Deep Dive into OAuth for Connected Apps Hargobind Singh Senior Manager hargobind.singh@capgemini.com @hargobindsingh Hargobind Singh Senior Manager, Capgemini About oAuth Implementation Scenarios Demo Wrap Up Overview About oAuth The OAuth specification defines a delegation protocol that is useful for conveying authorization decisions across a network of web-enabled applications and APIs Benefits : - Security - Maintenance - Ease of Use Why OAuth ? App Access App Authenticate Authorize OAuth allows aclientapplication restricted access to your data at aresource servervia tokens issued by anauthorization serverin response to yourauthorization. Token Types: Authorization Code short-lived token created by the authorization server and passed to the client application via the browser. Access Token The access token is used by the client to make authenticated requests on behalf of the end user. Refresh Token The refresh token may have an indefinite lifetime oAuth Implementation Scenarios Web Server Flow Most web apps would use a web-server flow to obtain a token on behalf of the end-user Authenticate, Authorize Client Parameter Description response_type Must be set to code to request an authorization code. client_id Your application's client identifier (consumer key in Connected App Detail). redirect_uri The end user's browser will be redirected to this URI with the authorization code. This must match your application's configured callback URL. Token Response Parameter Description code The value returned by the authorization server in the previous step. grant_type Set this to authorization_code. client_id Your application's client identifier. client_secret Your application's client secret (consumer secret in the connected app detail page). redirect_uri Again, this must match your application's configuration. Web Server Flow: Response Parameter Description id A URL, representing the authenticated user, which can be used to access the Identity Service. instance_url Identifies the Salesforce instance refresh_token A long-lived token that may be used to obtain a fresh access token access_token The short-lived access token. Web Server Flow - Response Sample Response User Agent Flow The user agent flow allows client applications running on users browser to obtain an access token Request Token Parameter Description response_type Value can be token, or token id_token with the scope parameter openid and a nonce parameter client_id Your application's client identifier (consumer key in Connected App Detail). redirect_uri The end user's browser will be redirected to this URI with the authorization code. This must match your application's configured callback URL. User Agent Flow: Response Parameter Description id A URL, representing the authenticated user, which can be used to access the Identity Service. instance_url Identifies the Salesforce instance refresh_token A long-lived token that may be used to obtain a fresh access token access_token The short-lived access token. Token Refresh Once the lifetime of a token expires, the client application can use the refresh token to obtain a new access token Request Token Parameter Description grant_type Set this to refresh_token. client_id Your application's client identifier. client_secret Your application's client secret (optional). refresh_token The refresh token provided in the previous authorization. Token Refresh: Response Parameter Description id A URL, representing the authenticated user, which can be used to access the Identity Service. instance_url Identifies the Salesforce instance refresh_token A long-lived token that may be used to obtain a fresh access token access_token The short-lived access token.
