Web API set Header Dynamically

How do we set Headers value dynamically on Web API Component?

Our APIs expect Authentication header which changes every 60 seconds, so far we have tried storing the new Authentication Header in Local Storage, but not able to figure out how to add it on Web API component before API Component Call Post method, as the component only offers set URL and Body. Please advise.
