c# - Should I use IEnumerable or List for parameters from WebApi?

Let's say that I have

[HttpPost("some/route")]
public void AddSomething([FromBody] QueryParameter parameter){
    DoSomething();
}

and my parameter is:

public class QueryParameter  {

   public int ElementId { get; set; }
   public IEnumerable YearIds{ get; set; }       
}

The question is: can I keep IEnumerable or it should be List?
What is better practice and why?
