Mux Webhooks
Mux Webhooks deliver signed HTTP callbacks for asset, upload, live stream, and robots job lifecycle events (video.asset.created, video.asset.ready, video.live_stream.active, video.upload.asset_created, robots.job.completed, and many more). Each delivery carries a Mux-Signature header (HMAC-SHA256 over the raw body and a per-endpoint secret) and includes attempt history visible in the dashboard.
