connect the Tx pin of esp8266 to the Rx pin of arduino and the Rx pin of esp8266 to Tx pin of arduino

Have you considered using the library here: https://github.com/mathworks/thingspeak-arduino
My recommendation is to start from the examples that are part of the library. For example here: https://github.com/mathworks/thingspeak-arduino/tree/master/examples/ESP8266

I Had the same problem and I tried the github stuff and it still didn't work.

22:55:26.930 -> 0. at command => AT+CIPMUX=1 Fail
22:55:31.955 -> 0. at command => AT+CIPSTART=0,"TCP","api.thingspeak.com",80 Fail
22:55:47.064 -> 0. at command => AT+CIPSEND=0,60 Fail
22:55:52.566 -> 1. at command => AT+CIPCLOSE=0 Fail
Why there is no data in thingspeak?
