• SCOPE_REQUIRED — the token lacks read:marketing (reads) or write:marketing (writes).
• ORG_WIDE_TOKEN_REQUIRED — the token is restricted to particular events; this operation reads the whole organization.
• FORBIDDEN — the organization's plan does not include Marketing, or the token's user cannot change goals (writes need an organization admin or the organization settings permission).
