code? a google checkout api xml (url/delivery)? and implimentation of? callback url for my site, so that the clients checkout experience works using just a simple"buy now" button....no shopping cart on site.
## Deliverables
basically? the google "buy now" button on my site to be able communicate the digital download link on the "thank you" page that google supplies after the credit card authorization.
write a custom notification (url/delivery) xml api using server to server method communicating with google checkout? and a pessimistic display disposition.? so users will be presented with an embedded download key after authorization for a digital content download.
may need to instruct for implimentation(so it works)? to where to upload xml file.. and maybe instructions for download page? (callback url ....shttp?)for said? digital content. may need other xml files..unsure. google merchant page does the rest.
