Parameters

syncToken

Type: SystemString
The synchronization token provided by the remote storage dyring last sychronization event. Null in case of the initial synchronization call.

deep

Type: SystemBoolean
Indicates the "scope" of the synchronization report request, false - immediate children and true - all children at any depth.

limit

Type: SystemNullableInt64
The number of items to return. Null in case of no limit.

cancellationToken

Type: System.ThreadingCancellationToken
The token to monitor for cancellation requests.

Return Value

In this method you will request all changes from your remote storage passing the provided syncToken. The remote storage must return all changes that happend after the provided syncToken and a new sync-token. You will return all changes and a new sync-token to the Engine. The Engine will process all changes and save a new sync-token.

Any items that failed to process, for example because an item was blocked, will be marked as a conflict.
