Cart Block: checkout validator

Dealing with bots abandoning checkout because they are attempting different credit card numbers. This app allows me to set up rules to block these bots from checking out. They will still try but their attempts will be futile, so if they come across and use a card number that works, it will be blocked. In time they have slowed down as I believe it sees my store as not being able to do what they want.

It is working when you can identify bots as having similar profiles (in this case they all use the same fake address and phone area code) if bots change their strategy you have to find the commonality and set up another block.

Excellent app! We had BOTS card testing on our webstore and tried a few other apps that just didn't work. As of today, the BOTS are gone! Cart Block was simple to use and set up. We had minor issue at the beginning found out we had to update our checkout for this to work properly. Andrea was extremely helpful and was able to hop on a call with me. Thanks again! Looking forward to see what other apps you have to offer.

Support so far is exceptional. Let's hope this app works!

10/10 recommend this app - very functional and amazing customer service!

I had a very specific and niche use case, I emailed customer service and Andrea was not only very prompt to respond but even released an update to his app that would allow it to work for our use case. Thank you!

Love Cart Block app. This is by far the most versatile and flexible in terms of blocking rules.

Many apps promised email, address and phone number blocks but will require you to entre the exact value. Cart Block is the only app that offers "fuzzy block" rule where you can block checkouts containing certain values.

My store was hit by card testers, who were using my payment gateway to test stolen credit cards. With Cart Block app, it mitigated the risk with payment gateway. I tried many apps like Blockify, BoosterMark, Negate etc. None of them were as flexible as Cart Block.

When I reached out for support, Andrea replied promptly and implemented additional blocking parameters for me to use. This level of customer-centric approach plus the flexibility of the app means that I was able to ward off attempts at credit card fraud.

I will highly recommend this app to any merchants who experience card tester fraud issues, or anyone who requires product or geo blocking rules implemented at checkout.
