[null,null,["최종 업데이트: 2025-07-25(UTC)"],[],["A three-way account link involves using the `accounts.link` API. First, a request is made from the MCA account (e.g., 111111111) to link a subaccount (e.g., 2222222) to a new onboarding account (e.g., 3333333), with the `action` set to \"**request**\". Then, using the subaccount's token, another API request is made to approve the link, setting `action` to \"**approve**\". This specifies the `linkedAccountId`, along with services and external identifier.\n"]]
