How to efficiently transfer bulk upload from an ESP8266 to ThingSpeak?

This link showed me how to successfully do a JSON bulk upload from an ESP8266 to ThingSpeak. I would like to post 60 values in one bulk upload to save on batteries. I know that it is possible to do a CSV bulk upload of data that does not include the "delta_t" or "field1" ascii text for every datapoint as with JSON. This repeated JSON text really bloats the data transfer (about 2000 characters for 60 values). I did successfully complete the Postman example provided in this link but I am unable to mimic this action in the code on my ESP8266. Does anybody know where example code exists - I've been looking for days? Sorry so cryptic but I'm trying to keep my query trim.
