Event-based integration

The event-based integration allows you to retrieve loaded placements and listen to the events that they emit.

The selection process exposes a method called Selection.on that allows you to subscribe to events emitted by any placement in the selection. Alternatively, each placement can be subscribed to separately after obtaining their instances from a promise returned by Selection.getPlacements method. This resolves with placements once the selection process finishes but before they are loaded on a page

Event types#

Rokt supports various event types for users to subscribe to:

Event TitleDefinition
OFFER_ENGAGEMENTdescribes user engaging positively or negatively with an offer
POSITIVE_ENGAGEMENTdescribes user engaging positively with an offer or catalog item
PLACEMENT_CLOSEDdescribes when a placement closes
PLACEMENT_INTERACTIVEdescribes the moment when placement has been rendered and is interactable
PLACEMENT_READYdescribes when the placement is ready to display but has not rendered content yet


// selectionconst selection: Selection;
// Listen for when the placement becomes interactive/ready to displayselection.on('PLACEMENT_INTERACTIVE').subscribe(() => {  // Logic to run after Placement has become interactive});
// Listen for when the placement iframe resizesselection.on('PLACEMENT_RESIZE').subscribe(function () {  // Logic to run after Placement resizes});

Google Tag Manager integration example#

// Listen for when user engages positively OR negatively with an offerselection.on("OFFER_ENGAGEMENT").subscribe(() => {  window.dataLayer?.push({    ROKT_OFFER_ENGAGEMENT: true,  });});
// Listen for when user engages positively with an offerselection.on("POSITIVE_ENGAGEMENT").subscribe(() => {  window.dataLayer?.push({    ROKT_POSITIVE_ENGAGEMENT: true,  });});
// Listen for when user closes out of the placementselection.on("PLACEMENT_CLOSED").subscribe(() => {  window.dataLayer?.push({    ROKT_PLACEMENT_CLOSED: true,  });});
