I have an Asp.Net Core Minimal API web app. I want to version an endpoint using request header X-Api-Version. Depending on the version I want to do different things. Something like this:

app.MapPost("/save", (
    [FromHeader(Name = "X-Api-Version")] SaveVersion version,  // how to constraint this to v1?
    [FromBody] SaveRequestV1 request
    ) => "Do something");

app.MapPost("/save", (     // this is considered duplicate route
    [FromHeader(Name = "X-Api-Version")] SaveVersion version,
    [FromBody] SaveRequestV2 request
    ) => "Do another thing");

public enum SaveVersion
{
    v1 = 1,
    v2
};

public class SaveRequestV1
{
    public string Name { get; set; }
    public bool IsMember { get; set; }
}

public class SaveRequestV2
{
    public string Name { get; set; }
    public int MemberStatus { get; set; }
}

Is it possible to have different route handlers based on request header?

Can Swagger understand this versioning by request header?
