Unable to acquire refresh token
Our system already successfully acquires a short lived token, but I want to get a refresh token for Dropbox. We successfully use refresh tokens with systems like SharePoint so are familiar with the flow.
Our app has full access to Dropbox (not just the App Folder) so I am not sure if that is the problem, but we get this error from dropbox when we attempt to get the token:
invalid_request : unknown field "token_access_type"
This is the request that is made
https://api.dropboxapi.com/oauth2/token?client_id=<DropBoxClientId>&client_secret=<DropBoxClientSecret>&redirect_uri=<RedirectURL>&code=<AccessCode>&token_access_type=offline&grant_type=authorization_code
If we call it without token_access_type=offline then it works fine, but we only get a short lived token and no refresh token.
Are refresh tokens only available if you are accessing the App Folder only? Am I not calling it correctly?
Hi Steven_R,
As far as I can see, you are trying authorization by code and mix two different access points calls involved in the auth flow in use - /oauth2/authorize and /oauth2/token. "token_access_type" is valid and usable in the first call, not the second one! 😉 That's where resides your error. On possible results for the second call you can see:
refresh_token String If the token_access_type was set to offline when calling /oauth2/authorize, then response will include a refresh token. This refresh token is long-lived and won't expire automatically. It can be stored and re-used multiple times.
Make a note on meaning for "was" and "when" above. 🙂 Read more carefully documentation.
Hope this helps.

Thanks I have included the parameter at the correct time and it now works.
