Monimo Data API: Membership, Affiliate Status & Walk Records

Samsung Card Co., Ltd. · Banking

Monimo (모니모) is Samsung Card Co., Ltd.'s Android financial super-app for South Korea, bringing Samsung Life Insurance, Samsung Fire & Marine, Samsung Card and Samsung Securities into one signed-in membership. Users can access card products, insurance policies, brokerage holdings and a savings account, sign in with a PIN, FIDO fingerprint or face authentication, or a WCMS certificate, and use Monimo Pay for app-card, QR and over-the-counter payments. Its payment options include Kakao, Toss, Naver, L.Pay, SSG, Coupay, Baemin, SmilePay and Payco; traffic/Cashbee cards, Visa DPE, junior accounts, walk-challenge rewards and NHIS-backed card-limit qualification also sit within the app. It serves domestic financial-group customers in Korea alongside alternatives such as Shinhan SOL, KB Star Banking, Hana 하나Pay and Hyundai Card.

Samsung affiliate contract flags tie Life, Fire, Card and Securities relationships together through slfCntrCstYn, ssfCntrCstYn, hppCntrCstYn and sssCntrCstYn. The customer-management key mnmCstMngtNo anchors profile and membership-state records, while mnmAflcmpC, aflcmpCntrCstYn and aflcmpChnlCstYn describe an individual affiliate relationship. Contact-update data includes separate home and office postal fields, homZip and offiZip; NHIS qualification submissions include the issue number isNo, name fnm and encrypted resident-number field rrnoe.

Walk-challenge submissions add the measurement date wakctMesureBsdt, total steps criDTotWakct, distance criDTotWakDstn, calorie and hourly counts such as h08Wakct, with wakctSyncrnDtm recording the synchronization time. Credit-risk teams can use the affiliate flags to map existing group relationships rather than quantify financial exposure, originations teams can associate qualification and contact records for card-limit assessment, and loyalty operations can reconcile daily activity for walk rewards. These are permissioned integration use cases, not public customer records; openData Studio turns the data model into callable open data, with illustrative routes and mock examples shown below.

Where teams use this data

Samsung Financial group-exposure screen
A credit-risk desk joins slfCntrCstYn, ssfCntrCstYn, hppCntrCstYn and sssCntrCstYn on the same mnmCstMngtNo to see whether one Korean customer is already on Life, Fire, Card and Securities books before extending limit.
NHIS-backed card-limit underwriting
An originations workflow consumes isNo, fnm and rrnoe from the NHIS qualification scrape and matches them to the member address block (homZip, offiZip) when Samsung Card re-underwrites limit.
Walk-challenge reward ops
A loyalty ops job sums criDTotWakct and hourly h08Wakct–h18Wakct per wakctMesureBsdt to settle daily walk rewards without scraping the health home screen.
Affiliate membership sync
An identity platform watches mnmAflcmpC plus aflcmpCntrCstYn / aflcmpChnlCstYn updates, then calls Life check, Fire IPMN0004 and Securities r100 so channel-customer flags stay aligned across the four affiliates.

Frequently asked questions

Which Samsung affiliate membership fields does the Monimo Data API describe?

The contract-customer flags slfCntrCstYn, ssfCntrCstYn, hppCntrCstYn and sssCntrCstYn correspond to Samsung Life Insurance, Samsung Fire & Marine, Samsung Card and Samsung Securities. The member key is mnmCstMngtNo. Affiliate updates use mnmAflcmpC with aflcmpCntrCstYn and aflcmpChnlCstYn for contract-customer and channel-customer status. These flags describe relationships, not financial exposure amounts.

What NHIS qualification data is documented for card-limit assessment?

The qualification submission includes isNo for the issue number, fnm for the member name, rrnoe for the encrypted resident number, plus rspC and svo. The illustrated response includes rspC and isNo. This is qualification data used for Samsung Card limit assessment, not a returned credit-limit amount. Handling actual identity information requires appropriate permission.

Which daily and hourly walk-challenge fields are included?

The sync submission includes wakctSyncrnDtm, wakInYn and criDTotWakct, with dated entries in bsdtWakctList. Each entry can carry wakctMesureBsdt, criDTotWakct, criDTotWakDstn, calorie and hourly counts such as h08Wakct, h12Wakct and h18Wakct. The example illustrates activity uploads for reward reconciliation, not a reward-payment history.

Are these public Samsung production endpoints, and what authentication is described?

No. The routes are illustrative and the example values are mocks, not public production service addresses or customer records. The documented sign-in options are PIN, FIDO fingerprint or face authentication, and a WCMS certificate; sign-in fields include mnmCtfSn and mnmLgnCtfTpDvC. Session renewal supplies accessToken, and subsequent member, affiliate and walk calls require a login session plus Bearer authentication. Actual customer information also requires appropriate permission.
