The 4th of November, the old export interface will be discontinued and shut down, in favor of the new HTTP API. 

Please, change your scripts, cronjobs, etc, to comply with the HTTP API as soon as possible and before the 4th of November, when export.py will not be available anymore.

More information about the new API and how to use can be found here:

Best regards,
Indico team
