So what does this error actually means? Well, the redirect URI that you have set up should be in line with the detail that you are entering during the authentication process. Even a slight mismatch between the URI that you input during the initial setup phase and the one that you are typing in the OAuth process will straightaway result in the redirect_uri_mismatch error.
