is there a way to integrate a form with Google Checkout? For example, I have a form in which the customer would customize products. I would like to tie it in with Google cart so that at the end of the form they can "add to cart" and later checkout. Is this possible?
Sorry, we do not support Google Checkout at this time, but you can do this with PayPal. More info here: http://app.formassembly.com/connector_paypal/documentation/connector_setup#introduction
Actually, that may not work for me... is there a way to do this without upgrading? I actually need to be able to add an "add to cart" button, not just a straight checkout button. Or, is it possible to alter the paypal button html in order to encorporate the price/ color/ etc. from the form?
Sorry but I don't think it's going to work. We don't support the 'add to cart' button, so any solution based on FormAssembly would require some custom coding of some sort.
I'd recommend you take a look at some of our competitors, perhaps wufoo.com or formstack.com.
