I'm getting the following JSON result when making an API call:

Class Object ( [error] => stdClass Object ( [lang] => en-US [description] => Authentication Error. The table fantasysports.leagues requires a higher security level than is provided, you provided APP but at least USER is expected ) )

I'm just looking for direction on whether this seems to be a problem in how I'm setting up OAuth and my API call or if it's a problem on API Key setup (I set up an application and requested read/write privileges for Fantasy Sports).

Any help would be greatly appreciated!
