Later this week we will be adding a new error code to the API: error code 86, Account_Blocked. This error code indicates that the account you are trying to access has been blocked due to suspicious activity.
We are in the process of adding this new information to the Developer Guide. In the meantime, if you would like to learn more about account blocking and error code 86, please refer to the FAQ entry "What is Error Code 86 (Account_Blocked)?".
Please note, there have been no changes made to the WSDL as a result of this addition.
