# Update account settings

> Allow-listed partial update; unknown keys are dropped. Text fields are trimmed (max 255) and `null`/"" clears them.
Sending `vatNumber` triggers a VIES lookup that sets `vatValid` server-side. A US, CA or AU country requires `region`.
Writes an UPDATE_USER_SETTINGS audit entry listing the changed field names. Session only — API tokens are rejected
(Uncertain: an in-code comment says API tokens can reach it, but the route uses verifyAuth, which refuses them).
