favi webhooks
favi webhooks are not part of this product. There is no webhook signing secret, no event catalog, and no callback URL to register. Polling is also unnecessary: search once, then POST /api/export once.
What to use instead
Call the favi HTTP API. See favi developer resources at /docs, the OpenAPI spec at /openapi.json, and the agent skill at /skills/favi/SKILL.md.
