How to use Stripe Radar for fraud protection
In this help article, youβll learn what Stripe Radar is, how it works, and how to enable it to protect your business from fraudulent payments.
What is Stripe Radar?
Stripe Radar is a fraud prevention tool that uses machine learning and customizable rules to help you detect and block fraudulent payments.
With Stripe Radar, you can:
- Block payments when the CVC check fails.
- Block payments when the ZIP/AVS check does not match.
- Flag or block payments from suspicious IP addresses or countries.
- Use the risk score to decline high-risk charges automatically.
- Write custom rules to handle specific cases, such as blocking payments from disposable email addresses.
Fees and pricing
When using Stripe Radar, it is important to note that fees may vary depending on your Stripe account and location.
Basic fraud protection is included in Stripeβs standard pricing; however, advanced features may incur additional charges.
Since pricing policies are updated from time to time, we recommend checking Stripeβs official pricing page or contacting Stripe support directly for the most accurate and up-to-date details.
Configuring Stripe Radar rules
While Stripe's basic fraud detection is always active, you can add custom rules for more control.
These rules are managed directly in your Stripe account.
Create a Radar rule
To create a Radar rule, log in to your Stripe Dashboard.
From the menu, under Payments, go to Radar, then Rules. If you do not see this option, you may need to activate this feature for your Stripe account.
Add a rule type
Click Add rule and choose the type of rule that suits your needs, for example, Add block rule.
Enter the rule condition
Enter the condition you want to apply. For example, if you want to block payments over $5000 from customers who created their account less than 24 hours ago, you can use:
:amount_in_usd: > 5000 and :hours_since_customer_was_created: < 24Youβll find a ready-made rule like this in the list of examples when you scroll down in Stripe.
Test and enable the rule
Click Test rule to preview the impact of the rule before actually enabling it.
Lastly, click Add rule to enable it.
Important notes
- These settings must be configured directly in your Stripe account.
- SystemeScale cannot configure Radar rules for you.
- Enabling these rules is optional, but highly recommended if you want stricter control over fraudulent charges.
