  • 11. Let’s Build a Web Apphttps://github.com/cmortimore/df12web
  • 12. Let’s Build a Mobile App
  • 13. Token Flow How does it work?1) App Redirects User to Authorization Services where User is Authenticated and Authorizes App2) Token Response returned directly to app on URL behind a # fragment
  • 14. What happens on Mobile?1) Device opens a browser with authorization URL1) Tokens returned on URL behind # fragment – instrumented browser is monitoring and parses URL

  • 19. Notice SSO works! Refresh Tokens It’s a lot like a password  Allows you to get more sessions  Make sure you treat it like one! POST /services/oauth2/token HTTP/1.1 Host: login.salesforce.com Content-Type: application/x-www-form-urlencoded grant_type=refresh_token &refresh_token=5Aep8615VRsd_GrUz3LAcJl &client_id=MyApp &redirect_uri=myapp%3A%2F%2Fcallback
  • 20. Let’s Build an Integration App
  • 21. What if I just want to call server to server Uid / Password Flow - Simple, but uses passwords, API tokens, etc. Web SSO Assertion Flow - Reuse SAML SSO and existing Trust SAML/JWT Assertion Flow - Cert and Trust Specific to the App
  • 22. Let’s Build a Web Apphttps://github.com/cmortimore/df12integration
  • 23. Enterprise Class Authorizationwith Connected Apps
  • 24. Admin Authorization for OAuth Apps1) Admin “installs” app2) App Uses any OAuth Flow3) User Authorization is evaluated via Admin settings
  • 25. Final Thoughts No one likes plumbing….use a toolkit Make your login URLs configurable login.salesforce.com, test.salesforce.com, other Protect against attacks Set a cookie, and check for it on response
