Get the latest saved billing address for a user (with its city -> state -> country chain). If that user's company pays via partner or brand (who_will_pay), the billing address of the paying company's owner user comes back instead, so the invoice always resolves to the party that actually pays. Read-only; returns null in data when no address is stored yet.

Auth

• Bearer account / partner token. user_id must sit inside your own account tree, so it must be a user inside the caller's own company hierarchy.

Rate limit

• No rate limit.

Query

Behaviour

• 200 — { data: {.} } with the address, or { data: null } when none exists. Column aliases,. Also returns city.state.country.
• 422 — user_id missing/invalid or outside the caller's hierarchy.
