# LangChain Webhooks and Event Dispatch (Python)
## Overview
A team wires per-tool webhook dispatch from their LangChain agent via FastAPI
`BackgroundTasks` — analytics is always N seconds late because `BackgroundTasks`
fire **after** the HTTP response closes, not during the stream (P60). Worse:
the `BaseCallbackHandler` they attached via `.with_config(callbacks=[h])`
fires on the outer agent but is dark on the subagent's tool calls — custom
callbacks are **not** inherited by LangGraph subgraphs (P28), they must be
passed via `config["callbacks"]` at invoke time.
Pain-catalog anchors handled here:
- P28 — Callbacks via `with_config` don't propagate to subgraphs
