Upon upgrading to version 14720, all of forms that use an API are no longer working with the error message below.

{"response_status":{"status_code":4000,"messages":[{"status_code":4001,"field":"authtoken","type":"failed","message":"Extra parameter(s) not allowed."}],"status":"failed"}}

These were working just fine in version 14600.

Where there any changes causing this? We are using API V3.
