I think I see where the confusion is coming from now, @teja gudipati .
So the token comes in the body of the response, and needs to be placed into the header of the next request, if I understand correctly.
In this case, "AbsoluteURL" is not what you want to use.
The Key should be Headers['header_name_for_next_page_token']
, renames as appropriate.
The Value should be $.nextPageToken
The Key specifies where to insert pagination in the next request.
The Value specifies where to get the pagination info from the response.
