SAP PI REST Polling scenario

PI REST Adapter - Polling a REST API

We would like to frequently poll hiring information from REST API

We have two options in REST Adapter polling in SAP PO:

Option 1: Incremental request based on timestamp of last call

Option 2: Incremental request based on response content

Can we combine these two options

Is there any custom way of handling below HTTP polling scenario. I am trying to get candidates from a Recruiting system and I need to pass below values in URL:

https://api.jv.com/api/v2/candidate?api=<key>&sc=<secret>&format=json &start=1&count=50&datestart=2016-04-25&dateend=2016-04-26

1. So my variables are "start" which would the next starting index i.e. 1...51...101

2. datestart would be the last time I ran this interface

3. dateend would be current time.

I tried the incremental count approach but how do we handle both incremental date and nextPageToken ?

Also if I use next Pagetoken the API response doesn't carry a page index or current page and next page token.

  If we are iterating the records page by page, say we have 2000 records and max we can get in one request is 500, the 4 request call will be as below:
  
  https://api.jv.com/api/v2/candidate?api=api_key&sc=abc&start=1&count=500&datestart=2016-04-25&dateend=2016-04-26
  
  https://api.jv.com/api/v2/candidate?api=api_key&sc=abc&start=501&count=500&datestart=2016-04-25&dateend=2016-04-26
  
  https://api.jv.com/api/v2/candidate?api=api_key&sc=abc&start=1001&count=500&datestart=2016-04-25&dateend=2016-04-26
  
  https://api.jv.com/api/v2/candidate?api=api_key&sc=abc&start=1501&count=500&datestart=2016-04-25&dateend=2016-04-26
  
  What value do we store in nextPageToken and how do we handle the date start and date end ?
