Solve HCaptcha automatically via a proxy - HCaptchaTask

Hcaptcha devs call their captcha "a drop-in replacement for Recaptcha". We tried to create the same thing in our API, so task properties are absolutely the same as in RecaptchaV2Task except for the "type" property.

Important notice about User-Agent value. Previously it was possible to specify your own User-Agent for the tasks, but this had changed. Instead we provide the worker's user-agent which you need to use to bypass paid version of Hcaptcha. This was changed because nowadays it is almost impossible to emulate an alien user-agent in another platform, for example Chrome user-agent in Firefox. Browsers have large number of secondary artefacts besides navigator.userAgent, which belong specifically to one or another platform.

Captcha example

Task object

Property

Type

Required

Purpose

type

String

Yes

HCaptchaTask

websiteURL

String

Yes

Address of a target web page. Can be located anywhere on the web site, even in a member area. Our workers don't navigate there but simulate the visit instead.

websiteKey

String

Yes

hCaptcha sitekey

proxyType

String

Yes

Type of proxy
http - usual http/https proxy
socks4 - socks4 proxy
socks5 - socks5 proxy

proxyAddress

String

Yes

Proxy IP address ipv4/ipv6. No host names or IP addresses from local networks.

proxyPort

Integer

Yes

Proxy port

proxyLogin

String

proxyPassword

String

Proxy password

~~userAgent~~

~~String~~

~~Yes~~

~~Provide the User Agent you are using to navigate the website. Our workers will use same value during Hcaptcha solving process.~~
Deprecated. Instead, use User-Agent from our workers which is returned by "getTaskResult" method.

isInvisible

Boolean

Specify whether or not Hcaptcha is invisible. This will render an appropriate widget for our workers.

enterprisePayload

Object

Additional parameters which we'll use to rfeature3,ender Hcaptcha widget for Enterprise version.

Property	Type	Required
rqdata	String	No
sentry	Boolean	No
apiEndpoint	String	No
endpoint	String	No
reportapi	String	No
assethost	String	No
imghost	String	No

Response example

JSON with no errors

          {
    "errorId": 0,
    "taskId": 7654321
}

JSON with an error

          {
    "errorId": 1,
    "errorCode": "ERROR_KEY_DOES_NOT_EXIST",
    "errorDescription": "Account authorization key not found in the system"
}

Retrieve the solution

Use method getTaskResult to request the solution. Give the worker about 5 seconds before making your first request. If the worker is still busy, retry in 3 seconds.

Task solution object

Property	Type	Purpose
gRecaptchaResponse	String	Token string required for interacting with the submit form on the target website.
respKey	String	Output of "window.hcaptcha.getRespKey()" function when it is available. Some websites use it for additional verification.
userAgent	String	User-Agent of worker's browser. Use it when you submit the response token.
