Custom websites: the purchase event

What your thank-you page needs to push so PixelFly can hold the order and send it later.

On WooCommerce you do not need this page — the plugin pushes this event for you. This is for custom-built stores.

Push this on the thank-you page, once per order

dataLayer.push({ ecommerce: null });
dataLayer.push({
  event: 'purchase',
  eventId: 'purchase_1042',            // unique per order (Meta keeps one copy)
  payment_method: 'cod',               // or 'bkash', 'card', …
  ecommerce: {
    transaction_id: '1042', value: 1580, currency: 'BDT', shipping: 80,
    items: [{ item_id: '189', item_name: 'Cat Toy', price: 750, quantity: 2 }]
  },
  user_data: { email: 'a@b.com', phone_number: '01712345678', first_name: 'Rina', last_name: 'Begum' }
});

What each part does

Field	Needed?	Why
`payment_method`	Required	Decides whether the order is held. See the rule below.
`value` and `currency`	Required	Without them a confirmed order cannot be sent, and waits as missing purchase data.
`transaction_id`	Strongly advised	How you confirm the order later. Without one it is held as `NOID-…` and can only be approved by hand.
`eventId`	Strongly advised	Stops Meta counting the same purchase twice.
`user_data`	Advised	Email and phone are how Meta matches a confirmed order back to the person who saw your ad. Fewer fields, weaker matching.
`items`	Optional	Product-level reporting and catalogue matching.

What counts as a COD order

PixelFly treats the order as cash on delivery when payment_method is:

exactly cod;
anything containing cash_on_delivery or cash on delivery;
or missing entirely — held on the safe side, because an unknown payment method is more often COD than not.

Anything else is prepaid and fires at checkout as usual. If your prepaid orders are being held, this field is the first place to look.

Place one prepaid and one COD test order and confirm the held one appears with its value, products and customer.
