How to post HTTP request with Arduino + ESP8266 AT commands

Question

In order to send data to google spreadsheet I need to request HTTP access to the unique URL, something like this:

https://script.google.com/macros/s/AKfycbz7jkkd7nfa6ThjOqGw5KZgnUUxIOrxCV_m8WithLQD4EAS7hx6/exec?SOMEDATEHERE

I tried with:

GET https://script.google.com/macros/s/AKfycbz7jkkd7nfa6ThjOqGw5KZgnUUxIOrxCV_m8WithLQD4EAS7hx6/exec?SOMEDATEHERE HTTP/1.0,

but with no success.

Any idea how to execute this HTTP request with AT Commands?

This is the whole process, and even I get "SEND OK" as a result, but no new data appears in Google Spreadsheet: link — Branislav Vajagic

I only get SEND OK and nothing else. If I wait for to long I get disconnected. — Branislav Vajagic

I manage to do it.

First of all I wasn't able to make it work with Arduino IDE Serial Monitor because of Carriage Return and New Line characters so I switched to RealTerm. In it I manually write "\r\n" after every AT command. New i connected Googles Spreadsheet link with Pushingbox (as shown in this video). After that I used next AT commands:

// Only after Restarting module
//-----------------------------
AT+CIPMODE=0\r\n

AT+CIPMUX=1\r\n
//-----------------------------

AT+CIPSTART=4,"TCP","api.pushingbox.com",80\r\n

AT+CIPSEND=4,89\r\n

GET /pushingbox?devid=<DevID>&<field>=<value> HTTP/1.1\r\nHost: api.pushingbox.com\r\n\r\n

Thanks for help.

Dude thank you so much for leaving this notes! The \r\n and HOST at the end definitely worked lol
