If the provided code is not sufficient for your use case, you can extend the provided services like so:
Passioneight\PimcoreGoogleRecaptcha\Service\Decoder\TokenDecoderInterface:
class: AppBundle\Service\GoogleRecaptcha\Decoder\TokenDecoder
Passioneight\PimcoreGoogleRecaptcha\Service\Parser\ResponseParserInterface:
class: AppBundle\Service\GoogleRecaptcha\Parser\ResponseParser
Passioneight\PimcoreGoogleRecaptcha\Service\Validator\ResponseValidatorInterface:
class: AppBundle\Service\GoogleRecaptcha\Validator\ResponseValidator
Consider extending the following classes instead of starting from scratch:
Passioneight\PimcoreGoogleRecaptcha\Service\Decoder\AbstractTokenDecoder
Passioneight\PimcoreGoogleRecaptcha\Service\Parser\AbstractResponseParser
Passioneight\PimcoreGoogleRecaptcha\Service\Validator\AbstractResponseValidator
