In project 9(Sending an SMS when Temperature Crosses Threshold)

Whenever I try to run, I am getting "invalid literal for int() with base 10: “Invalid API key” error!

@ayushsahu99 can you please provide some screenshots that will help me to figure out the problem.
and regarding API key, check if the API key is enabled and if that is already done generate new API paste it in config code and try to run code again.
