Conversion postback snippets

The network records a conversion only after your backend fires a postback to the edge. Below are minimal snippets you can adapt — each one assumes you've stored the network-issued click_id from the landing page (in a cookie, hidden field, or query string).

Plain PHP

$click_id = $_COOKIE['tofz_click'] ?? null;
if ($click_id) {
  $params = http_build_query([
    'cid'            => 12,
    'click_id'       => $click_id,
    'transaction_id' => $order_id,
    'event'          => 'purchase',
    'payout'         => intval($order_total * 100),
    'currency'       => 'USD',
  ]);
  // Fire and forget — don't block checkout on the network's response.
  @file_get_contents("https://edge.trackofferz.com/v1/conv?$params", false,
    stream_context_create(['http' => ['timeout' => 2]]));
}

Node / Next.js API route

export async function POST(req: Request) {
  const { orderId, total, currency, clickId } = await req.json();
  if (!clickId) return new Response('ok'); // organic, nothing to do
  const params = new URLSearchParams({
    cid: '12',
    click_id: clickId,
    transaction_id: orderId,
    event: 'purchase',
    payout: String(Math.round(total * 100)),
    currency,
  });
  // Don't await — checkout shouldn't depend on the network.
  void fetch(`https://edge.trackofferz.com/v1/conv?${params}`, {
    method: 'GET',
    signal: AbortSignal.timeout(2000),
  });
  return new Response('ok');
}

Shopify (Order Status JavaScript)

In Settings → Checkout → Order status page → Additional scripts:

<script>
  var click_id = window.localStorage.getItem('tofz_click');
  if (click_id) {
    var img = new Image();
    img.src =
      'https://edge.trackofferz.com/v1/conv?cid=12'
      + '&click_id=' + encodeURIComponent(click_id)
      + '&transaction_id=' + Shopify.checkout.order_id
      + '&event=purchase'
      + '&payout=' + Math.round(Shopify.checkout.total_price * 100)
      + '&currency=' + Shopify.checkout.currency;
  }
</script>

WooCommerce (functions.php)

add_action('woocommerce_thankyou', function($order_id) {
  $order = wc_get_order($order_id);
  $click_id = WC()->session->get('tofz_click');
  if (!$click_id) return;
  $params = http_build_query([
    'cid'            => 12,
    'click_id'       => $click_id,
    'transaction_id' => $order_id,
    'event'          => 'purchase',
    'payout'         => intval($order->get_total() * 100),
    'currency'       => $order->get_currency(),
  ]);
  wp_remote_get("https://edge.trackofferz.com/v1/conv?$params", ['timeout' => 2]);
});

Stripe webhook (recommended for accuracy)

Server-side webhooks are the most reliable trigger. In your payment_intent.succeeded handler:

const click_id = paymentIntent.metadata.tofz_click;
if (click_id) {
  const params = new URLSearchParams({
    cid: '12',
    click_id,
    transaction_id: paymentIntent.id,
    event: 'purchase',
    payout: String(paymentIntent.amount),
    currency: paymentIntent.currency.toUpperCase(),
  });
  await fetch(`https://edge.trackofferz.com/v1/conv?${params}`);
}
