We're looking to add gift cards to our retail website and I'm wondering how easy or hard it would be to integrate into the site. We're probably going to be using http://ecardsystems.com/, who will provide an API spec. Would this be similar to setting up credit card processing?
All depends on the spec of your site and the integration level of this ecardsystems. If it's just a SOAP or Webservice that you can hit and use it as a pass-through, then it shouldn't be that difficult. Did you build your sites yourself? What Language? DB? etc...
