Automatic CDR Import from FreePBX

We use a FreePBX system for our customer’s VoIP management. Is there a module, or how easy would it be to setup automatic CDR import on the 1st at 12:01 am every month?
here is link to Splynx API, so any automatic processing module is possible to create.

simple way : Config / Voice / CDR Import
once per month is completely fine.
