Integrations

• Selling channels. Bring the channel and its external order ID into the customer order. Check that ID before confirming a draft.
• Warehouse operations. Supply actual allocated, picked, shipped, delivered and returned events with stable external IDs and product quantities.
• Carriers. Return label and tracking results against the submitted carrier label and operation key.
• Payment providers. Supply authorization, capture, refund and void evidence with event IDs and provider references.

Agree which system owns each external action and which message counts as its observed result. Retain operation keys and provider references on retries. Reconcile uncertain results by reading the connected system before sending a second execution. Test duplicate and delayed events with a real pilot order. Review the implementation plan before connecting production accounts.
