Review Start

Fire whenever a user modifies the first field on a review widget.

An item object should be included, but not as a separate property or array. The keys and values of the item should be rolled into the base object being pushed...hence the spread operator syntax used in the JS code below.

Javascript Code

// When:
// User modifies the first field on a review widget

// Code:
window.dataLayer = window.dataLayer || [];
dataLayer.push({ event_data: null });  // Clear the previous event_data object.
dataLayer.push({
  event: 'review_start',
  event_data: {
    item_id: "<item_id>" // REQUIRED | string | ex. 12345
  }
});
