Does Dropbox provides an API for deleting the integration app connection. We just want to allow users to disconnect our Dropbox integration app from our app itself, just like same is allowed from the Dropbox in "Apps" section in 'Personal Account'.
Unfortunately there isn't an API call to completely unlink an API app, but I'll pass this along as a feature request. I can't promise if or when that might be implemented though.
Users can unlink apps via https://www.dropbox.com/account/connected_apps . Apps can revoke specific access tokens/refresh tokens using /2/auth/token/revoke, but not entire apps.
