You can only send 1 object as a parameter in the body via post. I would change your Post method to

public void Post(ICollection<Product> products)
{
}

and in your angular code you would pass up a product array in JSON notation

You can also send  POST  multiple params within    and add it   Example    http post config url   api assign-badge     employeeId emp ID bType selectedCat badge selectedBadge        then function response            NotificationService displayNotification  Info    Successfully Assigned    true          function response          where employeeId  bType  Badge Catagory   and badge are three parameters
