Automate port drayage dispatch and terminal gate appointment booking via a drayage TMS API

Steps

1. Select a drayage TMS with an open API (such as PortPro or DrayMate) and obtain API credentials; confirm that the TMS integrates with the specific marine terminal appointment system at the port you are targeting.
2. Create a dispatch order via the TMS API by supplying container number, terminal, last free day, appointment window preference, chassis type, and trucker assignment.
3. Poll the TMS API for appointment confirmation status; the TMS interfaces with the terminal appointment system (e.g., APMT Pier Pass, GCT, or TRAPAC portal) and returns the confirmed gate appointment slot.
4. Monitor for terminal holds via the TMS API: freight holds, customs holds, and terminal demurrage flags must be resolved before the gate appointment will be honoured.
5. Receive dispatch event webhooks from the TMS as the driver checks in at the gate, completes the interchange inspection, and departs; use these events to update your import tracking system.
6. Automate last-free-day alerts by subscribing to container availability and demurrage accrual events from the TMS; flag any container approaching its LFD without a confirmed appointment.
