Thanks for sharing the details, but that is not a link, nor is it a modification you could achieve so easily, I’m sorry.
The step number 3 is the final step of the booking process, and it’s called “booking confirmation”. What you are talking about is actually a form, not a link. It is technically impossible to change the action attribute of that form, because it points to the Controller that is responsible of actually storing the new reservation. If you were to change “link” (it’s not a link, it’s a form), then you would break the whole booking process, and no bookings will be saved.
Also, VikBooking is a stand-alone plugin and does not rely on WooCommerce in any way. The same thing goes for any other third-party plugin. This was just to say that VikBooking has got its own payment framework, which can be extended by creating WordPress native plugins that declare the proper hooks for VikBooking in order to install a new payment method with the instructions about how to start a transaction and how to validate the payment response. WooCommerce has got nothing to do with VikBooking in this case.
What you need to do in order to implement a direct connection with your local payment gateway is actually to code a custom payment plugin for VikBooking. There are no links that should be modified or overrides that should be created. You need a custom payment plugin for VikBooking and your local bank that is capable of starting a payment transaction and to validate the payment response.
We invite you to follow the instructions for developers on our website that explain how to code a custom payment plugin for VikBooking. This is the only way to achieve your connection with your local bank.
We hope this was helpful!
