When you deploy your app in the sand box mode, you will see your app in the Atlato Store. To redirect into your app, you need to use the following path.Your app should have a /welcome
route which contains a param token
http://localhost:3000 is the Web URL which is under app creation form. You can edit this to any valid url so that you can test it out. This auth token (Access Token + Refresh Token) is not directly the access token, for security reasons it is encoded using the Window: btoa() methodTo get the token to your app from the above example, please use the below decoder functionPlease store this token so that you can use it to authenticate your API calls inside your app.Once your app is in production mode, no need to change anything. Everything works just as in sandbox mode. Make sure your production URL is correct.
