This does not trigger another website request. Download and file identifiers must come from that adapter; arbitrary browser filesystem paths are not accepted. Requires edit access to the session and control of its active browser. Access is checked again during transfer. A 404 may mean the browser has ended or the download is not yet ready; repeating GET is safe. Files are temporary and disappear when removed or when the browser ends. ## OpenAPI ````yaml /openapi.json get /sessions/{sessionId}/browsers/{browserId}/downloads/{downloadId}/files/{fileId} openapi: 3.0.3 info: title: Effective API version: 2.0.0 description: The public Effective REST API.
