The raw Field

Every activity includes the original unmodified payload from the platform in raw. Use it when you need platform-specific data that isn’t covered by the normalized fields: 
SBCanvas.activities.on('subscribe', (a) => {
  // Access Kick-specific fields not in the normalized schema
  const kickBadges = a.raw?.badges;
  console.log('Raw platform data:', a.raw);
});
