This is just a reminder to those who are still utilizing the Google Base API. In about a month, June 1, 2011, the Google Base API will be shut down.

We warned you about this in December, with our post named Google Sunsetting Base API For Two Shopping APIs. As I said then, Replacing the Base API will be two new Shopping APIs, the Content API and Search API.

Google sent out a reminder about this change this week via the Google Merchant Center Help forums. Ronald from Google said:

So if you are still using the Google Base API, you only have a month to start using the other APIs.
