I am digging into the Workflow Cloud to see how can we use it as the workflow as a service for a custom application hosted in the cloud, I know we can start the workflow by calling the REST API, but how can I get the workflow wait or pause until another call came in? This feature exist in other products, but I want to see how to accomplish it by Nintex.
Is it my a sub-workflow like the utility workflows? or is there something else?
I need something like wait for a task to be completed, and I want to complete the task remotely. And I don't want to put a Call REST action in a loop and execute it every few minutes to check.
