I bought a license of Exp:resso Store, with the idea that it supports Rabo OmniKassa payment gateway, as mentioned by Exp:resso itself in there release notes.

Now I want to setup the payment gateway information and notice that it is not available in store 2.x.

So I contacted Exp:resso about this and they said that the payment gateway was dropped as of version 2.x. But they also told me that will look at it at try to re-implement it.

That's what they said 6 weeks ago. But radio silence since that last e-mail.

I e-mailed them a couple of times, but only receiving a default answer but no real answer. In my opinion, the support is very bad voor Exp:resso store.

Hopefully, they well fix my issue. But until then, maybe I have to fix it myself. But how will I be able to do so, of does anyone already have done this? Implementing support for Rabo OmniKassa.

  • i don't know if it's an answer, but you could try to get into contact with Bas van Ginkel (www.ditiserg.nl). he had an omnikassa plugin built a while ago Commented Oct 21, 2014 at 7:27

Usually additional gateways are sponsored before they are developed so you could talk to them about sponsoring the creation of the new gateway.

The docs also mention that Store 2 payment library was rewritten and that not all gateways are supported.

Most officially supported gateways have been included, but any third-party gateways will need to be rewritten in the new format.

Having said that Store uses Omnipay which is an open source payment library so you could easily develop your own Rabo Omnikassa gateway using their API. You can look at the included gateways to see how the payment gateway should be structured.

If all else fails they do have a have a return period, and would probably make an exception if you have passed that threshold.
