Handling This Event

When you receive an event.item_updated webhook, fetch the current item data from the API using data.id (the event feed item identifier):

async function handleEventUpdated(feedId: string, itemId: string) {
  // GET /feeds/events/{feedId}/items/{itemId}
  const event = await helixApi.getFeedItem(feedId, itemId);

  // Update your local copy
  await database.events.update({
    where: { helixEventFeedItemId: itemId },
    data: mapToLocalEvent(event),
  });
}

Important

The webhook payload is intentionally minimal. Always fetch the current event state from the API rather than relying on cached data. This ensures you have the most up-to-date information.
