Pagination and Date Filter is Not Working in Zoho CRM V2 API

We are trying to get leads from our Zoho CRM using API version 2.

We only need to get the last modified leads from our system. According to your documentation we have passed the parameters to request as follows

We have to get the records which are updated/created on or after 2019-11-04T00:00:00+00:00 means after 12 AM on 4th Nov to 5th Nov 12 am.

In our CRM there is last records which are updated/created on 24th October. After that no data is modifed and created still the response is showing all the leads from CRM.

Also we only able to retrieve the records on first page. We have data on 2nd page but when we use the page parameter then it always returning the same records which are on page1

We need to get correct result from API .

How can we do this?
