This is the data synchronization that happens when a new business is connected for the first time. Under the 'Integrations' -> 'Data Sync' option, you can choose the data types that you wish to synchronize initially, along with the number of years to sync:

These data types which are synchronized initially, can be retrieved through the Railz API endpoints after successfully connecting a business. The deselected data types under 'Data Sync', will be synchronized in the next sync process and will be available after that. Please note that, for Enterprise plans, the 'Data Sync' settings can be set at a team level for all businesses and service providers and only Super Admins can change these settings. You may find more information about Data Sync settings here.

Here's a short video of using the 'Data Sync' settings for Initial Data Synchronization:

Please refer this page for more details on Initial Data Synchronization.

Railz synchronizes all connections every 24 hours from the connection date and retrieves all new transactions since the previous sync. For additional information, please visit this page.

We have a dedicated endpoint POST /data/sync to initiate an on-demand data sync for any specific data type. You may find more information here.
