For Q1 and Q2 :
send login as a POST() form.
parse the reply for ssoid.

This is not C#, it's Ada, but you probably get the idea

Code:

  procedure Login is
    Login_HTTP_Headers : Aws.Headers.List := Aws.Headers.Empty_List;
    AWS_Reply    : Aws.Response.Data;
    Header : AWS.Headers.List;
  begin
    Aws.Headers.Set.Add (Login_HTTP_Headers, "User-Agent", "AWS-BNL/1.0");

    declare
      Data : String :=  "username=" & Global_Token.Get_Username & "&" &
                         "password=" & Global_Token.Get_Password &"&" &
                         "login=true" & "&" &
                         "redirectMethod=POST" & "&" &
                         "product=home.betfair.int" & "&" &
                         "product=home.betfair.int" & "&" &
                         "url=https://www.betfair.com/";
    begin
--      Log(Me & "Login", "Data '" & Data & "'");

      AWS_Reply := Aws.Client.Post (Url          => "https://identitysso.betfair.com/api/login",
                                    Data         => Data,
                                    Content_Type => "application/x-www-form-urlencoded",
                                    Headers      => Login_HTTP_Headers,
                                    Timeouts     => Aws.Client.Timeouts (Each => 30.0));
    end ;
    Log(Me & "Login", "reply" & Aws.Response.Message_Body(AWS_Reply));
    
    -- login reply should look something like below (522 chars)
    -- <html>
    -- <head>
    --     <title>Login</title>
    -- </head>
    -- <body onload="document.postLogin.submit()">
    -- <iframe src="https://secure.img-cdn.mediaplex.com/0/16689/universal.html?page_name=loggedin&amp;loggedin=1&amp;mpuid=6081705" HEIGHT="1" WIDTH="1" FRAMEBORDER="0" ></iframe>
    -- <form name="postLogin" action="https://www.betfair.com/" method="POST">
    --     <input type="hidden" name="productToken" value="UeJkdkdojfldl�spdskFmrDhsrHQkOvHu7alH5NCldA="/>
    --     <input type="hidden" name="loginStatus" value="SUCCESS"/>
    -- </form>
    -- </body>
    -- </html>
    
    declare
      String_Reply : String := Aws.Response.Message_Body(AWS_Reply);
    begin  
      if String_Reply'length < 500 then
        raise Login_Failed with "Bad reply from server at login";
      end if;
    end ;
    
    Header := AWS.Response.Header(AWS_Reply);

    for i in 1 .. AWS.Headers.Length(Header) loop
      declare
        Head : String := AWS.Headers.Get_Line(Header,i);
        Index_First_Equal : Integer := 0;
        Index_First_Semi_Colon : Integer := 0;
--  Set-Cookie: ssoid=o604egQ2BuWCG6ij8NMlkdoemkdldmsw7eHLiWoA1vI=; Domain=.betfair.com; Path=/
      begin
        if Position(Head,"ssoid") > Integer(0) then
          Log("Login"," " & Head);
          for i in Head'range loop
            case Head(i) is
              when '=' =>
                if Index_First_Equal = 0 then
                  Index_First_Equal := i;
                end if;

              when ';' =>
                if Index_First_Semi_Colon = 0 then
                  Index_First_Semi_Colon := i;
                end if;
              when others => null;
            end case;
          end loop;
          if Index_First_Equal > Integer(0) and then Index_First_Semi_Colon > Index_First_Equal then
            Log("Login","ssoid: '" & Head(Index_First_Equal +1 .. Index_First_Semi_Colon -1) & "'");
            Global_Token.Set(Head(Index_First_Equal +1 .. Index_First_Semi_Colon -1));
          end if;
        end if;
      end;
    end loop;
  end Login;

Q3
This is a bet I placed on a horse -place market

Code:

{
	"method": "SportsAPING/v1.0/placeOrders",
	"jsonrpc": "2.0",
	"id": 16,
	"params": {
		"marketId": "1.114498460",
		"instructions": [{
			"handicap": 0,
			"limitOrder": {
				"size": 1.52510E+02,
				"price": 1.01000E+00,
				"persistenceType": "PERSIST"
			},
			"orderType": "LIMIT",
			"selectionId": 7850530,
			"side": "BACK"
		}]
	}
}

the reply is

Code:

{
	"id": 16,
	"jsonrpc": "2.0",
	"result": {
		"marketId": "1.114498460",
		"status": "SUCCESS",
		"instructionReports": [{
			"betId": "38925383410",
			"placedDate": "2014-07-04T16:36:37.000Z",
			"instruction": {
				"handicap": 0.00000E+00,
				"limitOrder": {
					"size": 1.52510E+02,
					"price": 1.01000E+00,
					"persistenceType": "PERSIST"
				},
				"orderType": "LIMIT",
				"selectionId": 7850530,
				"side": "BACK"
			},
			"status": "SUCCESS",
			"sizeMatched": 0.00000E+00,
			"averagePriceMatched": 0.00000E+00
		}]
	}
}

Note the Status on instructionReports.
Bet is placed ok.
But also note the sizeMatched = 0.
The bet is not yet matched.
Placed/accepted, but not matched.

Q1/Q2 - see https://github.com/betfair/API-NG-sample-code

This contains C# code covering interactive login

Q3 - no, there is no automatic callback functionality.

There is talk about Betfair providing a push-based API, but I've not seen any concrete news on that yet.
