API

Props

• sitekey (required) Your sitekey

• theme (optional) The color theme of the widget
• hl (optional) Forces the widget to render in a specific language. Auto-detects the user's language if unspecified.

Events

• verify(response) The name of your callback function, executed when the user submits a successful response. The g-recaptcha-response token is passed to your callback
• expire The name of your callback function, executed when the reCAPTCHA response expires and the user needs to re-verify
• fail The name of your callback function, executed when reCAPTCHA encounters an error (usually network connectivity) and cannot continue until connectivity is restored. If you specify a function here, you are responsible for informing the user that they should retry
