Facebook Comment Replies API

Changed on

Pull replies under a Facebook comment — author, text, likes, and time.

The Facebook Comment Replies API lets you pull comments with author, text, likes, and replies for Facebook comment replies with a single REST call. No OAuth, no infrastructure to maintain, and no platform SDKs — send the request, get clean structured JSON back. Pass cache=true to serve from the 24h cache (0 credits on hit); default is always fresh. Selected profile endpoints also accept cacheMaxAge=1d|3d|7d|14d|30d.
