This means that new API key requests will no longer be issued. In order to request re-issuance of an already existing API key, please contact our HelpDesk by visiting
https://help.change.org.
In addition, we would like to let you know that Change.org will be eventually discontinuing the API in this version of implementation, since we have found the security risks to be too high; this is, however, unlikely to happen before 2018.
