Integrating google invisible reCaptcha to a Marketo form

Hi All,

Google recently launched a new captcha under the name of "invisible reCaptacha". See here for the details on the integration.

Has anyone looked into integrating it with Marketo forms?

Also google proposes a way to verify the user's response from the backend. It this a mandatory step? It apparently takes an additional field and a webhook call.

I am not sure I like it if I need to check every form submission in the back end, instead of simply blocking the submission from the front end...

Greg, you *have to* verify Captcha entries on the back end -- this is mandatory for all old Captcha technologies and all new ones. Without this step you're not stopping anyone from forging a successful result.

We use the invisible variant same as the previous "I am not a robot" style. Should be noted that some people will still get a visible challenge, as always.

I`m trying to insert the recaptach and it`s not working. I`m not sure if this is related to the fact that we don`t have the SSL set up on our Marketo Landing pages. Can you clarify me on this?

SSL isn't your problem. You'll have to include a URL so we can look at your code.

Hi @Sanford Whiteman​,

How do you integrate the invisible recaptcha with a Marketo form ?

Same as for the v2 reCAPTCHA (easier, actually, since you don't need to make space for the widget itself inside the form).  Bind grecaptcha.execute() to the form's .onSubmit().
