Zaius

Zaius is the B2C marketing customer data platform (CDP) that Optimizely acquired in 2021 and now operates as the Optimizely Data Platform (ODP). It unifies customer, event, order, product, and custom data into a single behavioral profile, powers real-time audience segmentation, and drives personalization and orchestrated cross-channel campaigns. ODP exposes a versioned (v3) REST API surface across regional hosts (US/EU/AU) for events, customers, orders, products, objects, lists, consent, exports, schema management, recommendations, and real-time segments, plus a GraphQL query API and Web / React Native / Node SDKs. Authentication is via public (Tracker ID) and private x-api-key keys. Originally a portfolio company of Insight Partners.

Zaius publishes 17 APIs on the APIs.io network, including Compliance API, Consent API, Consent (Legacy) API, and 14 more. Tagged areas include Company, Customer Data Platform, CDP, Marketing, and Personalization.

Zaius’ developer surface includes documentation, API reference, getting-started guide, support, engineering blog, pricing, signup flow, and 31 more developer resources.
