The Blogger API has been added to Tabulas; this will allow you to update your Tabulas accounts with programs like w.bloggar and Performancing (Firefox plugin).

The Blogger API endpoint is: http://api.tabulas.com/blogger/

If you are using the old Blogger API endpoint, please discontinue your usage of that endpoint and please start pointing to this new one. I will phase out the old Blogger API endpoint at the end of February.
