them to the special window.didomiEventListeners array:

<script type="text/javascript">
window.didomiEventListeners = window.didomiEventListeners || [];
window.didomiEventListeners.push({
  event: 'event.type',
  listener: function () {
    // Your event listener
  }
});

window.didomiOnReady = window.didomiOnReady || [];
window.didomiOnReady.push(function () {
  // Your initialization code (if any)
});
</script>

...

// Embed the Didomi SDK on the page
<script type="text/javascript" src="https://sdk.privacy-center.org/loader.js" async="true"></script>

When the SDK initializes, it collects event listeners from that array and registers them. You must add your event listeners to that array before the SDK gets embedded on the page and before it is ready to guarantee that you do not miss an event. You can also add event listeners to that array after the SDK is loaded and the SDK will automatically pick them up but you will miss events that happen during the SDK initialization.

This is the preferred method of registering event listeners as it guarantees that you do not miss events.

Registering your event listeners should be done outside of the window.didomiOnReady callback to ensure that you receive all events.

If you register events within the window.didomiOnReady callback, you will miss some events like the very first notice.shown that is sent before the window.didomiOnReady callback gets fired.

Didomi.on

The SDK also allows you to register event listeners with the Didomi.on method exposed in its API:

window.didomiOnReady = window.didomiOnReady || [];
window.didomiOnReady.push(function () {
  Didomi.on('event.type', function () {
    // Your event listener
  });
});

While this method is perfectly valid, its main drawback is that your event listener only gets registered once the SDK is ready so that you will miss events fired during the SDK initialization. We recommend using the didomiEventListeners method instead.

React

If you are using our React plugin, event listeners can be passed as props to the DidomiSDK component:

consentHasChanged() {
    // Do something when the consent from the user has changed
}

preferencesClickPurposeAgree(purposeId) {
    // Do something when user agree on a purpose
}

...

<DidomiSDK
    ...
    onConsentChanged={this.consentHasChanged.bind(this)}
    onPreferencesClickPurposeAgree={this.preferencesClickPurposeAgree.bind(this}
/>

Event types

This section presents a comprehensive list of the event types exposed by the Didomi SDK and usage examples.

api.error

Triggered when an error happens while sending an HTTP request to our API for collecting consents, events, metrics, etc.

Listener parameters

context object that contains the following properties:

Key

Description

reason

The reason for the request error.

Possible values: - request.failure when the request fails to be sent for any reason (timeout, no connection, blocked by an extension, etc.) - response.error when we received an error response from the server based on the HTTP response code (>= 400)

An ID identifying the request that failed. Possible values: - createEvent: HTTP request to collect an event after a user action (consent changed, pageview, etc.) - createSignature: HTTP request to sign a Didomi Consent String - getSyncData: HTTP request to get user choices from the backend (sync)

Example

window.didomiEventListeners = window.didomiEventListeners || [];
window.didomiEventListeners.push({
  event: 'api.error',
  listener: function ({ id, reason }) {
    // An API error happened
  }
});

Triggered when the user consent status changes either as the result of a user action or an API call.

Listener parameters

context object that contains the following properties:

Key

Description

action

The user action that triggered the consent change. Possible values: click (explicit click on the buttons), navigate (click to navigate to another page) or external (external call to setUserAgreeToAll)

Example

window.didomiEventListeners = window.didomiEventListeners || [];
window.didomiEventListeners.push({
  event: 'consent.changed',
  listener: function (context) {
    // The user consent status has changed
  }
});

consentHasChanged() {
    // The user consent status has changed
}

...

<DidomiSDK
    ...
    onConsentChanged={this.consentHasChanged.bind(this)}
/>

Triggered when a pending content is added or removed from the queue through the method Didomi.setPendingConsentForEntityById or cleared through Didomi.savePendingConsents.

Listener parameters

Key

Description

pendingConsents

The list of pending consents

Example

window.didomiEventListeners = window.didomiEventListeners || [];
window.didomiEventListeners.push({
  event: 'consent.pendingchanged',
  listener: function ({ pendingConsents }) {
    // The number of pending consent has changed
  }
});

integrations.consentpassedtodfp

Triggered when the user consent status has been passed to Google DFP / AdSense / AdExchange. This is only triggered when the Google DFP / AdSense / AdExchange integration is enabled on your website. Visit that section for more information.

Listener parameters

The listener is provided with a single data object that has the following properties:

Property

Type

Description

consentStatus

boolean

Consent status of the user for the vendor Google.

true if the user has given consent.

false if the user has denied consent.

undefined if the user has not made a choice yet.

index

number

The index is the number of the event on the page. There is always a first event that gets triggered with index 0 on page load. More events can be triggered if the user changes their consent preferences on the page. The index gets incremented by 1 for every event triggered.

Example

window.didomiEventListeners = window.didomiEventListeners || [];
window.didomiEventListeners.push({
  event: 'integrations.consentpassedtodfp',
  listener: function (data) {
    // Consent has been passed to Google
    // Load or refresh ads as needed with DFP, Prebid, etc.
    // `data.consentStatus` contains the current consent status of the user (true/false/undefined)
    // `data.index` contains the index of the event (integer)
    if (data.index === 0) {
      // This is the very first event on the page that gets triggered on page load
    } else {
      // This is an event that happens later on the page, after a user action (user giving consent or changing their preferences)
    }
  }
});
