# Update Account Settings

Updates only named account settings and returns the current state. Inaccessible settings, unknown preview tags or malformed blacklists refuse the whole call before writing; credentials cannot be changed here. The result’s refusals lists settings the platform rejected during save, while other changes may have been stored.
