What is a freight API and how does FreightPOP’s work?

A freight API lets your systems communicate directly with carriers and a TMS to automate shipping tasks. FreightPOP’s unified API connects to parcel, LTL, FTL, ocean, rail, and international air so you can rate, book, track, and audit shipments from one endpoint pattern.

Which shipping modes and carriers are supported?

FreightPOP supports parcel, LTL, FTL, ocean, rail, and international air across a large, continually growing carrier network. You can start with core carriers and add more without rebuilding integrations.

Can I compare rates across multiple carriers in real time?

Yes. The API returns multi-carrier rates side-by-side with service levels, transit times, and accessorials so you can select the best option programmatically or via business rules.

Does the API support booking, labels, and documents?

Yes. You can create shipments, book pickups, generate labels and documents (BOL, commercial invoice, packing list), and retrieve them via direct links or base64 payloads depending on the carrier.

How do I track shipments and get status updates?

Use tracking endpoints for real-time milestones and delivery exceptions. You can also subscribe to webhooks for push notifications when statuses change, eliminating the need for constant polling.

Do you offer a sandbox and sample code?

Yes. A free sandbox with realistic carrier responses is available, plus Postman collections and SDK examples to accelerate implementation.

How is authentication handled and are there rate limits?

Authentication uses scoped API keys with optional OAuth2 for enterprise deployments. Reasonable per-key rate limits protect platform stability, and higher limits are available upon request.

Can the API integrate with our ERP, WMS, or eCommerce platform?

Yes. FreightPOP provides native connectors and a flexible API to integrate with common ERPs, WMS systems, and eCommerce platforms, mapping order, item, and shipment data both ways.

How does pricing work for API access?

API access is included with platform subscriptions. Usage tiers are based on shipment volume and features enabled (e.g., webhooks, advanced analytics). Contact us for a plan aligned to your volume.

What about security, compliance, and data privacy?

FreightPOP uses encrypted transport (TLS), at-rest encryption for sensitive data, role-based access controls, and audit logging. Data residency and retention policies can be configured to meet your compliance needs.

Do you support international shipping and customs documents?

Yes. The API supports HTS codes, Incoterms, country-of-origin, and generates customs paperwork for international shipments where supported by carriers.

How are versions, SLAs, and uptime handled?

The API is versioned with deprecation timelines and change logs. FreightPOP provides enterprise-grade SLAs and status visibility for uptime and incident communications.

FreightPOP’s Unified Freight API vs. Alternatives

Connectivity, effort, visibility, and total cost of ownership

Aspect	FreightPOP’s Unified Freight API	Individual Carrier APIs / Legacy Systems
Carrier ConnectivityParcel, LTL, FTL, international	Hundreds of carriers integrated out-of-the-box. Add new carriers without custom builds.	Limited coverage; each carrier requires a separate integration.
Implementation EffortSpeed to value	One integration to connect ERP/WMS/eCommerce to all carriers; pre-built connectors accelerate go-live.	Multiple one-off builds; ongoing maintenance for every carrier API.
FunctionalityEnd-to-end workflow	Full TMS: instant rates, booking, labels, tracking, and invoice audit—configurable rules across modes.	Capabilities vary by carrier; no unified cross-carrier workflow.
Data VisibilityControl & reporting	Single dashboard with real-time cross-carrier tracking and analytics (spend, performance, on-time rates).	Fragmented data across portals; manual aggregation required.
Scalability & SupportGrowth-ready	Scales with volume, locations, and carriers; expert onboarding and ongoing support.	Scaling strains custom integrations; support split across vendors or in-house only.
Cost ImpactTotal cost of ownership	Lower ship costs via competitive rate shopping; reduced IT maintenance.	Higher ship/IT costs and upkeep across many integrations.
