Implement Backend

Once Collect.js tokenizes the card, your server receives a payment_token and submits it to the CyoGate API to process the payment.

PHP Example

<?php
$post = array(
    'security_key'  => YOUR_PRIVATE_KEY,
    'type'          => 'sale',
    'amount'        => '29.99',
    'payment_token' => $_POST['payment_token'],
    'order_id'      => 'ORDER-' . time(),
    'firstname'     => $_POST['firstname'] ?? '',
    'lastname'      => $_POST['lastname']  ?? '',
    'email'         => $_POST['email']     ?? '',
);
$ch = curl_init('https://secure.cyogate.net/api/transact.php');
curl_setopt($ch, CURLOPT_POST,           true);
curl_setopt($ch, CURLOPT_POSTFIELDS,     http_build_query($post));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, true);
$response = curl_exec($ch); curl_close($ch);
parse_str($response, $result);
if ($result['response'] == '1') {
    // Approved
    echo json_encode(['success' => true, 'txid' => $result['transactionid']]);
} else {
    echo json_encode(['success' => false, 'message' => $result['responsetext']]);
}
?>

Python Example

import requests
from urllib.parse import parse_qs

payload = {
    'security_key':  PRIVATE_KEY,
    'type':          'sale',
    'amount':        f'{amount:.2f}',
    'payment_token': payment_token,
    'order_id':      order_id,
}
response = requests.post('https://secure.cyogate.net/api/transact.php', data=payload, timeout=30)
result = {k: v[0] for k, v in parse_qs(response.text).items()}
