Today's converted Leads

Hi,

I am working on a application with different zoho account where we have more than 1 Million leads. The team follows the leads using our custom application (all leads are mirrored) and convert the leads in zoho CRM.

I want to update the status of the converted leads in website database on the daily basis using API calls /webhooks.

I know there is custom view to see the converted leads and I can use it in API. But it will not be possible to fetch the all converted leads everyday and update the status in database. I cannot do it because of the restrictions of the ZOHO CRM in number of API calls every day and the huge amount of the records. I am already running short of getCVRecords API Calls to perform the various operations.

Please suggest how I can see the today's converted leads using the API.

Your prompt reply will be appreciable

Thanks
Sanjay
