This plugin is a special product – a payment gateway extension – and requires the Osclass Pay Plugin v4.1 or higher to be installed. It will not function without the required plugin.
Some gateways restrict sandbox access, which may require small adjustments during integration.
If you face issues, please open a support ticket and include sandbox API keys so we can assist you efficiently.
Demos are not available for all payment gateways due to technical limitations, such as currency requirements or limited access to sandbox environments.
Most gateways are integrated using the redirect method — the customer is redirected to the gateway’s hosted checkout page and then returned to your site after completing the payment.
Information about payment gateways (such as supported countries, currencies, and business models) has been sourced from the official gateway websites and may not always be up to date. Please verify all necessary details directly with the gateway before making a purchase.
Ideally, obtain your API keys and an approved account prior to purchasing any plugin extension. We are not affiliated with the payment gateways, have no influence over their onboarding process, and cannot provide support related to it.
