What is the best way to encapsulate multiple service calls using Spring?

I need to call one third party service and if it succeeds, then i will call another service of my application. What is the best approach to encapsulate this calls? and ensure that its become a single transaction?

For Example, call this services in one single point:

public class ThirdPartyService(){

    sendProduct(){
        // Call external service
    }

}

public class ProductService(){

    confirmProduct(){
        // Do stuff
    }

}
