how to Copy buyer email address to Order details field in PayPal order

@beinhd The buyer email address can be displayed below the products like this:

Keep in mind this may be visible to buyers in their PayPal confirmation mails. But to achieve it you can use this code snippet:

/**
 * Retrieves the email address from the WooCommerce Checkout or Order.
 * 
 * This function checks if there's an order awaiting payment to get the billing email.
 * If not, it fetches the email from the checkout form data.
 *
 * @return string The billing email address.
 */
function get_wc_checkout_email() {
    if ($order_id = WC()->session->get('order_awaiting_payment')) {
        $order = wc_get_order($order_id);
        return $order->get_billing_email();
    } else {
        return WC()->checkout()->get_value('billing_email');
    }
}

/**
 * Modifies the PayPal order payload to include an additional line item representing the buyer's email.
 *
 * The function adds a line item with the buyer's email as a product with a zero price.
 * It ensures that the currency code of this item matches that of other items in the order.
 *
 * @param array $patches_array The original payload for modifying a PayPal order.
 * @return array The modified payload with the additional line item.
 */
function customize_paypal_order($patches_array) {
    $email = get_wc_checkout_email();

    // Default currency code, used if no other items are found from which to infer the currency.
    $currency_code = 'USD';  

    // If items exist in the payload, use the currency code of the first item.
    if (isset($patches_array[0]['value']['items']) && !empty($patches_array[0]['value']['items'])) {
        $currency_code = $patches_array[0]['value']['items'][0]['unit_amount']['currency_code'];
    }

    // Define the line item for the email.
    $email_item = array(
        'name'        => $email,
        'quantity'    => 1,
        'sku'         => 'Buyer email',  // SKU for internal tracking
        'unit_amount' => array(
            'currency_code' => $currency_code,
            'value'         => '0.00',  // Zero price to ensure it doesn't affect the order total
        ),
    );

    // Append the new email item to the existing list of items.
    if (isset($patches_array[0]['value']['items'])) {
        $patches_array[0]['value']['items'][] = $email_item;
    } else {
        $patches_array[0]['value']['items'] = array($email_item);
    }

    return $patches_array;
}

// Register the function to modify PayPal order data just before it's sent.
add_filter('ppcp_patch_order_request_body_data', 'customize_paypal_order', 10);
