Performing the OAuth Dance with an OAuth-Enabled Module

The final step for using the module is to trigger the OAuth dance. Configuring an OAuth-Enabled Module includes a parameter called authorizePath through which the end user configures the path of an automatically created HTTP endpoint that is needed to hit a browser and start the OAuth dance.

Tip: Remember that the Authorization Code grant type that the SDK supports requires human interaction through a web browser.

Multi-Tenancy

Multi-Tenancy for OAuth means being able to perform the OAuth dance multiple times and to associate each obtained token with a different resource owner ID.

The end user needs to specify the resourceOwnerId to assign to the token when the dance is initiated. For example, if authorizePath is set to /authorize, and you want to perform a dance for the user sdk_demo, you should hit the following HTTP path: /authorize?resourceOwnerId=sdk_demo.

After the dance is complete, you execute an operation using the access token obtained for that user. You do that by using an expression on the resourceOwnerId parameter of your module’s configuration. Here is a complete example:

<sfdc:config name="salesforce">
    <sfdc:oauth-connection display="PAGE" immediate="FALSE" prompt="CONSENT">
        <sfdc:oauth-authorization-code consumerKey="${sfdc.consumerkey}" consumerSecret="${sfdc.consumersecret}"
                                       authorizationUrl="http://..." accessTokenUrl="http://..."/
                                       localAuthorizationUrl="http://localhost:8080/.." scope="this that and those"
                                       resourceOwnerId="#[vars.ownerId]" /> <!-- <1> -->
        <sfdc:oauth-callback-config listenerConfig="myHtttpListener"
                                    callbackPath="/callback"
                                    authorizePath="/authorize" />  <!-- <2> -->
</sfdc:config>
1 The resourceOwnerId parameter is set to an expression. Each time an OAuth-protected operation is executed, that expression will be evaluated, and the token associated with that value will be used.
2 The example sets the authorization endpoint authorizePath.

Invalidating Access Tokens

Multi-tenancy implies the ability to invalidate the access token of a particular resourceOwnerId. Invalidating the token causes the associated token information to be deleted.

To invalidate an access token, the SDK automatically adds an operation called unauthorize to every OAuth-enabled module. Returning to the example above, you might invalidate the obtained token with any of the following statements:


          
       
1
2
3
<sfdc:unauthorize resourceOwnerId="sdk_demo" config-ref="salesforce"/>
<!-- or -->
<sfdc:unauthorize resourceOwnerId="#[vars.resourceOwnerId]" config-ref="salesforce" />
