I spent a lot of time coding a good checkout solution that worked with Google Checkout, so I was pretty mad when all the work I did went down the drain when they discontinued it. I was fortunate to had already integrated Paypal and Amazon checkout before it was discontinued, so the business impact was pretty small.

But this also shows an interesting trend away from APIs and "Mashups." 5 to 10 years ago, providing an API for your startup was considered an essential way to promote your platform by having it integrated all over the place. I suspect too many developers got burned in the way that I was with Google Checkout, and stopped trying to "mashup" APIs to the point where there was no longer much benefit to provide them.
