# Hull

**Canonical:** https://apis.io/providers/hull/  
**Website:** https://www.hull.io  
**APIs profiled:** 1

Hull is a real-time Customer Data Platform (CDP) that unifies customer data from every source — web, product, CRM, marketing and support tools, databases and files — into a single User and Account profile using claim-based identity resolution. It ingests, computes and enriches data through a data-lifecycle pipeline (Ingest / Compute / Notify), organizes people and companies into Segments, and syncs the resulting profiles out to more than fifty tools via Connectors ("ships"). Developers integrate through a flat HTTP API at https://{organization}.hullapp.io/api/v1 covering Users, Accounts, Events, Segments, Status and Bulk operations, plus first-party Node, browser, PHP and Ruby client libraries and an outgoing/incoming webhook surface. Hull was acquired by MessageBird (now Bird) and the platform was switched off at 09:00 ET on 31 December 2022, with all infrastructure decommissioned and customer data deleted; the marketing site and documentation remain published but the API host no longer answers.
