Test invisible recaptcha

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?

I am still struggling a little bit with this but I found that the following things make invisible recaptcha puzzle more likely to appear:

Log into the recaptcha admin and set it to maximum security
Open your site from an incognito tab.
Sometimes leaving the login page open and trying to login after some time has passed seems to trigger the recaptcha puzzle.

I must admit though that these don't work all of the times and there are times that I really struggle to get it to work.

Update: It seems a bit strange but I have found that the invisible ReCaptcha is more likely to appear when I submit a form using the Enter key instead of pressing a button with the mouse.

2022 Answer that worked for me!

Please do give this one a go as it's the only one that actually worked for me after hours of testing.

Go to your reCAPTCHA admin account: https://www.google.com/recaptcha/admin/
Go to your site settings
Move the "Security Preference" slider all the way to the right to make reCAPTCHA trigger more often
Open an Incognito window, or even better a secure web browser with a built in encrypted proxy (I think this makes reCAPTCHA more suspicious of your browser) - I used a browser call Epic Browser, which is also Chromium based: https://www.epicbrowser.com/. Note: Just using Incognito on Chrome did not work for me, hence why I went to go use Epic.
Attempt to submit your form - you should hopefully receive the popup check!

As others mentioned you can also test if the browser alone triggers reCAPTCHA check by going to https://www.google.com/recaptcha/api2/demo?invisible=true and submitting the form.

This finally helped me as I was going crazy thinking my reCAPTCHA setup was not working and that I coded something wrong... But no, it was working! Just not very suspicious apparently.

I hope this helps someone as it did me!

Go thru the steps to test the re-captcha with dev tools open. Go to the network tab and find the POST where the form is submitted. Right click that line and copy as cURL.

Paste into the CLI and voila, you get the failure and the output of the cURL is the HTML that the server sent back.

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

Go to this url https://www.google.com/recaptcha/api2/demo?invisible=true (notice the url has ?invisible=true parameter at the end)
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.
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

Go to this url, https://www.google.com/recaptcha/api2/demo (notice, i have removed the ?invisible=true parameter from the url)
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.

You can test invisible recaptcha by using Chrome emulator.

You will need to add a new custom device (BOT) in developer tools, and set User Agent String to Googlebot/2.1 on Desktop. Then use the new BOT device when testing on your site to trigger the recaptcha authentication.

Note: ReCaptcha v3 will still let the google bot pass as it has a score of 0.9 when emulating in Chrome.

V2 INVISIBLE In this case just use Incognito or Private browsing to see it works.

Here is the testing link where ReCaptcha is working: https://www.google.com/recaptcha/api2/demo?invisible=true

Please give the credits to the guys in comments below.

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.)

The way I tackled it:

Go to your POST to google.com/recaptcha/api/siteverify
Before the response is returned, set the success property in the response to false.

I'm using Guzzle in Laravel (thanks to this example):

$response = $client->post('https://www.google.com/recaptcha/api/siteverify', [
    'query' => [
        'secret' => env('RECAPTCHA_V3_SECRET_KEY'),
        'response' => $value,
        'remoteip' => $_SERVER['REMOTE_ADDR'],
    ]
]);

$body = $response->getBody();

$contents = json_decode($body->getContents());

$contents->success = false;

return $contents;

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&#038;render=explicit&#038;hl=de-CH'

Invisible recaptcha check fails if you try to access your page via automated tests (in my case chrome browser) since chrome has a feature to recognize if the browsers is controlled by such software... so try to create easy tests in Python or Java(+webdriver), to see if recaptcha is implemented correctly.

I found an excellent answer that works as of 2018-08-27.

In Chrome, hit F12 to open the Developer Console. Next, toggle the Device Toolbar, select a device and click Edit... Now, add a new device with the following configuration:
