Can anyone please help to understand whether it’s possible in FD to search(filterTickets) based on created date range like from date and to date.
Yes, there is an option to filter tickets between two dates. Please explore here to know more about this.
Adding on to @Saravanakumar_Raju answer, a sample search query might look like this
https://example.freshdesk.com/api/v2/search/tickets?query="created_at:>'2020-05-30' AND created_at:<'2020-06-01'"
More examples can be found in the example section of the link that @Saravanakumar_Raju has shared.
