Send transaction events to CirclesCheck for risk scoring. Flagged transactions create alerts and can emit webhooks for automated controls.

Example request

curl -X POST 'https://api.circlescheck.com/api/v1/transactions' \
  -H 'Authorization: Bearer cc_live_your_api_key' \
  -H 'Content-Type: application/json' \
  -d '{
    "customerId": "cus_abc123",
    "type": "card_payment",
    "amount": 12500.00,
    "currency": "USD",
    "country": "US",
    "externalId": "txn_12345"
  }'

When a transaction is flagged, CirclesCheck creates an alert and can send a transaction.flagged webhook event to your endpoint.

Alerts are reviewable in the dashboard and can be acknowledged, escalated, or dismissed.
