ETS eMoney?

Anyone used ETS Corporation's EMoney ECOM Gateway ?

I'm working on a project that will have to interface to it and if the
work has already been done was
hoping not to re-invent the wheel.

Failing that, which payment gateway gem option is better -
ActiveMerchant or Payment, or are there others ?

I'm willing to add the work done for this to whichever option we use in
the end

Thanks

Mike

Mike,

I don't have any experience with this particular gateway. As long as
they have an open API it shouldn't be that bad to write a ruby
interface. ActiveMerchant is very high quality and is a great place
to get a feel for payment gateway integration. I recently wrote a
plugin that handles subscription billing using TrustCommerce as a
gateway. It might give you a few ideas. The svn repository is at:
http://svn.depixelate.com/plugins/trustcommerce_subscription.

Hope this helps.
