Re: Can clients count on blogUserInfos.userId having a "g" prefix?

Hi Daniel,

I checked in with our engineering team, and the word is as follows. The
user ID provided by Blogger is not the ID the user needs for Picasa.
The best is to obtain the user ID directly from Picasa:

   - first call https://picasaweb.google.com/data/feed/api/user/{email
   address} and extract the user ID returned
   - then call
   https://picasaweb.google.com/data/feed/api/user/{picasaUserID}/albumid/{bloggerAlbumKey}

hth,

brett
