Materials http://lanyrd.com/sryxw

OAuth 2.0

OAuth 2.0 Authorization for RESTful APIs Evolution of Google AuthSub, Yahoo BBAuth, AOL OpenAuth etc „Valet key‟ for the web Emphasis on simplicity, ease of implementation

OAuth Roles

OAuth 2.0 ProtocolAuthorization Resource Server Browser Client App Server GET /something 302 Found Location: https://login.ex.com/?response_t ype=code&client_id=…&redirect GET /?response_type=... _uri=…&scope=… Authenticate 302 Found Location: https://app.cl.com?code=… GET /app.cl.com?code=… POST /token code=…&grant_type=authorization_code&client_id=…&client_secre t=…&redirect_uri=… 200 OK { “access_token”: “00D5…”} GET /data Authorization: Bearer 00D5… 200 OK 200 OK Data Some Content

Force.com Identity Service OAuth response contains „id‟ element:{ "access_token": "00D5...”,"id": "https://login.salesforce.com/id/00D50000000IZ3ZEAW/005 50000001fg5OAAQ", "instance_url": "https://na1.salesforce.com", "issued_at": "1308806720993", "signature": "GhBp..."} We can access this URL (with the OAuth token) to obtain information on the user Same pattern as OpenID Connect

Social Sign-On

CRM processes have historically been disconnected

The Social Enterprisecommunicates in new ways…

…but how do social customers and partners directly engage with your products and services?

IntroducingSocial Sign-On

Social Sign-On – Automatically create and update users and contacts – Single Sign-On makes it easy and keeps them coming back – Deliver applications and services to deepen your relationship – Active engagement automatically updates your customer data

So what’s under the covers? The Auth Providers Framework – Pre-integrated Single Sign-On from branded Identity Services – Automatically create and update Contacts and Users – Full control over data modeling with Apex Registration Handlers – Works for both internal and external users Out of the box support – Facebook: B2C – Salesforce: B2B – JanRain: Breadth & Depth support for a wide catalog of Identity Providers

When to use Auth Providers Business to Consumer – Use Facebook or JanRain for more options Business to Partner – Use Login with Salesforce for collaborating with Partners or Customers that have existing Salesforce deployments – Use SAML for point to point federations Business to Employee – SAML is still the preferred option ( see roadmap ) – SAML provides static

Exercise 1

Exercise 1: Configure an Auth Provider Create a Force.com Developer Edition environment Create a Customer Portal Create a Force.com Site, and link it to the portal Create a Facebook App Create an Authentication Provider Create a login page for the portal Login to the portal from Facebook

The Facebook Graph API

The Facebook Graph API https://developers.facebook.com/docs/reference/api/

Accessing Social Graph Objects Every social graph object has a unique ID – https://graph.facebook.com/ID For example, Facebook Platform has ID 19292868552 – GET https://graph.facebook.com/19292868552

Relationships – Edges on the Graph Friends, feed (wall), likes, photos, videos, etc Graph API terminology: connections – https://graph.facebook.com/ID/CONNECTION_TYPE For example, my friends – Special ID - me – GET https://graph.facebook.com/me/friends

Graph API Authorization OAuth 2.0 – Obtain access token representing user‟s permission to access their social graph – Supply it with Graph API calls as a query parameter • https://graph.facebook.com/ID?access_token=TOKENVALUE Access to specific types of graph objects is controlled by permissions – user_likes, friends_photos, publish_stream etc – Requested via OAuth 2.0 scope – Balance app functionality against intrusiveness

Searching Search via https://graph.facebook.com/search GET https://graph.facebook.com/search?q=force.com&type= post&access_token=AAA

Publishing HTTP POST to a connection URL – Access token is required! – curl -F access_token=... -F message=Hello world! https://graph.facebook.com/me/feed – Response: {"id":"667905711_10151088147280712"}

Graph API Explorer https://developers.facebook.com/tools/explorer

The Force.comToolkit for Facebook

Sidebar: Writing Apps for Force.com Platform-as-a-Service – Apps run on the Salesforce infrastructure Model-View-Controller architecture – Model = database.com – View = Visualforce – Controller = Apex Force.com Workbook is a great place to start – http://developer.force.com/workbook

Force.com Toolkit for Facebook Apex binding for the Facebook Graph API Map<String,String>params = new Map<string,string>{fields => id,name, limit => 10}; FacebookUsersfriendsList = new FacebookUsers(access_token, me/friends, params); for (FacebookUseru : friendsList.data) { System.debug(u.name); } Graph API objects modeled as Apex classes – FacebookUser, FacebookPhotoetc Open source, but unsupported

Exercise 2

Exercise 2: Create a Social Application Add a Visualforce page to the portal Retrieve the user‟s friends list Expand the requested scope Retrieve the user‟s photos Think – what could I do next?

Roadmap

Roadmap for Auth Providers StartURLs and Custom Scopes – Pilot during Summer 12 timeframe Communities, Site.com, and Orgs – Authentication for Collaboration, Marketing, and multi-org single sign-on Make it great for employees – Tie into My Domains so it works just like SAML
