3rd-party account api assuming assumption beyond buyer buys cart charge checkout checkout--just cleanly clears correct difference digial digital double-check download forum google-checkout immediately instantly integration interface interfaced mp3 order over plain posting preparing sale service setting shopping signing sounds steps wanted website

I am preparing to use Google Checkout for my website, which has a digital download (mp3) for sale. I do NOT have a 3rd-party shopping cart interfaced with Checkout--just a plain old Checkout account. If I set that up to charge immediately when someone buys, can your service interface cleanly to provide the digial download instantly (assuming that it clears okay through Checkout)? I'm assuming the answer is yes, but before signing up with you I just wanted to double-check that I do NOT need to have anything beyond the Google Checkout account. Is that a correct assumption?
Thanks for posting over on the Checkout forum, which is how I found out about your service. Sounds like exactly what I'm looking for.

We actually charge the order using API so your setting won't make a difference. Buyer will be able to download the mp3 after the sale.
