javascript - Google Recaptcha - GetResponse not returning JSON - Stack Overflow

I've been implementing a new log-in page for our website, and one of the requirements is to have recaptcha on two elements in the form (one is for signing up, the other is for getting username/password reminders).

I've managed to get both recaptchas working, and they both function correctly. However when I try to use recaptcha.getResponse() or use the recaptcha.render('callback') method it does not return JSON, despite saying so in the specification. Here's the bit

The response is a JSON object

{
    "success": true|false,
    "error-codes": [...]   // optional
}

I don't get anything remotely like this in the returned data. Instead, it looks Base64 encoded, but fails any decoder that I've tried. It looks like this

Here's my code for doing the recaptchas. It may look messy, but this is just prototyping. Can anyone see if I'm doing something wrong? I think I've followed the spec exactly.

HTML (snipped for brevity)

<script type="text/javascript" src=".js?onload=onloadCallback&render=explicit" async defer></script>

<div id="div_signup_recaptcha"></div>
<div id="div_forgotdetail_recaptcha"></div>

JS/jQuery

var grecaptchaSignup, grecaptchaForgotDetail;
var verifyForgotDetailCallback = function (response) {
    console.log(response);
}

var verifySignupCallback = function (response) {
    console.log(response);
}

var onloadCallback = function () {
    grecaptchaSignup = grecaptcha.render('div_signup_recaptcha', {
        'sitekey': 'mykey',
        'callback': verifySignupCallback
    });
    grecaptchaForgotDetail = grecaptcha.render('div_forgotdetail_recaptcha', {
        'sitekey': 'mykey',
        'callback': verifyForgotDetailCallback
    });
};

Okay, I'm an idiot.

I thought I had read the specification correctly, turns out I missed the essential call to this URL

https://www.google./recaptcha/api/siteverify?secret=your_secret&response=response_string&remoteip=user_ip_address

After I plugged in my private key and the encoded response, I got my JSON object.

Hope this clears up any confusion for other people in my position :(
