The best build
on Abstract

Spammy signs up were an issue for us for a while, and we struggled to come up with the best way to identify all the variations in bad emails we were getting. Thankfully we found and quickly integrated with Abstract's email validation API, which saved us a bunch of time and gave us peace of mind.

Frequently asked questions

What is chargeback prevention?

Chargeback prevention is stopping fraudulent or high-risk orders before they turn into a chargeback. You score each order at checkout using the email, phone, and IP behind it, then hold, review, or decline the risky ones. Preventing the bad order is far cheaper than fighting the chargeback after it lands.

What is friendly fraud?

Friendly fraud is when a real customer disputes a legitimate charge to get their money back while keeping the goods, sometimes by accident and sometimes on purpose. It is one of the most common chargeback types, and because the buyer is genuine, the signal is in the order details and history rather than an obvious fake identity.

How do you prevent chargebacks before they happen?

Screen the order before it settles. Check whether the email is disposable or high-risk, whether the phone is VOIP, and whether the IP is a VPN, proxy, or a country that does not match the billing address. Combine those flags into a risk score and hold or decline orders above your threshold.

Which data signals predict a chargeback?

The strongest signals are a disposable or high-risk email, a VOIP or mismatched phone, and an IP that is a VPN, proxy, or in a different country than the billing address. A mismatch between where the order says it is from and where the network says it is from is a classic pre-chargeback red flag.

Does chargeback screening block legitimate customers?

It should not, if you score instead of hard-blocking. Weight the signals, send medium-risk orders to manual review, and decline only the clearest cases. Tuning the threshold to your own risk tolerance keeps false declines low while still stopping the orders most likely to charge back.

What is the difference between chargeback prevention and management?

Prevention happens before the transaction settles: score the order and stop the risky ones. Management happens after a dispute is filed: gathering evidence and fighting or accepting it. Prevention is cheaper because it avoids the fee and lost product entirely; Abstract sits on the prevention side, scoring orders at checkout.

How does Abstract help prevent chargebacks?

Call Abstract's Email Reputation, Phone Validation, and IP Intelligence APIs when an order is placed. You get disposable-email, VOIP, and VPN/proxy flags plus IP-versus-billing country mismatch as clear true or false fields, so you can score the order and stop likely chargebacks before payment clears.
