  title: Highlight Fullstack Session Correlation
  summary: Open a browser session, then emit a backend OTLP span tagged with that session id so frontend replay and backend trace correlate.
  description: >-
    Highlight stitches a frontend session replay to backend traces by sharing the
    session secure id as the highlight.session_id attribute on backend spans.
    This workflow performs that fullstack handshake: it runs the initializeSession
    GraphQL mutation against the public ingestion endpoint to open a session and
    obtain its secure id, then submits an OTLP span to the OTLP collector that
    carries highlight.session_id set to that secure id alongside the
    highlight.project_id. The OTLP export depends on the secure id minted by the
    session mutation, so the two specs are genuinely chained. Every step spells
    out its request inline so the flow can be read and executed without opening
    the underlying OpenAPI description.
