Solve HCaptcha with a proxy

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.

String

Yes

hCaptcha sitekey

proxyType

String

Yes

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

proxyAddress

String

Integer

Yes

Proxy port

proxyLogin

String

Yes

proxyPassword

String

Yes

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

isEnterprise

Boolean

Use this this parameter if you'd like your Hcaptcha to be solved with workers with highest Hcaptcha score. Note that it triples the cost of solving.

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

    print "task finished with error "+solver.error_code

Task solution object

Property	Type	Purpose
gRecaptchaResponse	String	Token string required for interacting with the submit form on the target website.
