QuickBooks Change Data Capture API
The change data capture (cdc) operation returns a list of objects that have changed since a specified time. This operation is for an app that periodically polls data services in order to refresh its local copy of object data. The app calls the cdc operation, specifying a comma separated list of object types and a date-time stamp specifying how far to look back. Data services returns all objects specified by entityList that have changed since the specified date-time. Look-back time can be up to 30 days.
