Validate json request body to prevent parameter tampering in .NET Core Web API

I have a .NET Core 3.1 Web API and have multiple controllers and actions. I am using some models in my actions to receive data from request payload (as JSON). I need to verify each JSON input parameter keys with the model in order to prevent parameter tampering.

[HttpPost]
public JsonResult GetData(SelectnObject obj)
{               
    return Ok(JsonConvert.SerializeObject(output));
}

My model is like

public class SelectnObject
{
    public string id { get; set; }
    public string name { get; set; }
}

Here I need to validate 2 things

1. Validate JSON structure, for example bellow one also valid (duplicated property keys)

   {
      "id": "id1",
      "id": "id2",
      "name": "name1"
   }
   

   For this I got a solution from How to validate json request body as valid json in asp.net core (but here I need a combined solution for the bellow issue also)

2. Validate all keys before get in to actions (to avoid parameter tampering) - here my input request (SelectnObject) should only contain the valid keys in the model (like id and name). If the request has any modified key, I should not allow to get in to the action. For example

   {
       "idTmp": "id1",
       "name": "name1"
   }
   

   The above request should through some exception because it is altered from 3rd party. Here I want some global configuration for both issues because I have so many actions and controllers.

Can we achieve both in a single custom filter configuration in the API?
