Sync unpaid bookings to Google Calendar

Extend WooCommerce Bookings’ Google Calendar integration to include bookings when they enter the Unpaid status. By default, Bookings syncs bookings when they enter Confirmed, Paid, or Complete.

Before you begin

↑ Back to top

Connect WooCommerce Bookings to a Google Calendar and test this customization on a staging site. This filter changes which booking statuses the calendar integration treats as eligible for synchronization; it does not record a payment or change the booking’s status. Events can contain booking and customer information, so limit access to the connected calendar.

Include unpaid bookings

Add this code to a custom plugin or your child theme’s functions.php file:

/**
 * Allow unpaid bookings to sync to Google Calendar.
 *
 * @param string[] $statuses Booking statuses eligible for calendar sync.
 * @return string[]
 */
function example_sync_unpaid_bookings_to_google( $statuses ) {
	$statuses[] = 'unpaid';
	return array_unique( $statuses );
}
add_filter( 'woocommerce_booking_is_paid_statuses', 'example_sync_unpaid_bookings_to_google' );

With the snippet active, create a test booking that enters Unpaid status and confirm that its event appears on the connected calendar. Review the event’s details and test the booking workflow before using this on a live store. This snippet does not perform a bulk sync of existing bookings.
