Each entry has the instant, the source and target states, who caused the transition (`origin`: API, rail, STR, ledger, worker, operator, or system), the official reason, and the related identifier (for example, the `nuop` assigned at submission). Use it for audit, customer support ("what happened to TED X?"), and to debug integrations. For the current state, `GET /v1/transfers/{transferId}` is enough. ## OpenAPI ````yaml /en/openapi/v3-current/ted-lerian.yaml get /v1/transfers/{transferId}/timeline openapi: 3.1.0 info: description: >- API of **TED Lerian**, the interface over Lerian SPB.
