# sync_completed

**The full sync is already complete.**

| | |
|---|---|
| HTTP status | `409` |
| `code` | `sync_completed` |
| Retry? | No, fix the request first |

## What it means

You sent a batch with a `sync_id`, or called `complete`, after the sync was already completed.

## How to fix it

Start a new sync for a new reconciliation. A repeated `complete` after a network error can be ignored: the first call succeeded.

## Example

```json
{
  "type": "https://docs.kalender-sync.de/en/api/errors/sync_completed",
  "title": "Conflict",
  "status": 409,
  "code": "sync_completed",
  "detail": "This sync is already complete.",
  "request_id": "req_…"
}
```
