Okay, next I'll start with Technical interface details, andRate and cost optimisation, andFrequently Asked Questions The three areas continue to go deeper to help you land a Vietnamese payment solution in WooCommerce more efficiently.

I. Key steps in technology docking

1. Local payment gateway configuration (VNPAY as an example)

• parameterisation: Fill in the Merchant ID in the WooCommerce backend (vnp_TmnCode), secure hash key (vnp_HashSecret) and enable test mode.
• Callback URL Configuration::

  // 示例代码片段（添加到主题的functions.php）
  
  add_action('init', 'handle_vnpay_return');
  
  function handle_vnpay_return() {
  
    if (isset($_GET['vnp_ResponseCode'])) {
  
      $order_id = $_GET['vnp_TxnRef'];
  
      $order = wc_get_order($order_id);
  
      if ($_GET['vnp_ResponseCode'] == '00') {
  
        $order->update_status('completed', __('Payment via VNPAY successful', 'woocommerce'));
  
      }
  
    }
  
  }

III. Solutions to common problems

• ✔️ checkpoint:
  1. Whether WooCommerce's IPN settings are turned on (Woocommerce → Settings → Payments → Gateway name)
  2. Is the PHP version ≥ 7.4 (older versions may cause callbacks to fail)

Q2: "Vietnamese Dong (VND) is displayed in decimal places"

-- Direct modification of database currency format (performed after backup).

UPDATE wp_options SET option_value = '0' WHERE option_name = 'woocommerce_price_num_decimals';

Q3: "ZaloPay can't evoke the app"

• ✅ Compulsory programme:
  Enable "Universal Links" in the ZaloPay plugin settings and submit the Apple App Site Association file to the website root directory.
