I really liked this video it had a lot of theory but also I like that you added the practical side of things and was really good to see how things are build and run.
Great video, learned a lot, I have a small question because I get confused on the way variables are used, I don't see that the variable names you wrote from the message request have the same name as the variable names of the data request, how does the system know what vale to pass into each one?
