Recaptcha is a free service powered by Google that protects your website from attacks and abuses from automated bots. Starting with Miva Merchant 9.53, we've added integrated support of the Recaptcha service making it easy to set up right from your Miva Merchant Admin should you choose to use it. Enabling Recaptcha in your Miva Merchant Store adds an extra layer of protection to your checkout process to help verify that your website is being visited by an actual Shopper looking to buy your products and not a malicious bot attempting to exploit your web store to validate stolen credit card numbers. Modern Recaptchas are pretty unintrusive to your Shopper and look something like this, requiring your Shoppers merely to click on a single checkbox to confirm they aren't a robot. To use Recaptcha in your store, you'll first need to visit google.com/recaptcha and sign up for a Google account if you don’t have one already. Login and add your stores domain to your Google account and be sure to copy down two pieces of information; the site key and the secret key. Once you have that squared away, log into your Miva Merchant Store Admin and click into “Payment Settings” and then click into the Settings tab. Here you will see a section called “Recaptcha.” By default, the Recaptcha feature is set to “Off.” Setting the Recaptcha mode to “On” makes it so that every checkout process will include a Recaptcha prompt during checkout. You also have the option to reset the Recaptcha mode to “Velocity.” If your Recaptcha mode is configured like so, your online shoppers will generally never see a Recaptcha prompt during checkout. Your store will only require validation if it detects at least 10 failed credit card authorization attempts within a one-hour window. During this heightened number of failed attempts, all check out processes will require Recaptchas. After the number of failed attempts drop back down to below 10 within one hour, your store goes back to not requiring Recaptcha.
The theme setting helps make the Recaptcha box fit your websites look and feel. If your design is lighter, you'll probably want to set this to light. If you have darker colors more prominent, than the dark setting maybe more appropriate. Google completely re-imagined their Recaptcha service for the most part interacting with a Recaptcha is as simple as checking a checkbox stating that you're not a robot, but Google is also calculating algorithms behind the scenes and if Google senses that a website visitor might be an automated program, the Recaptcha further asks the visitor to validate themselves through a slightly more involving inquiry. In these situations setting type to audio would display a distorted text to the visitor which they would then have to type into a text box. There is a button that they can click on so they could audibly hear it the letters in the event that the text is too distorted to read. If you set type to “Image,” the visitor would be shown a collection of images and asked to click all images that match a test image.
Moving on, you can choose to make the recapture standard size or slightly smaller and you can choose the language the Recaptcha box displays in. Next, you will see a text field for public key. This where you want to paste in the Site Key that you copied from Google. And the private key fields are where you want to paste in the Secret Key that you got from Google. Finally, you can choose to automatically disable Recaptcha for any orders that are free. Once you've configured this section the way you want, be sure to click on the update button on top to save your configuration and you'll be set to use Recaptcha in your store.
