Example usage Kinvey via Https:

function TKinveyRest.GetCollection: string;
var
  IdHTTP: TIdHTTP;
  IdIOHandler: TIdSSLIOHandlerSocketOpenSSL;
  response : string;
  encodedHeader : string;
begin
  try
    IdIOHandler := TIdSSLIOHandlerSocketOpenSSL.Create(nil);
    IdIOHandler.ReadTimeout := IdTimeoutInfinite;
    IdIOHandler.ConnectTimeout := IdTimeoutInfinite;
    IdHTTP := TIdHTTP.Create(nil);
    try
      IdHTTP.IOHandler := IdIOHandler;
      IdHTTP.Request.Connection := 'Keep-Alive';
      IdIOHandler.SSLOptions.Method := sslvSSLv23;
      IdHTTP.Request.CustomHeaders.Clear;
      encodedHeader := TIdEncoderMIME.EncodeString(FOptions.AppId + ':' + FOptions.MasterSecret);
      IdHTTP.Request.CustomHeaders.Values['Authorization'] := 'Basic ' + encodedHeader;
      IdHTTP.Request.CustomHeaders.Values['X-Kinvey-API-Version'] := '3';
      IdHTTP.Request.ContentType := 'application/json';
      response := IdHTTP.Get('https://baas.kinvey.com/appdata/'+FOptions.AppId+'/'+FOptions.Collection+'/');
      result := response;
    finally
      IdHTTP.Free;
    end;
  finally
    IdIOHandler.Free;
  end;
end;

Example usage Firebase via Https:

function TFirebaseRest.GetCollection: string;
var
  IdHTTP: TIdHTTP;
  IdIOHandler: TIdSSLIOHandlerSocketOpenSSL;
  response : string;
begin
  try
    IdIOHandler := TIdSSLIOHandlerSocketOpenSSL.Create(nil);
    IdIOHandler.ReadTimeout := IdTimeoutInfinite;
    IdIOHandler.ConnectTimeout := IdTimeoutInfinite;
    IdHTTP := TIdHTTP.Create(nil);
    try
      IdHTTP.IOHandler := IdIOHandler;
      IdHTTP.ReadTimeout := IdTimeoutInfinite;
      IdHTTP.Request.Connection := 'Keep-Alive';
      IdIOHandler.SSLOptions.Method := sslvSSLv23;
      IdHTTP.Request.CustomHeaders.Clear;
      IdHTTP.Request.ContentType := 'application/json';
      response := IdHTTP.Get('https://delphitestproject.firebaseio.com/.json?auth='+FOptions.FirebaseAuth);
      result := response;
    finally
      IdHTTP.Free;
    end;
  finally
    IdIOHandler.Free;
  end;
end;

Example usage Parse.com via Https:

procedure TParseRest.GetCollection: string;
var
  response : string;
  JSONToSend: TStringStream;
begin
  JSONToSend := TStringStream.Create('{}');
  IdHTTP1.Request.Connection := 'Keep-Alive';
