Example code

// Step 2 - Define a configuration object. Insert your API Key below: 
var conf:Object = { 
    APIKey: 'Put Your APIKey here', 
    mcRoot: root, 
    enabledProviders: '*' 
} 
 
// Step 3 - Load Social service 
// 3.1 Create the load-parameters object 
var loadParams:Object = { 
    services:'socialize', 
    callback:onServiceLoad

// 3.1 Load the services

     // Step 5 - Calling the Social API method - connect:
