API Monitor with Auth based on Login via Form Post

Team,  I have some APIs I need to monitor that are not using OAUTH2 or typical headers.  These are APIs that are hosted by an .NET Site and the authentication is based on end user that is logged into the site.   Which is very typical for APIs exposed via Razor or MVC Site.  I am able to login via Insomnia posting the login information, but to get to this point it is multiple steps.  

1. Can this type of auth flow be done in AlertSite?
2. If I use DejaClick to script the login. Can that script be modified to make an API call?

Thank you
