🔴 Phase 1 — Core · Cart drop-off insight.

remove_from_cart

When to push

After the server confirms removal (or quantity decrease).

quantity = the amount removed (delta), not the amount remaining.

Example

window.dataLayer.push({ ecommerce: null });
window.dataLayer.push({
  event: 'remove_from_cart',
  ecommerce: {
    currency: 'EUR',
    value: 42.00,        // value removed
    items: [
      {
        item_id: 'BIO-CRM-001',
        item_name: 'Day Cream',
        price: 42.00,
        quantity: 1       // removed
      }
    ]
  }
});

Pitfalls

• ❌ Pushing quantity = remaining instead of removed.
• ❌ Pushing twice if there's an undo button that re-adds (use add_to_cart for re-add).
