Payment Method

[IceMan-101]

Hi All,

I am looking for a way to create a payment method that reads the "User's" available credits from a web service (API) and if the user has the correct amount of credits available, it will deduct the credits via the API and process the order and if the user does not have the correct amount it will return an error to the user and decline the order.

I could always do this via VM 1.1, but in VM 2.0.2 the whole payment method changed and I did search for documentation and tutorials on how to do this by writing a new payment plugin for my VM store, but I got no good results and I am currently lost... 

Any help in the regard would be a appreciated.

Thanks,
