ShipStation API
ShipStation runs two parallel public REST APIs: V1 at ssapi.shipstation.com (Basic auth) and V2 at api.shipstation.com (API-Key header, built on ShipEngine). Free developer sandbox accounts are available, though production V1 access needs the Standard plan. Webhooks are first-class on both.

ShipStation is the dominant multi-channel ecommerce shipping platform in the Auctane portfolio.
Primary vertical: Fleet / Trucking / Logistics, specifically the multi-channel ecommerce shipping and fulfillment slice. A mid-market ecommerce retailer connects ShipStation to Shopify, Amazon, eBay, and Walmart via the built-in store connectors or via the V1 API's /orders endpoint.
Very high. ShipStation is one of the two or three default names in any ecommerce shipping RFP (alongside Shippo and EasyPost on the API side, and ShipBob/ShipHero on the 3PL/WMS side).
ShipStation is the system of record for inbound order normalization across every connected marketplace and store, the chosen carrier and service level for every outbound shipment, the printed label (which is a paid, irrevocable physical-mail artifact), the manifest submitted to each carrier at end-of-day, and the tracking events that drive customer-facing shipped/delivered notifications.
Founded in 2011 in Austin, Texas, ShipStation was acquired by Stamps.com in 2014, which then merged into Auctane in 2021 (now owned by Thoma Bravo).
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.
