Why are you posting an XML body to delete an album? This is probably what's causing the 501.
Don't create and send your xmlBuffer in the request. Just send the required headers to the proper album edit URL. Also, the URL you're sending this to is wrong. You have to use an album edit URL. You can read up on deleting albums again here: http://code.google.com/apis/picasaweb/docs/2.0/developers_guide_protocol.html#DeleteAlbums Example: POST /data/entry/api/user/<user_id>/albumid/<some_album_id> HTTP/1.1 X-HTTP-Method-Override: DELETE GData-Version: 2 Authorization: GoogleLogin auth=<some_auth_key> If-Match: * On a side note: Why don't you just use the JAVA client library for interacting with the service?
