Synchronous call in webservice

I have a web service?I want to make it synchronise call how is it possible?What is the process of synchronous and asynchronous call in our system?


Synchronous call is the default. For asynchronous the framework doesn't provide a way of doing it.



Asynchronous and Synchronous are accomodated in BPT (Business Process Technology)  in Outsystems. 

1. A subprocess can run asynchronously by calling Process Extended Action of the subprocess

2. A subprocess can run synchronously by dragging the subprocess to the Flow editor

Also, explore Wait Activity widget, it may satisfy your project requirements.
