README

The easiest way to quickly integrate 2Captcha captcha solving service into your code to automate solving of any types of captcha.

Installation

This package can be installed via composer or manually

Composer

composer require 2captcha/2captcha

Manual

Copy src directory to your project and then require autoloader (src/autoloader.php) where needed:

require 'path/to/autoloader.php';

Configuration

TwoCaptcha instance can be created like this:

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

Also there are few options that can be configured:

$solver = new \TwoCaptcha\TwoCaptcha([
    'apiKey'           => 'YOUR_API_KEY',
    'softId'           => 123,
    'callback'         => 'https://your.site/result-receiver',
    'defaultTimeout'   => 120,
    'recaptchaTimeout' => 600,
    'pollingInterval'  => 10,
]);

TwoCaptcha instance options

Option Default value Description
softId - your software ID obtained after publishing in 2captcha sofware catalog
callback - URL of your web-sever that receives the captcha recognition result. The URl should be first registered in pingback settings of your account
defaultTimeout 120 Polling timeout in seconds for all captcha types except ReCaptcha. Defines how long the module tries to get the answer from res.php API endpoint
recaptchaTimeout 600 Polling timeout for ReCaptcha in seconds. Defines how long the module tries to get the answer from res.php API endpoint
pollingInterval 10 Interval in seconds between requests to res.php API endpoint, setting values less than 5 seconds is not recommended

IMPORTANT: once callback is defined for TwoCaptcha instance, all methods return only the captcha ID and DO NOT poll the API to get the result. The result will be sent to the callback URL. To get the answer manually use getResult method

Solve captcha

Error handling

If case of an error captch solver throws an exception. It's important to properly handle these cases. We recommend to use try catch to handle exceptions.

try {

} catch (\TwoCaptcha\Exception\ValidationException $e) {
    // invalid parameters passed
} catch (\TwoCaptcha\Exception\NetworkException $e) {
    // network error occurred
} catch (\TwoCaptcha\Exception\ApiException $e) {
    // api respond with error
} catch (\TwoCaptcha\Exception\TimeoutException $e) {
    // captcha is not solved so far
}
