I have spent 15 hours trying over and over to get reCAPTCHA setup. Everything works until clicking on submit and every time the result says Google thinks I’m a bot. I’ve tried everything from changing the User ID to User Password in the .env file and have tied various tagging in the server.js file. Nothing has helped thus far.

Hello,I've recently implemented reCAPTCHA v3 Enterprise on one of our website pages. I understand that reCAPTCHA v3 takes time to learn user behavior and optimize the score, but I'm seeing highly inconsistent scores even after 3 days.The main issue is that the scores returned are seemingly random. For instance, the same user performing the same action can receive scores ranging from very low (e.g., 0.1 or 0.3) to quite high (e.g., 0.9). This inconsistency could affect real users, as we rely on stable scores to filter out bots effectively.Could someone help me understand why this might be happening? Is it expected behaviour, or could there be an issue with the implementation?Also, is there a recommended way to simulate bot-like behaviour to test and better understand how reCAPTCHA scores respond to different scenarios?

I’m trying to integrate reCAPTCHA v3 with a Cloud Run backend. The client gets a token successfully, but when I verify it server-side using the reCAPTCHA API, I get a low score or timeout error.

Hi all,When I am trying to fetch a month's ReCaptcha score, I see 2 options coming up:Assessment Request ScoresExecute Request Score ScoreI am confused about which one I should use to determine the ReCaptcha score for the month. Both the scores have slightly different values.Also, it would be helpful if someone could explain the difference between "Assessment Request Scores" and "Execute Request Scores." Some short descriptions for each would be helpful.

Hi Team,                       In case If billing is generated for the customer(us), what is the billing cycle for reCAPTCHA?

Hello,I am building a backend that deals with requests from the frontend containing a Recaptcha token.I use the Python package google-cloud-recaptcha-enterprise to create the assessment and do the validation.I would like to implement automated tests for this backend. I have a testing Recaptcha site key, but I don't know how to deal with the token.Is there any way to have static test tokens that I could use in those automated tests?Otherwise, I have seen this selenium option proposed in the snippets, I am not sure, I might also simply deactivate the token check for the automated tests.

Hi, When attempting to download content from any of our blogs/resources (e.g., <URL Removed by Staff> in the Middle East, a 404 error appears. Or website support team suggests Google reCAPTCHA sometimes blocks access for users in certain regions, including parts of the Middle East, if it suspects the traffic may be suspicious. This can sometimes be triggered by factors such as device settings, browser extensions, or the use of a VPN, or the region in general. Is there any solution to resolving this? As we're worried that users in Middle Eastern locations might be affected. If that's the case, we could be missing out on important contacts for our teams, so resolving this is a priority. Regards, NES

I'm a website tester for a promotions company and I am getting regularly blocked from submitting forms for our own campaigns? I seem to be the only person who has this problem at my company and the developers can't figure out why? When I hit submit I get the 'reCAPTCHA error.' return error. Has my I.P or email / mobile details been flagged with recaptcha or something? No idea how it works. But it's very frustratingly stopping me from working. Do I contact Google? Any help would be hugely appreciated. I'm quite willing to build a shrine to you.

I've had an error pop up when setting up reCAPTCHA on a Webflow website. (It’s worth noting that Webflow doesn’t provide support for this.)Webflow includes built-in fields for the site and secret keys in its settings, which usually makes the setup simple. However, I recently received an email from Google Cloud about needing to verify something, and I’m not sure how to approach this within Webflow.Has anyone experienced this issue?

In our case we are seeing a case where recaptcha is failing our request for a user agent while it is success for the same user agent at other times. What could be the reason behind this. Sometime we got browser error, sometimes score as 0 and sometimes very low score for the same request. 

I attended a reCAPTCHA demo at Google Cloud Next, and it showcased how GCP reCAPTCHA protects websites from spam and abuse. It uses advanced risk analysis to detect bots, offering features like score-based assessments and mobile SDKs. The seamless integration with Google Cloud tools, like Cloud Armor, enhances security for high-traffic services. It’s a robust solution for enterprises.

Hello, I have a form on my website that allows non-authenticated users to complete. The form can also be completed by the user logging in. If the user has Google Services turned off, can they still access and complete the form if they are signed-in?Scenarios:1) unauthenticated user navigates to form. Prompted by reCaptcha. Google Services not deactivated. All ok. 2) unauthenticated user navigates to form. Prompted by reCaptcha. Google Services deactivated. User does not see form? What do they see?3) authenticated user navigates from within the application to the form. They will see the form? Thanks for your help. 

Hi Team, We are getting an invalid recaptcha error with a risk analysis score of 0.3. We need to know why we are getting a score of 0.3 while sending tokens to the recaptcha token validation API through the mobile app when user doing some interactions. Please find the below response and find more details. Also we got success response at intermittent time {"status_code":"invalid_recaptcha","invalid_request":"invalid reCAPTCHA token","recaptcha_response":{"riskAnalysis":{"score":0.3,"reasons":[],"extendedVerdictReasons":[],"challenge":"CHALLENGE_UNSPECIFIED"},"name":"projects/31661614596/assessments/6071678a6a000000","tokenProperties":{"valid":true,"hostname":"","createTime":"2024-11-04T12:16:55.900Z","androidPackageName":"","iosBundleId":"org.ahm-ahfc.ahfc.*****","action":"login","invalidReason":"INVALID_REASON_UNSPECIFIED"},"accountDefenderAssessment":{"labels":[]},"event":{"headers":[],"requestedUri":"","firewallPolicyEvaluation":false,"wafTokenAssessment":false,"fraudPrevention":"FRA

