1. Leave min_id empty for first request then provide next_min_id received from previous request to get more items.
2. Suppose next_min_id received from respone is
   next_min_id:"{“cached_comments_cursor”: “18258335668144379”, “bifilter_token”: “KGMBEgDQADAAGAAYABAACAAIAAgACAD__r_Xt9__399-v-P93__v95nP_ff___9-w0X36stPQPI7s39Mr_ZHrvf_317o27L9__P__-Xff__3_fP___9-vvUeG8CTcCu4gAgA”}"
3. Inside min_id parameter put next_min_id value as it is ex.
   min_id={“cached_comments_cursor”: “18258335668144379”, “bifilter_token”: “KGMBEgDQADAAGAAYABAACAAIAAgACAD__r_Xt9__399-v-P93__v95nP_ff___9-w0X36stPQPI7s39Mr_ZHrvf_317o27L9__P__-Xff__3_fP___9-vvUeG8CTcCu4gAgA”}

So you just need to copy next_min_id value and paste in min_id parameter.
