I'd like to allow a user to visit one of my sites, enter some information into a field, and then save that information into a Google Spreadsheet via JavaScript.
- I don't want the user to login via Google or have to do any special authentication.
- It's Ok if the spreadsheet needs to be open to public; the data's not sensitive.
- I don't want to use a Google Form, I want to have full control over the client-side UI.
I've been reading through the Google developer docs, but they only make mention to an OAuth login solution. The Google Developer Console allows you to create a "Public API access key", but does not explain how it's used.
