## Installation
2captcha-java artifact is available in [Maven Central]

## Configuration
`TwoCaptcha` instance can be created like this:
```java
TwoCaptcha solver = new TwoCaptcha('YOUR_API_KEY');
```
Also there are few options that can be configured:
```java
solver.setHost("2captcha.com");
solver.setSoftId(123);
solver.setCallback("https://your.site/result-receiver");
solver.setDefaultTimeout(120);
solver.setRecaptchaTimeout(600);
solver.setPollingInterval(10);
solver.setExtendedResponse(1);
```

### TwoCaptcha instance options

| Option           | Default value| Description                                                                                                                                        |
|------------------| ------------ |----------------------------------------------------------------------------------------------------------------------------------------------------|
| host             |`2captcha.com`| API server. You can set it to `rucaptcha.com` if your account is registered there                                                                  |
| softId           | 4581         | your software ID obtained after publishing in [2captcha software 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                              |
| extendedResponse | 0            | Json or String format response from `res.php` API endpoint, extendedResponse = 1 returns JSON format response. Suitable for [ClickCaptcha](#clickcaptcha), [Canvas](#canvas) |

>  [!IMPORTANT]
>  Once *callback URL* is defined for `TwoCaptcha` instance with `setCallback`, 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](#send--getresult)

> [!TIP]
> Use the `extendedResponse(1)` setting to obtain an extended response for the captcha. When using `extendedResponse(1)`, the response will be presented as a `JSON` string. Utilizing the extended response `extendedResponse(1)` will be helpful when solving captchas such as [ClickCaptcha](#clickcaptcha).

## Solve captcha
When you submit any image-based captcha use can provide additional options to help 2captcha workers to solve it properly.

| hintText      | -             | hint or task text shown to workers with the captcha                                                |

## Proxies
You can pass your proxy as an additional argument for methods: recaptcha, funcaptcha, geetest, geetest v4, keycaptcha, capy puzzle, lemin, turnstile, amazon waf and etc. The proxy will be forwarded to the API to solve the captcha.

We have our own proxies that we can offer you. [Buy residential proxies](https://2captcha.com/proxy/residential-proxies) for avoid restrictions and blocks. [Quick start](https://2captcha.com/proxy?openAddTrafficModal=true).

```java
captcha.setProxy("HTTPS", "login:password@IP_address:PORT");
```

## Error handling
If case of an error captcha solver throws an exception. It's important to properly handle these cases. We recommend to use `try catch` to handle exceptions. The list of all errors can be found in the [API documentation](https://2captcha.com/2captcha-api#list-of-inphp-errors).

```java
try {
    solver.solve(captcha);
} catch (ValidationException e) {
    // invalid parameters passed
} catch (NetworkException e) {
    // network error occurred
} catch (ApiException e) {
    // api respond with error
} catch (TimeoutException e) {
    // captcha is not solved so far
}
```

## Examples
Examples of solving all supported captcha types are located in the [examples] directory.
