1. Create your connector

   <gcontacts:config name="google-contacts" clientId="${client.id}" clientSecret="${client.secret}"> <gcontacts:oauth-callback-config domain="localhost" localPort="${http.port}" remotePort="${http.port}"/> </gcontacts:config>

You can get your client ID and secret here: https://code.google.com/apis/console

2. You can then authorize your connector by creating a flow like this:

   <flow name="authorize"> <inbound-endpoint address="http://localhost:${http.port}/authorize"/> <gcontacts:authorize/> </flow>

And browsing to the URL http://localhost:${http.port}/authorize

3. You can invoke your connector like so:

   <flow name="get contacts"> <gcontacts:get-contacts/> <logger level="INFO" message="Contacts: #[payload]"/> </flow>
