​
Fraud detection & risk assessment

  • Type: PRE_TRANSACTION

  • Scenario:

    • Before approving a transaction, a pre-transaction hook triggers an external fraud detection system.
    • The fraud detection system analyzes transaction patterns and generates a risk score.
    • If the risk score exceeds a predetermined threshold, the transaction is either flagged for manual review or automatically rejected.

  • Benefit: This process minimizes fraudulent transactions while ensuring legitimate transactions are unaffected.

​
Customer due diligence & KYC checks

  • Type: PRE_TRANSACTION

  • Scenario:

    • When a high-value transaction is initiated, a pre-transaction hook activates an external identity verification system.
    • The system provides verification details, such as KYC compliance status and risk category.
    • If the user is not verified, the transaction is halted, and a manual review is initiated.

  • Benefit: This ensures regulatory compliance and prevents fraudulent transactions.

​
Dynamic transaction enrichment

  • Type: PRE_TRANSACTION

  • Scenario:

    • A pre-transaction hook retrieves additional metadata for a transaction before it is processed.

    • For example, it enhances payment transactions with geolocation data or customer segmentation tags.

    • This can be achieved by calling a metadata enrichment endpoint, such as:

      curl -X POST YOUR_BLNK_INSTANCE_URL/<id>/metadata \
-H "Content-Type: application/json" \
-d '{
  "meta_data": {
    "last_name": "Brooks",
    "verification_status": "Pending"
  }
}'

  • Benefit: Enhances transaction data without altering the core system logic.

​
Loyalty points & rewards processing

  • Type: POST_TRANSACTION

  • Scenario:

    • After a successful transaction, a post-transaction hook triggers a loyalty system to award reward points.
    • The system updates the user’s loyalty points based on the transaction value.
    • If the user reaches a milestone, an automated reward is triggered.

  • Benefit: Ensures financial accuracy and prevents mismatches.

​
Real-time reconciliation & settlement

  • Type: POST_TRANSACTION

  • Scenario:

    • A post-transaction hook sends transaction details to an external reconciliation service.
    • The system cross-checks balances, payments, and pending transactions.
    • Any discrepancies trigger alerts for manual intervention.

  • Benefit: Ensures financial accuracy and prevents mismatches.
