SEDNA

SEDNA is the operating system for shipping — a communications and workflow platform that unifies email, voyage and trade operations, and document handling for maritime, commodity trading and logistics teams. Its API (version 2019-01-01) exposes messages, contacts, teams, users, job references, category tags, events and workflows over a JSON:API-style REST interface secured with OAuth 2.0 client-credentials, letting developers automate inbox routing, tagging, subscriptions and third-party integrations. Backed by Insight Partners.

SEDNA publishes 17 APIs on the APIs.io network, including Authentication API, Category Tag API API, Comment API API, and 14 more. Tagged areas include Company, Shipping, Maritime, Email, and Communications.

SEDNA’s developer surface includes documentation, API reference, support, engineering blog, authentication, and 20 more developer resources.
