Oplog runs the warehouse, not you — and that is what the connection means
Oplog is not a carrier but a fulfilment service: your products sit in their warehouse, and when an order arrives they pick, pack and ship it. The connection is shaped accordingly — order information goes from Stokzone to Oplog, and stock and shipment status come back from Oplog to Stokzone.
Setup takes two values: a tenant identifier and a static token, both issued from the OpenAPI setup screen in the Oplog panel. If you will work against the test environment, remember the credentials are separate from production; a staging token does not work against live.
