GS1 EPCIS 2.0 REST API
The normative REST binding of the GS1 EPCIS 2.0 standard — the sector's supply chain visibility event interface, describing what happened to an object, when, where and why, using Core Business Vocabulary terms. GS1 publishes the contract (OpenAPI 3.0.3, 29 paths) rather than hosting a repository: capture (POST /capture), query (GET /events plus resource-scoped views by epc, bizStep, bizLocation, readPoint, disposition and eventType), named queries (POST /queries), and mandatory webhook subscriptions (POST /queries/{queryName}/subscriptions) where the client supplies a `dest` callback URL and a signatureToken the server echoes back in a GS1-Signature header. Implementers host their own base URL; the specification declares no `servers` block.
