Conversion event tracking

Always-on rule for conversion-event-tracking  ·  Source

• Use the event names view_item, add_to_cart, begin_checkout, add_shipping_info, add_payment_info, purchase, and refund.
• Send items with a stable item_id for the purchasable unit.
• Set value to the sum of item price times quantity. Exclude tax and shipping. Send those as their own purchase fields.
• Require an ISO currency whenever value is set.
• Fire purchase only after payment is confirmed. transaction_id is the order number and must be non-empty.
• Reuse that transaction_id on reload and on refund. Do not mint a new id per page view.
• Do not put customer name, email, or phone on the event.
• Follow the shop's consent settings before loading advertising tags.
• Run scripts/check-event.mjs on the payload. It does not call an analytics service.
