Radial has an official API, but teams routinely hit its limits: gated access, partial coverage, or paid tiers. Most end up supplementing it with exports or an unofficial API layer like Supergood.
Radial is an enterprise third-party logistics (3PL) and commerce technology provider that combines an owned-and-operated network of 30+ fulfillment centers across North America and Europe with a software stack covering order management, payment processing, fraud prevention, tax compliance, returns management, and store/dropship fulfillment.
Primary vertical: Fleet / Trucking / Logistics, specifically the enterprise ecommerce fulfillment / outsourced-3PL segment serving mid-market and Fortune 500 brands. An enterprise retailer integrates Radial into its order management and storefront stack, either through a pre-built connector (Shopify, Adobe Commerce/Magento, Salesforce Commerce Cloud, NetSuite), the Radial REST APIs, or EDI, and ships inventory into one or more Radial fulfillment centers (often FTZ-enabled for duty deferral on imported goods).
High inside the enterprise 3PL niche. Radial is one of the most-recognized enterprise fulfillment partners in North America, ships 18M+ units during peak, operates 30+ fulfillment centers, and was acquired by bpost for $820M in 2017.
For merchants on Radial, the API and Customer Portal are the system of record for order routing and fulfillment status across DCs, inventory by SKU and by location, payment authorization and settlement, fraud disposition (approve/decline/review), tax calculation, returns lifecycle, and monthly fulfillment + payments + fraud + tax invoicing, all of which feed directly into storefront accuracy, customer service tickets, marketplace SLA compliance, retailer chargeback exposure, and revenue recognition.
Radial's lineage traces back to GSI Commerce (founded 1986, acquired by eBay for $2.4B in 2011), spun back out as Radial in 2015 under Sterling Partners and Innotrac, then acquired by bpost in 2017 for $820M, making the underlying technology stack ~30 years old in its oldest layers.
Grades measure one thing: can a customer's engineering team get their own data out programmatically? We check six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and roll them into a letter grade. Grades get re-verified, and they only move on evidence.
Yes. Supergood maintains an unofficial Radial API and MCP server so AI agents and internal tools can read and write Radial data. See the Radial integration docs at supergood.ai/docs/radial-api.
