ShipStation Auto-Run is not added yet to automate the continuous exchange of orders.
ShipStation Orders will run batches to invoice at end of day and reconcile shipments.
To process, import Customers, then import Invoices, then repeat Customers to check. ShipStation allows a maximum of 200 orders per batch including Redacted or Return.
Exclude Code let you set a Prefix to ignore when automatically matching. Some users and companies put ZZ in front of the Listing of Customers that are no longer useable.
For Folder Connect, to import custom files, go to Folder Settings and click Advanced. In the Exclude Code field enter the code you put before defunct customers, such as zz.
This feature is for convenience. Setting Customers as Inactive is an option to consider.
