# onboarding.save

Record which setup questions you answered or skipped, whether you finished, and whether you agree to get your tax slips and pay statements by email. It changes nothing else about your profile. Over the API and MCP only answered, skipped and completed are accepted: agreeing to get tax slips by email (eDelivery) is the person's own choice in the portal and is refused with INTERACTIVE_PORTAL_REQUIRED.
