Embed logistics into your stack.
Circuit 43 gives enterprise systems and logistics platforms embedded access to Circuit execution infrastructure: structured booking, shipment state, documents, webhooks, and operational handoffs through API-first integration.
// Create a new shipment booking
const shipment = await circuit.shipments.create({
corridor: "LHR-LOS",
slot_id: "SLOT-2026-05-22-A",
parcels: [{
reference: "PKG-91042",
weight_kg: 12.5,
declared_value: 350
}],
notify_url: "https://your-api/hooks/circuit"
})
// Response
// { id: "SHP-2026-04471", status: "confirmed", ... }The full operational surface, via API.
Everything a freight business, platform, or enterprise team needs to embed access to international execution workflows without rebuilding the coordination infrastructure from scratch.
Programmatic shipment creation
Create, confirm, and manage shipment requests directly from your system. Query corridor availability, shipment requirements, and execution options before committing.
Webhook event stream
Subscribe to shipment lifecycle events such as booking confirmed, status updated, documents requested, customs cleared, and delivered via signed HTTPS webhook.
Shipment state API
Poll shipment status on demand or embed tracking into customer-facing and internal operational surfaces. Events are timestamped and attributed.
Document retrieval
Retrieve receipts, customs documentation, and proof of delivery programmatically. All documents are attached to the canonical shipment record.
Operational data export
Export shipment records, document events, handoff history, and exceptions across time ranges or corridors for operational review and BI ingestion.
Slot and rate management
For operators using Circuit 43 with Circuit 44, manage departure slots, available corridors, service options, and execution constraints.
Integrates with the systems you already run.
Circuit 43 is designed to embed into existing freight operations stacks, customer portals, and platform workflows. Standard REST and webhook patterns let companies connect their ERP, WMS, TMS, or custom systems to Circuit execution infrastructure.
