# Update Account

PATCH https://api.coperniq.io/v1/accounts/{account_id}
Content-Type: application/json

Update an existing account. Supports partial updates.

Updatable fields:
- Standard fields (title, description, address, accountType, isActive)
- Contact information (primaryEmail, primaryPhone)
- `contacts`: Contact IDs only (no name, email, phone, etc.). The contacts must be created first via POST /contacts.
- Custom fields (through custom object)

Note: Updates are atomic - either all fields update or none do.

**Note:** The `/clients` path is an alias for `/accounts` and will continue to work until users are individually notified and migrated.
