# CKSyncEngine.Event.willSendChanges(_:)

The sync engine is about to send changes to the server.

```
case willSendChanges(CKSyncEngine.Event.WillSendChanges)
```

## Discussion

A send operation may send all local changes, only changes to a specific set of records, or only those in a specific record zone. Use this case’s associated value to determine the scope for the current operation. For more information, see [`CKSyncEngine.SendChangesContext`](/documentation/CloudKit/CKSyncEngine-5sie5/SendChangesContext).
