Hey! would you be able to help me? I'm trying to set up a discord bot that gathers all changes from my company's google sheets and sends appropriate notifications.
seems that I need to get that information https://developers.google.com/sheets/api/reference/rest/v4/UpdateValuesResponse but i'm not so sure how to connect it. What do you think?
