Hi,
We did develop an integration for iPay88 and Vik Booking, but unfortunately at the moment this is not available for the WordPress version of Vik Booking.
As you know, there’s a Joomla version of Vik Booking on our other dedicated website, and there we have already an integration for iPay88.
Porting this payment gateway from Joomla to WordPress would not be a problem for our programmers, but please be aware of the fact that only the Pro version of Vik Booking for WordPress supports custom payment plugins.
The payment framework of Vik Booking can be extended to support any bank gateway integration, but it requires a specific WordPress plugin that declares some hooks/actions to start the transactions, capture the payments and process the responses. In case you are a developer, you can find a technical documentation on our website that explains how to create custom payment plugins for the Pro version of Vik Booking.
We invite you to get in touch with our team by using the contact form on our website in case you would like us to add the integration for iPay88 also on WordPress. Thank you.
