Question

Is it possible to do asynchronous calls in FlexiCapture scripts?

Answer

FlexiCapture scripts do not support threading (and so any asynchronous methods): based on framework specifics, each script can only use 1 thread (as it is just a script, not a full-functional code), and so if you will use any asynchronous methods - it wouldn't be able to create a new thread and will be stopped. So it is not possible to do asynchronous calls in FlexiCapture scripts.
