How to create custom payment gateway for Forte?

Hi all, I am trying to setup a new payment gateway for Forte. I am unsure if v5 is using omnipay or if I need to make something different. Has anyone successfully integrated Forte ACH/Credit card payments into their invoiceninja? If not, which of the developer functions that forte offers would I use for my integration? Forte Payment Systems Developer Documentation

Thanks

Hi,

There’s some info about developing a custom gateway here:
