QuickBooks SDK QBFC Com component to fetch deleted records in C#

Question

How to fetch only the modified and deleted records from the Quickbook using QBFC COM component in c#.

Answer 1

Each individual entity type has it's own modified date filter. For example, the CustomerQuery has the ORCustomerListQuery.CustomerListFilter.FromModifiedDate and ORCustomerListQuery.CustomerListFilter.ToModifiedDate. You'll find this pattern in the query message for every entity type and every transaction type.

For deleted records use the ListDeletedQuery for entities and TxnDeletedQuery for transactions.
