I've made no code changes all to the Google Sheets integration I have in my Chrome extension (internal use only in our company). Today, I'm getting a '403' error with the message "The request is missing a valid API key."
I am not using an API key and never have - just a Client ID. This has been great for years, up until today or yesterday.
My scopes are https://www.googleapis.com/auth/spreadsheets and https://www.googleapis.com/auth/userinfo.profile.
Any thoughts? Did something change here that I'm not aware of? I did see this: https://github.com/zquestz/omniauth-google-oauth2/issues/106 but the time frame doesn't jive with what I'm seeing.
