[Treasury Prime docs]: creating a transfer returns pending. The terminal states are sent (funds available in the destination), error (check the error field), or canceled. Monitor through the Console Transactions tab, the network_transfer.create and network_transfer.update webhooks, or polling. In production start with a low-value test transfer between accounts you control to confirm estimated_settlement_at reflects the next banking business day. Simulation calls only work against sandbox: they fail against a production client.

Context: Network transfers settle asynchronously. Check status, not the create response.
