Webhook Ecosystem & Event Architecture — Outbound events — invoice finalized, payment failed, subscription changed — pushed reliably to customer and internal systems with retries and signatures. Webhooks are the nervous system that lets dunning tools, CRMs, and custom workflows react to billing state without polling.
Webhook Ecosystem & Event Architecture lives in the Platform & Intelligence phase of Grow Revenue — the stage where you retain, expand, and compound revenue on the platform. In the corpus tool index this phase maps to the Analytics and Data platform and Cost & FinOpscategories.
