A Shopify 3PL integration should make it clear which warehouse receives each item, when it may start work and how Shopify learns what happened. Agree the stock and order rules before switching on automatic fulfillment. Then test cancellations, partial shipments and recovery as well as a successful order.

1. Connection and owners
Record the app or email workflow, connector maintainer, warehouse contact, current supported API version and required access.

2. Product and location mapping
Match Shopify variant/SKU, warehouse item, pack size, location and product activation.
