Risk Conditions

Configure fraud prevention rules and risk parameters in the Yuno Dashboard

Overview

Risk Conditions allow you to define rules that evaluate transactions for potential fraud before they reach the payment provider. Rules can block, flag, or require additional verification for suspicious transactions.

How Risk Evaluation Works

Yuno evaluates risk conditions in real time during payment creation. The risk decision is applied before the transaction is sent to the provider.

Creating Risk Conditions

1. Navigate to Risk Conditions

   Go to Dashboard > Risk Conditions and click Create Condition.

2. Define the trigger

   Select the attributes to evaluate:

   Attribute	Description	Examples
   Amount	Transaction value thresholds	Block if amount > $5,000
   Country	Origin or destination country	Flag if country = high-risk list
   Card BIN	Card issuer identification	Block specific BIN ranges
   Email	Customer email patterns	Flag disposable email domains
   Velocity	Transaction frequency	Block if > 5 attempts in 1 hour
   Device	Device fingerprint data	Flag new devices
   IP Address	Geolocation and proxy detection	Block VPN/proxy IPs

3. Set the action

   Choose what happens when the condition matches:

   Action	Effect
   Block	Immediately decline the transaction
   Flag	Process but mark for manual review
   3DS Challenge	Force 3DS authentication
   Allow	Explicitly allow (override other conditions)

4. Set priority and activate

   Assign a priority (higher priority conditions are evaluated first) and toggle to Active.

Common Risk Rules

High-value transaction blocking

Block transactions above a threshold to prevent large fraudulent charges:

Condition: amount > 10000
Action: Block
Message: "Transaction exceeds maximum allowed amount"

Velocity limiting

Prevent rapid repeated attempts from the same customer:

Condition: same customer_email AND count > 5 in last 1 hour
Action: Block
Message: "Too many payment attempts"

Geographic restrictions

Flag or block transactions from unexpected countries:

Condition: customer_country NOT IN [BR, CO, MX, CL, PE]
Action: Flag for review

BIN-based rules

Apply rules based on card issuer for known fraud patterns:

Condition: card_bin IN [blocked_bin_list]
Action: Block

Manual Review Queue

Transactions flagged by risk conditions appear in Dashboard > Risk > Review Queue. Reviewers can:

• Approve: Release the payment for processing
• Decline: Cancel the transaction
• Escalate: Forward to a senior reviewer

Configure notification alerts in Settings > Notifications to receive emails when flagged transactions enter the review queue.

Risk Analytics

Monitor fraud prevention performance in Dashboard > Risk > Analytics:

Metric	Description
Block rate	Percentage of transactions blocked
Flag rate	Percentage flagged for review
False positive rate	Legitimate transactions incorrectly blocked
Fraud detection rate	Fraudulent transactions caught

Overly aggressive risk rules can block legitimate customers. Monitor false positive rates and adjust thresholds regularly. Start with flagging (manual review) before enabling automatic blocking.
