Dropbox Community ModeratorUnfortunately, I don't have a sample implementation of this endpoint in Objective C to share.
Note that the iOS SDK itself uses OAuth 1, so the stored access token from credentialStoreForUserId can't be directly used as an OAuth 2 access token, which is why you're getting that "Invalid OAuth2 token" error.
If you do want to use that stored OAuth 1 access token, there's a blog post that shows how to implement OAuth 1 here:

(The iOS Core SDK is open source though, so you could alternatively add the source directly and modify the code to add /previews.)
Another option entirely though, which I recommend if your app is still in development mode, is to switch to using the SwiftyDropbox library for API v2, if you can (since it's for Swift):
