I am trying to get account credentials for my Google account which can be stored in a command line file. The script expects these 3 parameters to be set.
local client_id = ""
local client_secret = ""
local refresh_token = ""
So I expect I need some kind of OAuth token which will never be invalidated.
Does anyone know how to acquire it?
You get the client id and the client secret from the Google dev console. You get the refresh token by doing a one-time authorization.
All of the steps are detailed in this answer How do I authorise an app (web or installed) without user intervention? (canonical ?)
Be very careful about how you secure the refresh token. It acts like a username/password for your Drive account, so could be used by "bad dudes". It's a good idea to use the most restrictive scope (step 8 in the above list). drive.file is a good choice if your script is uploading. If your script needs to download files, try drive.readonly.
