Recaptcha V2 with Formtoemailpro - recaptcha

Question

Has anyone edited formtoemailpro to use Recaptcha v2? This is the formtoemailpro developer version which gives you a PHP script: (https://formtoemail.com/developer_pricing.php)
I tried changing
// Check reCAPTCHA
if($reCAPTCHA)
{
require_once('recaptchalib.php');
$resp = recaptcha_check_answer($privatekey,$_SERVER["REMOTE_ADDR"],$_REQUEST["recaptcha_challenge_field"],$_REQUEST["recaptcha_response_field"]);
if(!$resp->is_valid)
{
$errors[] = "The reCAPTCHA wasn't entered correctly. Go back and try it again (reCAPTCHA said: " . $resp->error . ")";
}
unset($_REQUEST["recaptcha_challenge_field"]);
unset($_REQUEST["recaptcha_response_field"]);
}
to
// Check reCAPTCHA
if($reCAPTCHA)
{
//require_once('recaptchalib.php');
//$resp = recaptcha_check_answer($privatekey,$_SERVER["REMOTE_ADDR"],$_REQUEST["recaptcha_challenge_field"],$_REQUEST["recaptcha_response_field"]);
$resp = recaptcha_check_answer($privatekey,$_SERVER["REMOTE_ADDR"],$_REQUEST["g-recaptcha-response"]);
if(!$resp->is_valid)
{
$errors[] = "The reCAPTCHA wasn't entered correctly. Go back and try it again (reCAPTCHA said: " . $resp->error . ")";
}
unset($_REQUEST["g-recaptcha-response"]);
}
But got errors.

Can anyone point me to the right direction?

I think I have a solution, please feel free to test and critique:
In place of the existing reCaptcha lines in formtoemailpro as above, enter the following:
// Check reCAPTCHA
if($reCAPTCHA)
{
if(isset($_REQUEST['g-recaptcha-response'])){
$captcha=$_POST['g-recaptcha-response'];
}
if(!$captcha){
echo '<h2>Please check the the captcha form.</h2>';
exit;
}
$response=file_get_contents("https://www.google.com/recaptcha/api/siteverify?secret=$privatekey&response=".$captcha."&remoteip=".$_SERVER['REMOTE_ADDR']);
if($response.success==true)
{
unset($_REQUEST['g-recaptcha-response']);
}
}
Thank you
