Webhook
An **HTTP callback** when an event happens — new row, form submit, payment — triggering your automation.
When to use
Connecting SaaS tools to LLM workflows without polling.
When not
When you need guaranteed ordering without a queue — add idempotency and retries.
Example
Google Sheet row added → POST `/hooks/row` → LLM summarizes → Slack notifies ops.
