I have custom payment button i put on woocommerce checkout page before confirm order page, and it will redirect to confirm order page after the payment have been made.
The url look something like this
mydomainpayment.com/?recipient=someone&amount=' . (string) $ order->get_total() . '&returnurl=myshopdomain.com/(what-parameter-to-put-here-order-id)"><button type="button">Pay With Custom Payment</button></a>';
My question is what parameter to put at behind return url there.
Thank You in advance.
