@RedVelvet2121 The API key is there, but it still throws the error. However, the exact same script works fine with other accounts.

Hi, I was wondering if it would be possible to have the script sending the data to a sheet? Thank you!
I tried to generate something like that but got lots of errors. Guess I'm not so good at it.
