I'm trying to convert:
http://www.zen-cart.com/downloads.php?do=file&id=921

to 1.5.0 and I'm really struggling, any one have any suggestions?
or can give me an idea what changed as far a credit card processing in 1.5.0?
or know of another mod that works with 1.5.0 for direct post api?

Here is a link to the direct post api.

any thoughts?

Thank you in advance!
