Payment Plugin: G2A Pay
Before you will be able to receive payments for your subscription you need to activate it in Merchant Panel, please follow this link https://pay.g2a.com/merchant/subscriptions and complete required steps, please also keep in mind that you need to be a fully activated merchant to complete the process.
To be able to receive these IPNs, first you have to set up an appropriate IPN listener page URL where messages will be forwarded.
To do this, enter https://pay.g2a.com and navigate to Settings > Merchant.
G2A PAY then sends notifications of all transaction-related events to that URL:
