ReCaptchaV2Token

reCAPTCHA V2 is one of the most common CAPTCHA systems. It typically presents as a checkbox labeled "I'm not a robot" and may require users to complete image selection challenges (e.g., "select all squares with traffic lights").

Successful completion returns a gRecaptchaResponse token which you submit with your target form.

This variant uses your proxy. If you do not need proxy control or want the provider to use their own IPs, use ReCaptchaV2TokenProxyLess.

How to find the Website Key (sitekey)

The sitekey is a unique identifier for the reCAPTCHA instance on the target website. You can find it using several methods.

Method 1: Elements Tab

Open DevTools in your browser and go to the Elements tab.
Search (Ctrl + F) for data-sitekey or g-recaptcha.
The key is usually found in a div element: <div class="g-recaptcha" data-sitekey="THIS_IS_THE_SITEKEY"></div>

Finding sitekey in Elements

Method 2: Network Tab

Open DevTools and go to the Network tab.
Reload the page and filter for recaptcha.
Look for requests to google.com/recaptcha/api2/anchor.
The sitekey is passed in the k parameter: ...&k=SITE_KEY_HERE.

Quick Console Script

Run this script in the browser console to automatically extract the sitekey:

(() => {
    let key = null;
    document.querySelectorAll('.g-recaptcha, [data-sitekey]').forEach((el) => {
        if (el.dataset.sitekey) key = el.dataset.sitekey;
    });
    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

Once you receive the solution token, you must submit it to the target website.

Hidden Textarea: Most sites have a hidden <textarea id="g-recaptcha-response">. You can set its value using JavaScript:
```
document.getElementById('g-recaptcha-response').innerHTML = 'TOKEN_HERE';
```
Callback Function: Some sites use a callback. You can find and trigger it via:
```
window.___grecaptcha_cfg.clients[0].aa.l.callback('TOKEN_HERE');
```
Note: The exact path to the callback may vary depending on the reCAPTCHA version and implementation.

In automation tools like Puppeteer or Selenium, you execute these snippets via page.evaluate().

Optional Parameters

Set isInvisible to true when the reCAPTCHA appears without a visible checkbox. The challenge triggers automatically on a user action like a button click.

The recaptchaDataSValue and isSession parameters are not supported by all providers. Test with your target site to verify compatibility.

Optional fields are not guaranteed across providers

Required fields are guaranteed across every provider that supports this task. Optional fields may be honored by some providers and silently ignored by others. AnySolver does not document per-provider parameter support, so before relying on an optional field, check that provider's own docs for the task you are using.

Request Schema

Field	Type	Required	Description
`clientKey`*	string	Yes	Your API key from the AnySolver dashboard. Example: `your-api-key-from-dashboard`
`task`*	object	Yes	View task properties
`provider`		No	Specific provider to use. If omitted, automatic routing selects the best provider. Example: `CapSolver`
`selectionMode`		No	Read more at the routing strategies docs. Example: `autoCheapest`
`keyPoolMode`		No	Example: `all`

Task Object Properties

The task field accepts an object with the following properties:

Field	Type	Required	Description
`type`*		Yes
`websiteURL`*	URL	Yes	Full URL of the page where the CAPTCHA is displayed. Example: `https://www.google.com/recaptcha/api2/demo`

`pageTitle`*	string	Yes	Title of the target page (document.title). Some providers use it as an additional hint when solving token-based reCAPTCHA tasks. Example: `reCAPTCHA demo`
`proxy`*	string \| object	Yes	View proxy configuration
`isInvisible`	boolean	No	Set to true when the widget is invisible, for example when the iframe URL contains size=invisible or the challenge starts after a button click without showing a checkbox first. Example: `false`
`userAgent`	string	No	Browser User-Agent string. Must match the browser used on the target page. Not all providers properly support this parameter. Verify the compatibility with the provider you are using. Example: `Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/122.0.0.0 Safari/537.36`

`pageAction`	string	No	Action passed to grecaptcha.execute() or grecaptcha.enterprise.execute(), such as verify or submit. This is mainly relevant on enterprise flows and should match the page JavaScript exactly. Example: `verify`
`apiDomain`	string	No	Domain used to load reCAPTCHA. Use google.com for standard widgets or recaptcha.net when the page loads the API from recaptcha.net or www.recaptcha.net. Example: `www.recaptcha.net`
`isSession`	boolean	No	Enable session mode to receive worker session cookies together with the token. Only supported by providers that expose session-cookie responses. Example: `false`
`recaptchaDataSValue`	string	No	Value of the data-s parameter used on some Google-owned pages and other protected flows. It is short-lived and should be extracted fresh for every solve attempt. Example: `data-s_example_value`

Response Schema

Field	Type	Required	Description
