      }

## Error Codes

| Status Code | Description                        |
| ----------- | ---------------------------------- |
| 200         | Item removed successfully          |
| 400         | Invalid user ID or request body    |
| 401         | Unauthorized access                |
| 500         | Server error - Failed to sync cart |

## Important Notes

<Warning>
  The sync endpoint replaces ALL cart items. To remove an item, send a request with all items you want to KEEP, excluding the one(s) you want to remove.
</Warning>

<Info>
  Removal workflow:

  1. Fetch the current cart using GET `/api/cart/:userId`
  2. Filter out the item(s) you want to remove from the items array
  3. Send the remaining items back to the sync endpoint
</Info>

## Removal Strategies

**Remove by exclusion**: The recommended approach is to exclude items you want to remove from the items array

**Clear cart**: Send an empty items array to remove all items at once

**Validation**: Only valid, non-deleted products are kept in the cart. Invalid product IDs are automatically filtered out

**Side effects**: The `abandonedEmailSent` flag is reset to `false` when cart contents change
