correct way to use a provider template in controller/service

I have successfully connected via connect controller to service provider. In another controller I want to access the API. Can i inject the ProviderTemplate class and use it? What is the proper way to now consume this API? I have been digging through the docs but its not clear to me.

so for example in my service I want to:

@Autorwired:
private FacebookTemplate fbTemplate;

@RequestMethod(value={},RequestMethod.GET){
public String doSomethingWithAPI(){
return fbTemplate.likeOperations.doSomething;
}
}
Thanks,
Barry
