Which url should be use to get Data and oAuthintication using REST API?

Hi Expert ,
i am following url (https://developer.infusionsoft.com/getting-started-oauth-keys/) for oAuth .1st and 2nd step is done .Now i am confuse in 3rd and 4th step . I will create one sandbox account.
3rd Step : In reference document Request Permission url is ‘https://signin.infusionsoft.com/app/oauth/authorize’ . Is this url will be same for my Sandbox Account .
In reference document Request an Access Token url is ‘https://api.infusionsoft.com/token’ . Is this url will be same for my Sandbox Account .

  4th Step : In reference document Refresh an Access Token url is 'https://api.infusionsoft.com/token' . Is this url will be same for my Sandbox Account .

In API reference document API url is  'https://api.infusionsoft.com/crm/rest/v1'  . What will be base url for me if my Sandbox url is 'https://surajitstore/crm.com' .

 I am confused where should i used my sandbox account url.
