Test invisible recaptcha

Question

We have integrated invisible recaptcha in one of our websites. Whenever we submit the form it automatically submits.

I read in some google groups that we would get a challenge when accessed on edge browser. But for us, it is automatically submitted.

Any specific steps to test the invisible recaptcha?

Everyone was talking about using the demo page to test it out. What we get after we tested and how it should looks like is what everyone miss out. Or probably thats why most of us are still searching for the answer.

Even though this question is 3yrs old, still its not clear how this recaptcha works. Iam trying my best to break in steps. Let me know if its works for you.

Google Demo page test

Important

Follow the steps below in the Incognito window

with the parameter

1. Go to this url https://www.google.com/recaptcha/api2/demo?invisible=true (notice the url has ?invisible=true parameter at the end)
2. You should see nothing but an pre-filled form with an active 'submit' button with no 'checkbox' captcha, instead you will see the badge at the bottom right.
3. Click the 'Submit' button and you should see something like this. This is the verification check point.

4. Select the relevant image and the page should redirect with the message saying
Verification Success... Hooray!

But what if you didn't see any image?

If you are not seeing any verification image and the form submits with

Verification Success... Hooray!

then either the form is not working (mostly that's not the case) or you need to clear your browser cache and try again.

without the parameter

1. Go to this url, https://www.google.com/recaptcha/api2/demo (notice, i have removed the ?invisible=true parameter from the url)
2. You should see the good 'ol robot checkbox captcha above the 'Submit' button.

3. Also you can notice there won't be captcha badge at the bottom right.

Your Website

Try it in the Incognito window

• Just like the demo you should get the same result in your website if you use invisible captcha. (Don't worry about the url parameters)
• If your page displayed the captcha badge at the bottom right then after clicking the 'submit' button you should see the popup image window.
• If you do not get any popup and the form submits then there's an issue with your captcha or could be browser cache.

Not seeing the checkbox ... ?

Here are some notes from reCaptcha help page - https://support.google.com/recaptcha#6223828

If you're seeing this reCAPTCHA challenge, your browser environment doesn't support the reCAPTCHA checkbox widget.
There are a few steps you can take to improve your experience:

• Make sure your browser is fully updated (see minimum browser requirements)
• Check that JavaScript is enabled in your browser
• Try disabling plugins that might conflict with reCAPTCHA

Please note that some sites may have incorrectly integrated with reCAPTCHA - in this case please contact the site's webmaster.

WordPress Contact Form 7 users

You do not need to add the [recaptcha] tag.

reCAPTCHA v3 doesn’t need a CAPTCHA widget (the “I’m not a robot” checkbox used in reCAPTCHA v2) to work, so [recaptcha] form-tags are no longer necessary. If [recaptcha] form-tags are found in a form template, Contact Form 7 5.1 or higher ignores them and replaces them with an empty string.

As of 2019-06-21, it appears that it is sufficient with Google Chrome (v74.0.3729.169) to bring up a new incognito window to force the recaptcha to execute. (I had needed this for our own recaptcha testing, so I'm glad I found it.)

If you did not implement the code yourself, the first thing to check is the source code, see if reCaptcha is actually loaded. When using a CMS, I search for this line (or similar):

script type='text/javascript' async defer src='https://www.google.com/recaptcha/api.js?onload=renderInvisibleReCaptcha&render=explicit&hl=de-CH'
