# Hierarchy

A key is bound to one node in your account hierarchy; **read** endpoints cover that node and its subtree, and **write** endpoints (`POST /guests`, `POST /reviews`, `POST /survey-responses`) write to one property within it. The webhook-management endpoints (`/webhooks*`) are the exception — they operate account-wide and ignore the key's node binding (see **Webhooks**) — and so are the attribute definitions of `GET /property-attributes`, which describe the account rather than a property (see **Property attributes**).
