We are preparing to roll out our implementation of encrypted user id’s announced in late December: Protecting Myspace User IDs
This will affect ALL IFRAME based applications.
The two easiest solutions are to either grab the Opensocial token from the IFRAME URL and make a call to: http://api.myspace.com/1.0/people/@me/@self?opensocial_token= or the decryption method outlined in the previous blog post: Protecting Myspace User IDs
This will be permanently enabled in 30 days. Please have your code adjusted no later than Monday, April 18th, 2011.
