# NOTE: For the legacy reCAPTCHA implementation based on the HTML/HAML form, the
# 'g-recaptcha-response' field name comes from `Recaptcha::ClientHelper#recaptcha_tags` in the
# recaptcha gem, which is called from the HAML `_recaptcha_form.html.haml` form.
#
# It is used in the `Recaptcha::Verify#verify_recaptcha` to extract the value from `params`,
# if the `response` option is not passed explicitly.
#
# Instead of relying on this behavior, we are extracting and passing it explicitly. This will
# make it consistent with the newer, modern reCAPTCHA verification process as it will be
# implemented via the GraphQL API and in Vue components via the native reCAPTCHA Javascript API,
# which requires that the recaptcha response param be obtained and passed explicitly.
#
# It can also be expanded to multiple fields when we move to future alternative captcha
# implementations such as FriendlyCaptcha. See https://gitlab.com/gitlab-org/gitlab/-/issues/273480
# After this newer GraphQL/JS API process is fully supported by the backend, we can remove the
# check for the 'g-recaptcha-response' field and other HTML/HAML form-specific support.
