Is anything changing with the FeedBurner APIs?
Yes. There are three changes with APIs that are important to follow. First, for authenticated APIs, you must now use either ClientLogin or AuthSub with a valid Google account for authentication. Second, for the Awareness API, the new endpoint for Awareness API requests will be at https://feedburner.google.com/api. Note that this is only available via HTTPs on port 443. Finally, as previously announced, we will no longer be supporting or providing the Management API, except to previously contracted customers. We are in the process of updating these APIs to be current with the features we provide, documenting the API better so that publishers can be self-sufficient, and making sure the APIs are secure and cannot be abused. We are also looking at how to best support bulk management of feeds through our UIs and APIs in a future release.
