Radial API
Radial is an ecommerce fulfillment and commerce technology provider that runs DTC order fulfillment, returns management, B2B distribution, transportation, payments, fraud prevention, and tax compliance for retail brands. An unofficial API lets you programmatically pull orders, inventory, shipments, returns, and tracking—and push updates like new orders, fulfillment requests, and inventory adjustments back into Radial across API, EDI, and pre-built cart connections.
What is Radial?
Radial is an ecommerce fulfillment and commerce technology provider (rebranding to Paxon) with 40+ years of operational experience and a nationwide fulfillment network that processes up to 18M units during peak. Retail brands use Radial to run direct-to-consumer order fulfillment, returns, B2B distribution, transportation and final-mile delivery, plus commerce services like payments, fraud prevention, and tax compliance—connecting their storefronts to Radial systems through pre-built cart integrations, EDI, and APIs.

The Radial Integration Challenge
Brands run mission-critical order and inventory operations through Radial, but turning its fulfillment platform into clean API-driven automation across every channel is non-trivial:
- Mixed connectivity models: Radial connects through pre-built cart integrations, EDI, and APIs—each brand's setup blends transports, so a single uniform interface rarely exists out of the box
- Per-merchant configuration: Order routing rules, SLAs, FTZ handling, and returns dispositions are tailored per brand, so generic integrations break across accounts
- Partner-gated onboarding: API and EDI access is provisioned through Radial implementation teams and partnership agreements before credentials are issued
- Authentication overhead: Credentialed sessions and rotating tokens complicate headless automation against fulfillment and commerce surfaces
- Spread across modules: Fulfillment, Transportation, Payments/Fraud/Tax, and Omnichannel each have their own object models, IDs, and event lifecycles
- Peak-volume scale: Brands need reliable, idempotent writes and timely status events even when Radial is processing millions of units during seasonal peaks
- Batch and file workflows: Inventory snapshots, shipment confirmations, and returns files often arrive as scheduled batches rather than real-time events
