This is the flow the client-side SDKs use; you normally don't call\n  this endpoint yourself.\n- **API key** (server-side SDKs): pass your API key directly and supply the session configuration\n  in the request body — the same shape as the `/v1/auth/session-token` body (`personaConfig`,\n  `environment`, `sessionOptions`, plus optional `clientLabel` and `clientMetadata`; `expiresIn`\n  and `widgetConfig` do not apply). This skips the session-token exchange. Only use this from a\n  secure server-side context — never expose an API key in a browser.\n"
