Set up risk rules and block lists
Short answer
Under Risk, add a rule that blocks a payment or asks for a review, or put an email address, a domain or an IP address on your allow or block list.In this article
Add a rule
- Open Risk, then Rules.
- Under New rule, give it a Name that says what it does.
- Choose what it tests under When, a Comparison and a Value.
- Under Then, choose Take the payment and ask me to review it or Refuse the payment.
- Press Create rule.
A rule tests one thing. It cannot be edited afterwards, so to change one, press Switch off and make another.
Two examples
| To | When | Comparison | Value | Then |
|---|---|---|---|---|
| Look at anything over BZ$2,000 | Amount (minor units) | is at least | 200000 | Review |
| Refuse a domain you have had trouble with | Email domain | is | example.com | Refuse |
Amounts are in minor units, so 200000 is 2,000.00. A rule compares the amount in the payment’s own currency, so this one also catches US$2,000.
Allow and block lists
Under Lists, choose Block or Allow, then an Email address, Email domain or IP address, and press Add. A note helps you remember why.
- Allow is checked first and wins over every rule, ours included.
- Block refuses the payment before the bank is asked.
A Saved card fingerprint only works on charges against a card a customer has saved. It cannot stop the same card being typed again.
Test and live
Your rules and lists belong to the mode you made them in. Make them again in Live to protect real payments.
