title: how to setup the redirect url for Slack?
body: <p>I have created a slack app and stuck at adding the redirect url. I want information like token, team_id from redirect url. I went through the link <a href="https://api.slack.com/authentication/oauth-v2" rel="nofollow noreferrer">https://api.slack.com/authentication/oauth-v2</a> I got the idea of redirect url, but how should I create although I used client_id,secret in the url but I want to capture the HTTP request response. How should I create one?</p>
