 QuickBooks updates are sparse: provide the record ID, its current `SyncToken`, and only the fields you want to change. Use the latest `SyncToken` returned by a read or mutation.

Create actions accept an optional `requestId` that QuickBooks uses for idempotency when the same request may be submitted again.
