// In a real scenario, this would be a robust plugin or service.
function sync_new_order_to_hubspot($order_id) {
$order = wc_get_order($order_id);
$customer = $order->get_customer_id() ? new WP_User($order->get_customer_id()) : null;
// Prepare HubSpot contact properties
$contact_properties = [
'email' => $customer ? $customer->user_email : $order->get_billing_email(),
'firstname' => $order->get_billing_first_name(),
'lastname' => $order->get_billing_last_name(),
// Add more properties like phone, address, etc.
];
// Prepare HubSpot deal properties (if tracking deals)
$deal_properties = [
'dealname' => 'Order #' . $order_id . ' - ' . $order->get_billing_last_name(),
'amount' => $order->get_total(),
'closedate' => date('Y-m-d H:i:s', strtotime($order->get_date_completed())),
// Link to contact
];
// Use HubSpot API client (e.g., HubSpot PHP SDK)
// $hubspot_client = new HubSpot\Client\Crm\Contacts\ApiClient(...);
// $hubspot_client->crm()->contacts()->basicApi()->create($contact_properties);
// $hubspot_client->crm()->deals()->basicApi()->create($deal_properties);
error_log("Synced order {$order_id} to HubSpot.");
