Powershell Oauth2 Refresh Token
Hey all! Thanks in advanced. I am trying to write a powershell script to get an offline refresh token so I can do unattended uploads. The problem is that I have to authenticate for an author...
I'm not sure what you mean when you say you are "not getting any type of response from the curl command". For reference, if you need to debug something with curl, you can use the "-v" flag to enable verbose mode.
In any case, I haven't tested your new code, but the parameters look right. I also don't see where you retrieve the access token from the new /oauth2/token call, but assuming you do either manually or in code not shown, it seems right. Does it work for you when you run it?

Dropbox StaffIt is not possible to fully automate the OAuth process where the user chooses to authorize the app and the app then receives the resulting access token and optional refresh token. This needs to be done manually by the user at least once.
If your app needs to maintain long-term access without the user manually re-authorizing it repeatedly, the app should request "offline" access so that it gets a refresh token. The refresh token doesn't expire and can be stored and used repeatedly to get new short-lived access tokens whenever needed, without the user manually reauthorizing the app.
You can find more information in the OAuth Guide and authorization documentation. There's a basic outline of processing this flow in this blog post which may serve as a useful example of how to use a refresh token to maintain long-term unattended access.
Thanks for the reply Greg -
The script above does request offline access. If you see line 10, the authentication url has "token_access_type=offline".
I get the refresh token once, and I plug it in, but it doesn't last more than a couple of hours before it expires.
