React to the decision

Listen for fraudengine:ready to act on the risk decision in your application.

Handle the result

window.addEventListener('fraudengine:ready', (e) => {
  const { decision, score, reasons } = e.detail;

  if (decision === 'block') {
    // halt the application flow
  }
  if (decision === 'review') {
    // route to manual underwriting queue
  }
});
