Better to set notifications for the payments (Its optional, but with it you can be sure that your website will receive the response).
To make that, you need to go to your GoPay My account page at https://gopay.com/, and find E-shop settings:
– Api version to V3
– Notification URL to https://website.com/wc-api/wls_woo_gopay_payments_gateway?gopay_notify=1 Where website.com is your domain name.
You anytime can get notification URL from WebLight GoPay plugin Settings Page
