DESCRIPTION

This subclass of Mojolicious::Plugin::ReCAPTCHAv2 adds a helper that returns a Mojo::Promise, allowing you to use it in a non-blocking/async manner.

HELPERS

Mojolicious::Plugin::ReCAPTCHAv2Async inherits all helpers from Mojolicious::Plugin::ReCAPTCHAv2 and adds the following ones:

recaptcha_verify_p

This helper returns a Mojo::Promise that will resolve if the reCAPTCHA service believes that the challenge was solved by a human, and it will reject if there was a failure. The failure can be caused either by an error or because the service believes the challenge was attempted by a bot.

In case of errors, those will be passed through the rejection. See the recaptcha_get_errors helper for more information about the possible errors.
