ESP32 subscribes to a ThingSpeak channel.

App on your phone sends API command to the ThingSpeak channel.

have any tutorial or video showing how this is done? I am having trouble finding it, I speak Portuguese I am researching in English because there are more things, but it is more difficult for me, I even write this using the translator if there is something wrong, sorry

I don't have a specific one that I know about. This video on connecting the ESP32 to ThingSpeak might help: https://www.youtube.com/watch?v=F1fQ8m3S8-4
