Hi,
On our end, we develop payment plugins for some clients who are ready to pay for the costs of development.
No one has manifested himself for that payment platform so far.
So unless someone is willing to pay for the development we won't do it in under 90 days as we are working on other things for HikaShop.
Of course, anyone can develop payment plugins for HikaShop and we have a developer documentation in order to help on that.
So you could also do it yourself or have it done by a 3rd party developer. In that last case, I invite you to post such thread on our commercial jobs area.
