Communicating our own Raspberry Pi with Farmbot

when you sent us the web app documentation, Did you mean to setup that github file in our own Raspberry Pi to try an communicate with the Web App?

To try and clarify, we are using a second Pi (our Pi) to take pictures of a plant and get data from that plant using a python program in our own Pi. We are trying to send one number to report back on the logs on the Farmbot Wep App data log. We are having trouble sending that number to the FarmBot Web App. We are not very familiar with communication between Raspberry Pi and Websites.

What is the best way for us to send that number from our own Raspberry Pi to the Web App? We hope that explanation can clarify. Thank you
