<h4>Compatibility</h4>
On a WP Multisite you can either activate the plugin network wide or on a single site.
Activated on a single site everything works as usual.
With network activation entering the API key and setting up where a captcha is required 
is up to the network admin. A blog admin can override the API key e.g. when his blog is 
running under his/her own domain name.
<h4>Known Limitations</h4>
<ul>
<li>
You can’t have more than one old style reCaptcha on a page. This is a limitiation of 
reCaptcha itself. If that’s an issue for you, you should use the no Captcha Form.
</li>
<li>
A No Captcha definitely requires client side JavaScript enabled. That’s how it does its 
sophisticated bot detection magic. There is no fallback. If your visitor does not have 
JS enabled the captcha test will not let him through.
</li>
<li>
On a Contact Form 7 when the reCaptcha is disabled (e.g. for logged in users) the field 
label will be still visible. This is due to CF7 Shortcode architecture, and can’t be fixed.
To handle this there is a filter <code>recaptcha_disabled_html</code>. You can return a message for your logged-in 
users here. Check out the <a href="https://github.com/tareq1988/wp-recaptcha-integration" rel="nofollow ugc">GitHub Repo</a> for details.
</li>
<li>
As of version 4.3 CF7 comes with its own recaptcha. Both are supposed to work together. 
I you want to keep the WP ReCaptcha functionality, e.g. if you want to hide the captcha 
from known users, leave the integration in the CF7 settings unconfigured.
</li>
<li>
Old style reCaptcha does not work together with WooCommerce.
</li>
<li>
In WooCommerce the reset password form can not be protected by a captcha. Woocommerce does 
not fire any action in the lost password form, so there is no way for the plugin to hook in. 
Take a look at <a href="https://wordpress.org/support/topic/captcha-not-showing-on-lost-password-page?replies=7" rel="ugc">this thread</a> for a workaround.
</li>
<li>
Due to a lack of filters there is no (and as far as one can see, there will never be) 
support for the MailPoet subscription form.
</li>
</ul>
<h3>Plugin API</h3>
The plugin offers some filters to allow themes and other plugins to hook in.
See <a href="https://github.com/tareq1988/wp-recaptcha-integration" rel="nofollow ugc">GitHub-Repo</a> for details.

ReCaptcha Integration for WordPress

This plugin is very robust. It replaces another reCAPTCHA plugin I was using. I like this one because it works with WooCommerce, and protects login, lost password, and commenting forms.

Very Robust. Easy To Setup

This was the only plugin I could find that added a Captcha to the WooCommerce guest checkout. All the others either need to be paid for or only add a captcha to the login and registration pages. I wish this plugin was more visible so I hadn't wasted time with inferior offerings.

Nice job weDevs and thanks!

Protect your Contact Form 7 forms with Google reCAPTCHA V2, Google reCAPTCHA V3, hCAPTCHA, or Cloudflare Turnstile.
Easy integration and supports multiple forms on a single page.
<h3>Four CAPTCHA Options</h3>
Choose the CAPTCHA provider that works best for you:
<ul>
<li>Google reCAPTCHA V2 — The industry-standard “I’m not a robot” checkbox, trusted by millions of sites.</li>
<li>Google reCAPTCHA V3 — The industry-standard invisible score-based verification, trusted by millions of sites.</li>
<li>hCAPTCHA — A privacy-first alternative that offers robust bot protection while keeping user data secure.</li>
<li>Cloudflare Turnstile — A modern CAPTCHA that verifies users in the background, only requiring a simple click if the visitor appears suspicious.</li>
</ul>
<h3>Simple Setup</h3>
<ol>
<li>Sign up with your chosen CAPTCHA provider and grab your Site Key and Secret Key.</li>
<li>Paste them into CF7 Captcha in your WordPress admin.</li>
<li>Add protection to any CF7 form in seconds using the shortcode provided in the same settings page.</li>
</ol>
<h3>Customizable Appearance</h3>
Each CAPTCHA widget supports customization options directly from the shortcode:
<ul>
<li>Size — Choose between normal and compact to fit your form layout.</li>
<li>Theme — Switch between light and dark themes (or auto for Turnstile) to match your site’s design.</li>
<li>Language — Force any CAPTCHA to render in a specific language for your audience.</li>
</ul>
All options are combinable, so you can mix and match to get the exact look you need.
<h3>Submission Insights (NEW in v0.1.7)</h3>
Go beyond just blocking spam. Submission Insights gives you full visibility into every form submission:
<ul>
<li>Sender IP — See the IP address of the person who contacted you.</li>
<li>Source Page — Know exactly which page on your site the form was filled out on.</li>
<li>Device & Browser — Get technical details about the sender’s setup.</li>
</ul>
<h3>🚀 Want More? Upgrade to CF7 Captcha Pro</h3>
This free version gives you solid CAPTCHA protection. But the smartest bots are already solving CAPTCHAs.
CF7 Captcha Pro adds six extra layers of invisible spam defense on top of what you already have here, plus a full set of tools to capture and act on every lead your forms collect.
<h3>What you get with Pro</h3>
6-Layer Spam Defense — stops 99.9% of spam without ever bothering your visitors: 
– Advanced Honeypot — invisible trap fields with names that regenerate every 24 hours. 
– Time Limit Validation — bots submit in 0.2 seconds. Humans take 15–30. This blocks anything that moves too fast (or stays too long). 
– Rate Limiting — caps submissions per IP so bot networks can’t flood your inbox or burn through your email quota. 
– Geographic Blocking — whitelist only the countries you serve, or blacklist known spam regions. 
– IP Pattern Blocking — block single IPs, wildcards, CIDR ranges, or entire subnets when you know exactly where an attack is coming from. 
– Word Filter — scans every submission for spam keywords, phishing URLs, and known scam phrases before it reaches you.
Lead Recovery — 70% of people who start filling out a form never submit it. Pro captures their data in real-time as they type, so you can follow up on leads that would otherwise vanish.
Database Storage & Export — every submission is saved with full metadata (IP, browser, referrer, timestamp). Export to CSV, Excel, JSON, or PDF whenever you need it. No more lost leads if your email fails.
Webhooks — send form data instantly to any URL. Connect to Zapier, Salesforce, Slack, Google Sheets, or any custom API. Multiple webhooks per form, with retry logic built in.
Mailchimp Integration — submissions automatically added to your Mailchimp lists. Field mapping, tags, opt-in handling.
Twilio SMS — receive instant alerts for every submission or send automated SMS replies to your clients.
Comprehensive Logging — every spam block, webhook call, and integration event is logged. Debug any issue in minutes instead of hours.
