## Collection Schema

The plugin creates a notifications collection with the following fields:

- **title** (required text): The notification title
- **message** (required richText): The notification content
- **recipient** (optional relationship): User who should receive the notification (optional if using custom recipient fields)
- **isRead** (checkbox): Read status tracking
- **readAt** (date): When the notification was read
- **attachments** (group): Configurable relationship fields
- **createdAt/updatedAt**: Automatic timestamps

## API Usage

### Creating Notifications

```typescript
const notification = await payload.create({
  collection: 'notifications',
  data: {
    title: 'Order Shipped',
    message: [
      {
        children: [
          { text: 'Your order has been shipped and is on its way!' }
        ]
      }
    ],
    recipient: userId,
    attachments: {
      order: orderId,
      product: productId
    }
  }
})
```

### Querying Notifications

```typescript
// Get unread notifications for a user
const unreadNotifications = await payload.find({
  collection: 'notifications',
  where: {
    and: [
      { recipient: { equals: userId } },
      { isRead: { equals: false } }
    ]
  },
  sort: '-createdAt'
})

// Mark notification as read
await payload.update({
  collection: 'notifications',
  id: notificationId,
  data: {
    isRead: true,
    readAt: new Date()
  }
})
```
