How to extract huge data from postman api or httprequest?

Can anyone suggest how to get Json file as output from postman api for mora than 1lakh data?
I can extract the data for 1-2k lines using httprequest pushing the url,header and body but when the data limit crossed more than 10k the output json is coming null value.
Is there any way to get the whole 10k-1lakh data from postman api or httprequest?

Please help me out.
