InfinitePay data API: NSU captures, Pix and wallets

CloudWalk · Payments 4.9 ★

InfinitePay Tap, Conta, Cartão is CloudWalk's Brazilian merchant app (on-device InfinitePay) that turns an Android 10+ NFC phone into a free InfiniteTap card reader and pairs it with a PF/PJ digital account, Pix at zero fee, payment links, billing, POS inventory and a no-annual-fee smart card. Shopkeepers, MEI, CNPJ firms and delivery riders accept debit, credit and wallets by tap — sales over R$200 ask for the customer's PIN — then choose to receive in the moment or in one business day, with rates that already bundle prepayment. Team Mode installs a sales-only client on as many phones as the shop needs; the same login generates installment links up to 12× for WhatsApp and DMs, issues Pix or card cobranças, runs an online catalog, compares MDR in-app, and can open an instant loan paid from sales. The smart card pays 1.5% cashback and sits in the phone wallets. Published for Brazil only (CloudWalk Payment Institution CNPJ 18.189.547/0001-42, Rua Eugênio de Medeiros 303, São Paulo), it holds a 4.87 rating across 1.04 million Google Play reviews, 10 million-plus installs and a #7 free-finance slot, sitting next to Stone, PagBank, Cielo, Mercado Pago Point, SumUp and Ton for the same SoftPOS-plus-conta slot.

CNPJ document_number lands on the same signed-in merchant session as wallets, cardholder and products_allowed, with identity_validation status and account_kind (MerchantPj versus a CPF seller) deciding which till is a company. SoftPOS and delivery taps then key each card capture by nsu; Pix outflows are tracked beside current_tpv, while active_loan and card credit_statement rows reuse the same handle.

ERP and courier stacks reconcile those receipts against receivables reference_id and BACEN validation state so a shop that takes NFC on Android 10, Pix at zero fee and a no-annual-fee card can close the day without a separate acquirer file. openData Studio turns that merchant session into callable open data.

Where teams use this data

SoftPOS and delivery NSU reconciliation
A shop or dark-kitchen ERP pulls each InfiniteTap capture by nsu, matches amount and current_tpv to the courier's phone, and flags Team Mode tills that settled off-shift.
Pix cash-out versus wallet headroom
Treasury bots read wallets on the merchant session, send Pix cash-outs to suppliers, and stop the drain when identity_validation is still pending.
Receivables and MDR close
Finance stacks walk receivables by reference_id against the daily sales listing so 1-business-day prepayment and installment plans land in the same ledger as the till.
Sales-backed lending watch
A credit desk reads active_loan next to current_tpv and account_kind so a CNPJ merchant's instant loan is sized off captured volume, not a bureau file alone.

Frequently asked questions

What merchant fields does the signed-in session return?

GET /v1/merchants/me/profile returns wallets, cardholder, merchant.document_number, products_allowed, legal_representative, identity_validation, handle, is_company, phone_number and avatar_url once the sign-in JWT is attached.

How are InfiniteTap card sales identified?

Each capture is stored under nsu. GET /v1/sales/daily lists them for the day together with current_tpv; GET /v1/receipts/{nsu} returns the receipt the till, Team Mode phone or delivery rider just took, and receivables are keyed separately by reference_id.

Does the surface cover Pix and the digital account?

Yes. Wallets on the merchant profile hold the PF/PJ conta; POST /v1/transfers/pix sends Pix out; current_tpv is the captured volume the instant loan and cash-out limits sit against. Pix in on the till is the zero-fee sales rail advertised next to NFC.

How does InfinitePay authenticate merchants?

A password check at POST /v1/merchants/sign-in, or a QR sign-in from an already paired phone. The issued jwt_token is sent as a Bearer Authorization header on later first-party calls; GET /v1/merchants/me/devices lists live devices.
