My friend you are asking a massive question. Is there an option to integrate? Yes, more than I care to count and they are all documented extensively all over the website. Fttp? Do you mean ftp? I’m thinking no on that one. Depending on your needs you may need a new developer. I think some of the more basic options may have some copy and paste code, essentially, that you can put in an html page. Don’t quote me on that. I know PayPal has something of the sort and I’d say authorize does too.
