Web Data connector in WPF C# -

i in need develop application used access(get data from) web accessible resources twitter,facebook,linkedin,salesforce etc. using appropriate rest api's. can please suggest me pattern , architecture design logic of application?

since coupling many online providers, there's increased chance api implementation changes overtime.

1. think api services other datasource. implement api service requester provider class. create abstraction between provider , actual process (where use data once it). provider act source of data rest of application. changes api service not affect whole application.
2. create separate provider classes each online platform need. create model represents data api services , pass model object between providers , consumers.

something this

public interface ifbconnect {     public fbdata getfbdata();     public bool postfbdata();     //etc. etc }  public class facebookprovider : ifbconnect {     public fbdata getfbdata() {         //call webservice         //parse json model object         return fbdata     } }
