Google Assisted Relay board control

Hi, i have esp8266 board with 2 relays and microprocessor, everything is working fine when i am using phone app (turn on/off relays) in STA and AP mode, but how to turn on/off relays over IFTTT or Google Assistant? I found this code on internet but the only thing I made it is to swtich on/off led on ESP-01, but relays remained silent…i was working over adafruit.io

link for esp8266 board with 2relays is:

on board there are 2 jumpers in positions RX-RX1 and TX-TX1

code is here(its code for 4 relays but never mind, i was trying to turn relays on/off
