I'm trying to use the REST API from within an Objective C mac app but keep getting this "redirect_uri_missing" error, even though the parameter IS specified in both the URL I'm opening with the browser for authentication as well as in the app's configuration in the developer console.
The error details even mention this redirect_uri parameter, for example:
Whatever I enter there – using custom url scheme or http:://localhost, either with a fixed or dynamic port, I keep getting this error and thus can't get OAuth to work. Am I missing something essential here? It's pretty frustrating...
