Hi Robert,

Here is the code to read a user extension info and phone number given an access token.

var rcsdk = new RC({
    server: process.env.RC_SERVER,
    appKey: process.env.RC_APP_KEY,
    appSecret: process.env.RC_APP_SECRET
});

var platform = rcsdk.platform();

var data = platform.auth().data();
data.token_type = "bearer"
data.expires_in = your_AccessToken_Expiration
data.access_token = your_AccessToken
data.refresh_token = your_RefreshToken
data.refresh_token_expires_in = your_RefreshToken_Expiraion
platform.auth().setData(data)

platform.get('/account/~/extension/~/')
.then(function(response) {
  var jsonObj =response.json();
  console.log(jsonObj.extensionNumber)
  console.log(jsonObj.name)
  // check API reference for more details
  // And if you want to get the phone number
  platform.get('/account/~/extension/' + jsonObj.id + '/phone-number')
  .then(function(response) {
    console.log(response)
  }).catch(function(e) {
    throw e;
  });
}).catch(function(e) {
  throw e;
});

// And subscribe for notification using pubnub
var subscription = rcsdk.createSubscription()
function subcribeForNotification(){
  var eventFilters = []
  // specify event types you want to get notification
  eventFilters.push('/restapi/v1.0/account/~/extension/~/event_type here')
  subscription.setEventFilters(eventFilters)
  .register()
  .then(function(resp){
    console.log("READY FOR RECEIVING NOTIFICATION")
  })
}
// incoming notification
subscription.on(subscription.events.notification, function(notification){
  ...
})

Hope this helps.
+ Phong
