With SDK (recommended):

PHP

// https://github.com/2captcha/2captcha-php

require(__DIR__ . '/../src/autoloader.php');

$solver = new \TwoCaptcha\TwoCaptcha('YOUR_API_KEY');

try {
    $result = $solver->keycaptcha([
        's_s_c_user_id'          => 184015,
        's_s_c_session_id'       => '9ff29e0176e78eb7ba59314f92dbac1b',
        's_s_c_web_server_sign'  => '964635241a3e5e76980f2572e5f63452',
        's_s_c_web_server_sign2' => '3ca802a38ffc5831fa293ac2819b1204',
        'url'                    => 'https://2captcha.com/demo/keycaptcha',
    ]);
} catch (\Exception $e) {
    die($e->getMessage());
}

die('Captcha solved: ' . $result->code);

Python

import sys
import os

sys.path.append(os.path.dirname(os.path.dirname(os.path.realpath(__file__))))

from twocaptcha import TwoCaptcha

Manually:

Send a HTTP GET or POST request to our API URL: https://2captcha.com/in.php with method set to keycaptcha and provide values found on previous step in your request as values for corresponding request parameters and also full page URL as value for pageurl.
Request URL example:
https://2captcha.com/in.php?key=1abc234de56fab7c89012d34e56fa7b8&s_s_c_user_id=10&s_s_c_session_id=9ff29e0176e78eb7ba59314f92dbac1b&s_s_c_web_server_sign=964635241a3e5e76980f2572e5f63452&s_s_c_web_server_sign2=3ca802a38ffc5831fa293ac2819b1204&method=keycaptcha&pageurl=http://2captcha.com/demo/keycaptcha
If everything is fine server will return the ID of your captcha:

OK|2122988149
Otherwise server will return an error code.
After 15-20 seconds send GET request to get the result:

GET https://2captcha.com/res.php?key=YOUR_API_KEY&action=get&id=2122988149
If captcha is already solved server will respond with the answer token:

OK|ebdb5a6bf76da6887db60ef2041ab946|964635241a3e5e76980f2572e5f63452|http://back10.keycaptcha.com/swfs/ckc/5bded85426de3c57a7529a84bd0d4d08-|9ff29e0176e78eb7ba59314f92dbac1b|1
If captcha is not solved yet server will return CAPCHA_NOT_READY result. Repeat your request in 5 seconds. If something went wrong server will return an error code.

Locate and delete the following block which inclides keycaptcha JavaScript file:

<script language="JavaScript" src="http://backs.keycaptcha.com/swfs/cap.js"></script>

Locate and delete the div with id="div_for_keycaptcha":
```
<div id="div_for_keycaptcha"...>...</div>
```
Locate the element with id="capcode" and change it's value to the response received from our server:
```
<input name="capcode" id="capcode" value="1|2|3|4|5" type="hidden">
```
Click on "Check" button to submit the form.
