Extensiv Integration Manager strives to support as many shopping carts and marketplaces as possible, but we can't support everything. If you need Integration Manager to connect to a cart or marketplace we don't yet support, here's what you should do:
Reach out to Integration Manager Support
Integration Manager can accept almost any CSV format for loading orders. If you can export orders in CSV format from your system, Integration Manager can probably accept them. This can be done either manually or automated via FTP.
Documentation on CSV Formats is available here: CSV Files
Let is know if you need help setting it up in Integration Manager or mapping your custom CSV file format.
The Integration Manager API allows you to integrate directly with Integration Manager in a highly robust and automated fashion. If you have some technical talent on your team, this is the best way to go.
