REST API for the Solsten assessment and persona platform. Documented operations cover listing users who completed an assessment (paged, 500 per page, one-hour cache), checking a single user's assessment status, reading assessment metadata and completion statistics, permanently deleting a user's data on request, and fetching the user IDs that belong to a segment/persona. A PlayFab webhook endpoint accepts inbound gameplay events. Authentication is a Bearer API key issued per dashboard. No OpenAPI or other machine-readable contract is published.
