## init(syncToken:paginationToken:)

Initialization method for the SyncStack.

The syncToken from the previous syncronization.

The paginationToken to fetch next batch of data.

You can use the sync\_token later to perform subsequent sync, which fetches only new changes through delta updates.

If there are more than 100 records, you get a pagination\_token in response. This token can be used to fetch the next batch of data.

The total number of resources which matched the original request.
