Hi,
We did develop an integration with Intuit Payment Gateway, and it was working fine... That is until they decided to stop supporting it and created a new one which is not backward compatible with the previous payment gateway.
We support already more than 70 payment gateways. If every one was changing their payment gateway API every few years, we wouldn't get any work done.
We do as much as we can, but we can't do everything on our own.
If you need a payment gateway integration done rapidly, them you can pay a developer to develop it for you.
Some of our partners will be able to do that for you:
www.hikashop.com/home/our-partners.html
Also, third party developers who already developed payment plugins for HikaShop would also be able to do that.
Or if you're a developer, you can do it yourself. We have documentation available for that:
www.hikashop.com/support/support/documen...r-documentation.html
If there is one area where others can contribute code easily, it's the payment plugins. You have plenty of documentation, plenty of examples with all the payment plugins available freely in HikaShop and we'll be happy to answer your questions.
