Есть код на php (https://gist.github.com/moorer2k/562...09ffb402ca6b65)
Мне его нужно повторить на Delphi

Что сделал:

Код:

function GetAuthToken(var Parse:string):string;
begin
  delete(Parse,1,pos('code=',Parse)+4);
  Result:=copy(Parse,1,pos('"',Parse)-1);
end;

function GetCookie(var Parse:string):string;
begin
  delete(Parse,1,pos('set-cookie',Parse)+11);
  Result:=copy(Parse,1,pos(';',Parse)-1);
end;

//function postData($uri, $postData, $returnCookie = false, $cookieSession = '', $lastRequest = false) {
function postData(uri,postData:string; returnCookie:Boolean=False; cookieSession:string=''; lastRequest:Boolean=False):string;
var
  Request:TStringList;
  Response:TStringStream;
  C:string;
begin
  Result:='';
  Request:=TStringList.Create;
  Response:=TStringStream.Create('');
  if Length(cookieSession)>1 then
  begin
    Request.Add(postData);
    Form1.idhtp1.Request.CustomHeaders.Text:='Cookie: '+cookieSession;
    Form1.idhtp1.Request.Referer:='https://auth.riotgames.com/authorize?redirect_uri=http://localhost/oauth2-callback&client_id=leagueconnect&response_type=code&scope=openid&ui_locales=en-US';
    Form1.idhtp1.Request.ContentType:='application/json';
    Form1.idhtp1.Post(uri,Request,Response);
  end else if lastRequest then
  begin
    Request.Add(postData);
    Form1.idhtp1.Request.CustomHeaders.Text:='';
    Form1.idhtp1.Request.Referer:='';
    Form1.idhtp1.Request.ContentType:='application/x-www-form-urlencoded; charset=utf-8';
    Form1.idhtp1.Request.Accept:='*';
    Form1.idhtp1.Request.UserAgent:='LoL%20Friends/490 CFNetwork/758.0.2 Darwin/15.0.0';
    Form1.idhtp1.Post(uri,Request,Response);
  end else
  begin
    Request.Add(postData);
    Form1.idhtp1.Request.CustomHeaders.Text:='';
    Form1.idhtp1.Request.Referer:='https://auth.riotgames.com/authorize?redirect_uri=http://localhost/oauth2-callback&client_id=leagueconnect&response_type=code&scope=openid&ui_locales=en-US';
    Form1.idhtp1.Request.ContentType:='application/json';
    Form1.idhtp1.Request.Accept:='';
    Form1.idhtp1.Request.UserAgent:='';
    Form1.idhtp1.Post(uri,Request,Response);
  end;
  Result:=Response.DataString;
  if returnCookie then
  begin
    C:=Form1.idhtp1.Response.RawHeaders.Text;
    Result:=GetCookie(C);
  end;  
  Request.Free;
  Response.Free;
end;
//protected function Login($username, $password, $region, $lang) 	{
procedure Login(username,password,region,lang:string);
const URLs='https://auth.riotgames.com/authz/status';
      URLa='https://auth.riotgames.com/authz/auth';
      URLt='https://auth.riotgames.com/token';
var
  session1,session2,authToken,Request,jRequest:string;
begin
  Request:='{"query":"redirect_uri=http:\/\/localhost\/oauth2-callback&client_id=leagueconnect&response_type=code&scope=openid&ui_locales=en-US"}';
  session1:=postData(URLs,Request,True);
  Request:='{"username":"'+username+'","password":"'+password+'","region":"'+region+'","remember":"true","lang":"'+lang+'"}';
  session2:=postData(URLa,Request,False,session1);
  authToken:=GetAuthToken(session2);
  Request:='grant_type=authorization_code&code='+Trim(authToken)+'&redirect_uri=http%3A%2F%2Flocalhost%2Foauth2-callback&client_id=leagueconnect&client_secret=amVYw7iK_qSaGUNqxRvzgs16EMgdEUdu1mDVdMNJDC4';
  jRequest:=postData(URLt,Request,False,'',True);//Тут ошибка 400 Bad Request
end;

Парни утверждают что на пыхе этот алгоритм работает.
Подскажите пожалуйста что у меня не так?

P.S.