I have created a custom Knockout.js binding to integrate Google reCAPTCHA into my MVC application using TypeScript. However, I'm encountering an issue where the token returned by grecaptcha.execute is null when the form is submitted. Below is the code for my custom binding handler: import ko from 'knockout';ko.bindingHandlers.recaptcha = {init: function (element, valueAccessor) {var params = ko.unwrap(valueAccessor());var loadRecaptchaScript = function () {if (!document.querySelector(`script[src="https://www.google.com/recaptcha/api.js?render=${params.siteKey}"]`)) {var script = document.createElement('script');script.src=`https://www.google.com/recaptcha/api.js?render=${params.siteKey}`;script.defer = true;script.async = true;script.onload = function () {initRecaptcha();};document.head.appendChild(script);} else {initRecaptcha();}};var initRecaptcha = function () {element.addEventListener('click', function (event: any) {event.preventDefault();generateRecaptchaToken(params.siteKey

Hi, we have reCAPTCHA Enterprise 18.5.1 in our Android app. The app is live in production and reCAPTCHA works correctly. We are testing the app on a genuine, unlocked Pixel 8 running Android 15 beta 4, but we are getting a low score of 0.4 and an INVALID_REASON_UNSPECIFIED.Below an assessment response:{ tokenProperties={ valid=true, hostname=, action=ACCOUNTCREATION, createTime=Thu Oct 10 13:09:07 UTC 2024, invalidReason=INVALID_REASON_UNSPECIFIED }, riskAnalysis={ score=0.4, reasons=[] }, event={ token=03AFcWeA7ZC9iCZpVKfzMYOVLJdaPhEUHG6fJjAS1ZLs5jAZIHyt8ADPR_EAy6qA5AuZb2gxI-WIbb1bLPF46NKfraoelyFe-GeXkp2lo184rQ_Kr5ysTCOf-Uw80WXO2vtbWOB2STtNlmYREyOmbDgOjlg3qVhgKQ6XTa2n5UVcyvC08gnMrRGPf09tgyEEplpKrXzXMvGjqDeyp4YgkKHRukFKxHpH30EXRKICI3_qTZ0nClR9tBjuUXCWF6DE53aFUoIXzgcKE9PtxXHcbrHboRe0meS0bPNMvSskIJ13UN1Th7CSWkUs5LNLBj3ChkQx5xgj1y5thfju2_trlXLorBsRDR06vOAh3MG0vC9sknEM_npPQd-ujj9HaCN3CM5PO78Tf_zTFot-A4Oq1KqG6bee_SZDUFNjMbld1iwTd8eNDGqa16L-vjBWNK9830t7

I am using recaptcha Enterprise Edition, but recently found a number of invalid evaluations, including browser_error and invalid_reason_unspecified, which together account for about 20% of total requests, up until this point, invalid evaluations were only about 2%, please tell me what to do

If the Google reCAPTCHA v3 threshold is set to 0.5, users scoring below this are classified as bots. In such cases, a v2 challenge is presented. However, even after successfully solving the challenge, users are still blocked with the message "Miscellaneous activity. Please try again later." If the puzzle is completed and verified, why are users still unable to proceed?

Hey everyone!Our application which uses Recaptcha Enterprise V3 has been throwing errors in some random instances but not always and we can't seem to pinpoint any sort of situation this happens in meaning we can't reproduce the error occurring locally. The error happening is this on line 476:41 of the script. d.charCodeAt is not a function. (In 'd.charCodeAt(l)', 'd.charCodeAt' is undefined)  It seems to happening when we are adding the script on mounted of our vue instance.  const recaptchaScript = document.createElement("script"); recaptchaScript.setAttribute("src",'https://www.google.com/recaptcha/enterprise.js?onload=onloadCallback&render=explicit'); document.head.appendChild(recaptchaScript); Obviously the script is minified so we can't check to see what this "d" which chatAt is being called on.If anyone has any insights then that would be appreciated, thanks!

I think reCAPTCHA has a bug for meim Trying to log into steam and I forgot my username, so I type my email and click I’m not a robot. It gives me what feels like thousands of prompts and then it tells me I’m a robot. I’m just trying to play my video games, I’m not a robot.

Hi I'm a user of Enterprise reCaptcha and considering lowering(?) the level of ChallengeSecurityPreference from "Balance" to "Usability".I can not find any detail especially related toHow you determine which traffic is risky per each enum value; as this is not from the score-based reCaptcha and also want to understand what is the difference, too. (Such as v1 uses this many factors but v2, score-based uses this many factors....)How much increase of risk we have to expect with this change (more chance of bot attack?)And want to know if anyone from reCaptcha team can help with it.Thanks in advance.

I want to ask if it is normal that to use reCAPTCHA V3 you have to create a project in the GCP Console

I have a project developed in .Net MVC, I am trying to implement reCaptcha enterprise. It works fine on my local development environment using Google Cloud SDK Shell. But I am getting the following error when code is deployed on the dedicated windows server on GoDaddy? what am I missing? Code: RecaptchaEnterpriseServiceClient client = RecaptchaEnterpriseServiceClient.Create(); Error message: Your default credentials were not found. To set up Application Default Credentials, see https://cloud.google.com/docs/authentication/external/set-up-adc.
