How to integrate Shopify with Dokan using SyncSpider

Does this work for Dokan on BuddyBoss? And if so, does this only import and export products on the right accounts?

For instance, I have Vendor A, Vendor B and Vendor C… each vendor has their own store and are separate businesses from each other.

Does A’s Dokan account only receive products from A’s Shopify? And B’s Dokan account from B’s Shopify? And C’s Dokan from C’s Shopify?

Does this integration know what account to send products to without adding products from one Vendor’s account to another’s account?
