Adding a NON PayPal Paid Subscription

[uspacheco]

Hi guys !

I'm back again trying to get some help to set paid subscription for other gateways. For PayPal, everything works perfectly.

But when I try to config other gateways, I do not know what to do. 

My questions are:

1)  I've googled and most of answers for this question says you have to get an API, and I have one.  What do I do next ? Where do I add this API ?  Is there something with   Simple Scripts at my host ?

2) Is it possible to have 2 bottoms options to make an ORDER ( one for PayPal and another one for another payment service ) ?

Thank you in advance !
