The Yandex SmartCaptcha add-on for CS-Cart and Multi-Vendor isn’t just a bot protection. It’s a way to stop losing money to spam and avoid annoying real people with captchas.

How it works

You install and configure the add-on and your site automatically distinguishes between real people and bots.
A customer logs in, places an order, and registers—without any unnecessary clicks or “prove you’re not a robot.”

Bots are filtered out.

What are the benefits?

1. Less spam—more order

Contact, registration, and order forms are no longer cluttered with junk. Managers work with real requests, not cleaning out emails.

2. You don’t lose customers to captchas
Regular captchas are annoying: you have to enter something, select images, and waste time.
SmartCaptcha runs in the background—the user barely notices it.

3. Quick and painless installation
Install the module, insert the keys, and that’s it. No need to rewrite templates or mess with code.

4. CS-Cart and Multi-Vendor support
Works in both regular stores and marketplaces with vendors. Protection is provided for all storefronts.

5. Adapted to real people
If the system is sure it’s a human, it won’t show any tasks. If it’s unsure, it runs a simple check.

What is the advantage vs google captcha (which can I believe also be set to invisible?) ?

Is it compatible with GDPR as in no data like the customers IP address is being sent to 3rd parties, etc?

Does this need a subscription or registration with Yandex?

Thanks!

Greetings, flow!

Our add-on offers an alternative to Google reCaptcha, this is actual right now to users of some countries that are restricted by Google in certain ways to use their services. Other than that, it is similar to Google reCaptcha.

Please see this article.

No, it doesn’t.

Update 1.4: the captcha is drawn when the customer turns to the form

We have released version 1.4 of the Yandex SmartCaptcha Anti-Spam add-on. The main change is the moment the widget appears on the page.

Before, the “I’m not a robot” widget was built on page load in every form at once, including the forms hidden until a click: the call request window, sign-in, one-click purchase. Now it is drawn when the customer opens the form or starts filling it in. That gives three things:

  • Safari on iPhone. With “Prevent Cross-Site Tracking” on, the browser grants the widget storage access only in response to a visitor action. A widget built on page load could not pass the check. Now it does.
  • Pop-up windows. In the call request window the widget was built in a container of zero width and stayed inoperable after the window opened. Now it is built after the window opens and fits in it entirely.
  • Speed. A page where the visitor never turns to a form does not load the widget at all.

Version 1.3 ships to customers together with 1.4: the widget is no longer cut off at the bottom in themes that limited the container height, and after a failed AJAX submission the widget resets itself, so the next attempt does not hit a spent token.

The add-on page and the manual were rewritten as well: modes per form (visible, invisible, off), keys and the connection check, excluded countries with the stock captcha, several storefronts. The links to the live demo and the documentation are on the add-on page in the Marketplace:

The update arrives through the Add-ons Manager; settings and keys are kept. After the update the widget appears on a form after a click into a field - that is the expected behaviour.
