Rapid7 Custom Log Source - Generic API

I’m trying to import the Meraki configuration change log into IDR; the pre-made Meraki event sources do not ingest this data.

So, I’m trying to use the Custom Log Generic API. However, I’m running into an issue in which the event source requires me to define “start_time” and “end_time” parameters in my API query. Meraki’s API doesn’t have these fields; they instead use “timespan”, “t0”, and “t1”. Is there any way I can get around this?
