I have never used a payment gateway before. I want to use PHP to include CCAvenue into my website. I downloaded their integration kit, added my merchant id and functioning key, activated the account, and attempted to complete a dummy transaction on the index file they provided in my localhost. However, the form submits button sends me to the CCAvenue Transaction error page without providing an error code or description.
Tell me where I'm doing wrong and what else I should be doing. If somebody could direct me to a tutorial other than the CCAvenue integration handbook, that would be excellent.
