POST form params In API REST

I have to store the data in a BD that sends me an API, this API sends me a POST request to my server with the data as parameters Literal the documentation tells me that "the following parameters as form params"

{
  "solicitud": {
  "dato1": "1",
  "dato2": "2",
  "dato1": "3",
  .
  .
  .
  "datoN": "N",
 }
}

I want to take N data for example and store it, but I can not do it. My controller has the method as follows

[HttpPost]
public string PostConfir(Dictionary<string, string>solicitud)
{
 Ads.GuardaDat("Guarda", "dato24");//Aquí se manda a la BD para provar que si llega al post

        try//Intento trabajar el diccionario 
        {
            Dictionary<string, string> respS = solicitud["solicitud"];

            string dat = solicitud["dato1"];//Esto me genera error 
            Ads.GuardaDat(dat, "dato25");
        }

        catch (Exception ex)
        {
            Ads.GuardaDat(ex.Message, "dato25"); //Esto se guarda en BD si hay error
        }


        return "";
    }

How can I work with the data or data? Do you have to see the word form params refers to some specific parameter?

to use REST would include the Json.NET library that allows me to perform the following conversion:

REST value received (I assume this is what you receive):

 string jsonStr = "{\"solicitud\": {\"dato1\": 1,\"dato2\": 2,\"dato3\": 8}}";
 var jObjeto = JsonConvert.DeserializeObject<dynamic>(jsonStr);

now to access the values of your json:

var dato3 =  jObjeto["solicitud"]["dato3"];//8

then your driver would be as follows:

[HttpPost]
public void PostConfir(String solicitud){
 Ads.GuardaDat("Guarda", "dato24");//Aquí se manda a la BD para provar que si llega al post

        try
        {
            string jsonStr = solicitud;//"{\"solicitud\": {\"dato1\": 1,\"dato2\": 2,\"dato3\": 8}}";
             var jObjeto = JsonConvert.DeserializeObject<dynamic>(jsonStr);

            string dat = jObjeto["solicitud"]["dato25"];
            Ads.GuardaDat(dat, "dato25");
        }

        catch (Exception ex)
        {
            Ads.GuardaDat(ex.Message, "dato25");
        }
}

Now that if it's a Dictionary, what you get only converts this part then it's the same

var jObjeto = JsonConvert.DeserializeObject<dynamic>(solicitud["solicitud"]);

Do not forget to include the namespace: using Newtonsoft.Json;
