Migrating oauth1 to oauth2 using token_from_oauth1
I have been using Dropbox via the Sharpbox toolkit for a while. It's based on oAuth1, so I have a database full of oAuth1 access tokens for my users.
I'd like to convert to the new Dropbox API, which is based on oAuth2. I see that there is a "token_from_oauth1" endpoint in Dropbox's v1 spec, but I'm not figuring out how to successfully connect to this endpoint to upgrade a user's existing token. (I'm using C#/.NET).
Can anybody point me to some sample code that shows how to create a properly authenticated call to perform this operation?
Thanks

This call needs to be signed using OAuth 1, so this blog post, specifically step 4, maybe be helpful:
https://blogs.dropbox.com/developers/2012/07/using-oauth-1-0-with-the-plaintext-signature-method/
In short, you need to supply all of the parameters shown there. (It's also possible to send them in URL parameters.)
The actual spec is here if you want:
here's a library for Twitter oAuth 1.0 (see http://www.voiceoftech.com/swhitley/?p=681) that actually makes it easy to make oAuth 1.0 authenticated calls. So the code below seems to work pretty well for me:
oAuthTwitter oat = new oAuthTwitter();
oat.Token = <oauth 1.0 token>;
oat.TokenSecret = <oauth 1.0 secret>;
oat.ConsumerKey = <application key>;
oat.ConsumerSecret = <application secret>;
string resultJSON = oat.oAuthWebRequest(oAuthTwitter.Method.POST, "https://api.dropboxapi.com/1/oauth2/token_from_oauth1", null);
