  version: "0"
  description: "Authentication only. This document describes how to authenticate with the 8x8 API: its host and its OAuth 2.0 client-credentials flow. It lists no endpoints. 8x8 publishes no OpenAPI specification; every value here comes from the vendor's own documentation, cited per value in x-sources. Checked 2026-11-02: the token endpoint refuses a request with made-up client credentials (HTTP 401)."
