Hello,
Thanks for your message. The payment framework of VikBooking can definitely be extended through custom WordPress plugins that implement the native hooks of VikBooking.
This means that any existing WordPress plugin for a specific bank gateway, like the Tunisian service that your client needs to integrate, may be built for WooCommerce, and so this would not work with our plugin VikBooking, I’m sorry. This is because our Vik plugins have their own and stand-alone framework that is documented on our official website under the section “Help – Documentation – Developers – Payment Plugins”.
We invite you to get in touch with our team through our website should you have any other questions, especially because the payment framework is a feature available only in the commercial/Pro version of the plugin.
Thank you,
The VikWP Team
