Pro tips
redirect_uri_mismatcherrors mean the URIs (https://auth.appdocumentation.com/app/oauth2/callbackandhttps://auth.appdocumentation.com/) do not exactly match what’s in Google’s settings.If the consent screen still shows the old domain, re-check app status if verified or not from Google Cloud Account.
