ReCaptchaV3Token

reCAPTCHA V3 runs entirely in the background. No checkbox, no image challenges. Instead of a challenge, it assigns a score from 0.0 (bot) to 1.0 (human). The website decides what to do based on the score (block, allow, or require additional verification).

Common score thresholds:

• 0.1–0.3: likely bot
• 0.5: uncertain
• 0.7–0.9: likely human

Successful completion returns a gRecaptchaResponse token like V2, but the site verifies it with a score check.

This variant uses your proxy. Use ReCaptchaV3TokenProxyLess if you don't need proxy control.

How the Score System Works

The minScore parameter sets the minimum score you need. A higher value means the provider must work harder to appear human.

Common values:

• 0.3: easy
• 0.5: moderate
• 0.7: standard (most common)
• 0.9: hard (not all providers achieve this reliably)

Finding the Action Parameter

The pageAction is critical for V3. It tells Google what the user is doing. If the action does not match what the site expects, the token might be rejected.

How to find it:

1. Open DevTools and go to the Sources or Network tab.
2. Search (Ctrl + Shift + F) for grecaptcha.execute in the page JavaScript.
3. Look for: grecaptcha.execute('sitekey', {action: 'THIS_VALUE'}).

Common values include login, submit, register, homepage, or verify.

Console script to find action:

Run this script in the browser console to extract the action from inline scripts:

(() => {
    const scripts = document.querySelectorAll('script:not([src])');
    const pattern = /grecaptcha\.execute\s*\(\s*['"][^'"]+['"]\s*,\s*\{\s*action\s*:\s*['"]([^'"]+)['"]/g;
    const actions = [];
    scripts.forEach((s) => {
        let m;
        while ((m = pattern.exec(s.textContent)) !== null) actions.push(m[1]);
    });
    if (actions.length) console.log('Actions found:', actions);
    else console.log('No actions found in inline scripts. Check external JS files.');
})();

Finding the Website Key

You can use the same methods as V2 to find the sitekey.

• Elements Tab: Search for data-sitekey.
• Network Tab: Filter for recaptcha and look for the k= parameter in requests to anchor.

For V3, you should also check for:

• grecaptcha.execute('THIS_KEY', ...) in JavaScript.
• The render parameter in the script URL: recaptcha/api.js?render=THIS_KEY.

Quick Console Script:

(() => {
    let key = null;
    // Check data-sitekey attributes
    document.querySelectorAll('[data-sitekey]').forEach((el) => {
        if (el.dataset.sitekey) key = el.dataset.sitekey;
    });
    // Check script render parameter
    if (!key) {
        document.querySelectorAll('script[src*="recaptcha"]').forEach((s) => {
            const url = new URL(s.src, location.href);
            const render = url.searchParams.get('render');
            if (render && render !== 'explicit') key = render;
        });
    }
    // Check iframe
    if (!key) {
        const iframe = document.querySelector('iframe[src*="recaptcha"]');
        if (iframe) key = new URL(iframe.src).searchParams.get('k');
    }
    console.log('sitekey:', key || 'Not found');
})();

Submitting the Token

Submit the token to your form or callback, just like in V2. Note that V3 tokens typically have shorter validity windows than V2 tokens.
