Connect Tucambista exchange orders, rate feeds, and account data to your stack — safely
Tucambista (Tu Cambista SAC, RUC 20602160557) is a Peruvian online casa de cambio registered with SUNAT and supervised by the Superintendencia de Banca, Seguros y AFP (SBS). The app lets individuals and businesses swap US dollars and Peruvian soles in under 15 minutes, fully online. That activity produces structured, server-side records — exchange operations, locked quotes, deposit vouchers, registered bank accounts, and KYC profiles — that finance, accounting, and treasury teams want to query programmatically. We build the protocol analysis and API layer that exposes it under authorization.
Feature modules
Exchange order API
Create and read FX operations: request a quote for an amount and direction, lock the rate for a short window, register the user's bank deposit, attach the receipt image, and poll the order until PAID. Concrete use: a fintech or accounting SaaS that books each currency conversion as a journal entry the moment Tucambista marks the payout complete.
Rate feed & reference rates
Pull the live commercial buy / sell rate plus the daily tipo de cambio SUNAT and SBS reference values. Concrete use: a treasury dashboard that compares Tucambista's spread against bank rates each morning and flags when the savings versus a bank wire exceed a threshold.
Statement & voucher export
List a user's or company's historical operations with date-range, direction, and status filters; download the deposit voucher and Tucambista transfer constancia. Concrete use: month-end close — export all USD→PEN operations to Excel, match them against the bank statement, and archive PDFs for SUNAT bookkeeping.
Account login & KYC profile
Mirror the app authorization flow (token issuance, refresh, session validation) and read the verified profile: person vs. business, DNI or RUC, contact data, and KYC status. Concrete use: a partner portal that lets a corporate client's finance users sign in once and see their Tucambista activity without re-keying credentials.
Registered bank accounts
Read and manage the destination accounts a user has saved (bank, currency, CCI / account number masked). Concrete use: payout routing — an ERP picks the right soles account automatically when scheduling a recurring conversion, instead of a treasurer choosing it by hand.
Promotions, referrals & webhooks
Surface active coupons (the app ran coupon campaigns such as CONTODO2025 in early 2025) and referral credit, and subscribe to order.created, deposit.received, order.paid events. Concrete use: a loyalty engine that grants points the instant a referred user completes their first exchange.
Data available for integration (OpenData perspective)
The table below maps the Tucambista data we can typically expose through an authorized API layer, the screen or feature it originates from, its granularity, and a typical downstream use. All access is performed under customer authorization or via documented/authorized endpoints.
| Data type | Source (screen / feature) | Granularity | Typical use |
|---|---|---|---|
| Exchange operations | "My operations" / order detail | Per operation: id, direction, gross amount, net amount, applied rate, fee, status, timestamps | Reconciliation, accounting journal entries, treasury reporting |
| Quotes / rate locks | New exchange → "Cotizar" | Per quote: requested amount, locked buy/sell rate, validity window | Pricing models, slippage analysis, audit of executed vs. quoted rate |
| Commercial & reference rates | Home "Dólar hoy" widget | Intraday buy/sell; daily SUNAT and SBS reference | FX dashboards, hedging signals, compliance referencing |
| Registered bank accounts | "Mis cuentas bancarias" | Per account: bank, currency, masked account / CCI, holder name | Payout routing, KYC verification, anti-fraud checks |
| Deposit vouchers / constancias | Order step "Subir voucher" / transfer receipt | Per operation: image/PDF, bank, amount, reference number | Document archival, SUNAT bookkeeping, dispute resolution |
| User / company profile (KYC) | Registration & profile | Person vs. business, DNI / RUC, contact, KYC status | Onboarding, risk scoring, segmentation |
| Savings & volume stats | Dashboard "Has ahorrado" | Aggregate per user: total exchanged, total saved vs. bank rate | Customer analytics, retention, loyalty tiers |
| Coupons & referral credit | Promotions / referral screen | Per code: discount, expiry, referral balance | Loyalty engines, campaign attribution |
Typical integration scenarios
1. Corporate treasury reconciliation
Context: a Lima-based importer converts USD to PEN several times a week and must tie each conversion to its bank statement. Data/API: the Exchange order API (GET /operations?from=&to=&direction=USD_PEN) plus voucher export. OpenFinance mapping: the order feed behaves like an OpenBanking "transactions" resource — standardized fields (amount, currency, counterparty, booking date, status) that an aggregator can normalize alongside the company's bank-account transactions.
2. Accounting / ERP auto-posting
Context: an accounting SaaS wants each Tucambista operation to appear as a posted entry with the SUNAT rate of the day. Data/API: order.paid webhook + the reference-rate endpoint. OpenFinance mapping: event-driven push of financial movements — the same pattern as a payment-initiation confirmation callback — lets the ERP post without polling and keeps the SUNAT/SBS rate attached for tax compliance.
3. Multi-house rate comparison dashboard
Context: a personal-finance product shows users the best dollar rate across Peruvian exchange houses. Data/API: the Tucambista rate feed (GET /rates) polled every few minutes. OpenFinance mapping: a read-only "product information" endpoint — analogous to OpenBanking product/price APIs — aggregated with peer rates so the user picks where to exchange.
4. Embedded FX in a B2B portal
Context: a payroll or supplier-payments platform wants to offer "convert and pay in soles" without leaving its UI. Data/API: account login (token exchange), quote → lock → create order, registered-bank-account selection. OpenFinance mapping: a delegated-authorization flow plus payment-initiation-style order creation — the platform acts as an authorized third party on the user's behalf.
5. Compliance & audit archive
Context: a regulated entity must retain proof of each FX operation, the rate applied, and the consent given. Data/API: statement export (JSON + PDF constancias), plus the consent/access log we ship with the integration. OpenFinance mapping: consent records and immutable transaction exports — the audit primitives the SBS Finanzas Abiertas roadmap expects from data recipients.

Technical implementation
Three representative snippets — auth, statement export, and a webhook payload. Field names are illustrative of the integration shape, not a published Tucambista contract.
Compliance & privacy
We integrate only under customer authorization or via documented/authorized endpoints, never by circumventing security controls. For a Peruvian fintech this means aligning with Ley N° 29733 (Ley de Protección de Datos Personales) and its regulation, honoring SBS supervision of online exchange houses, and referencing the official tipo de cambio SUNAT/SBS correctly for tax and accounting use. Looking ahead, the SBS created a Departamento de Finanzas Abiertas (Open Finance) in 2025 and published a four-phase roadmap (BaaS rules expected June 2026; first shared-data groups from late 2027) — our integrations are designed to slot into that consent-and-API model as it rolls out. Background on the framework is summarized by the Superintendencia de Banca, Seguros y AFP del Perú and on Wikipedia's open banking overview.
Practical safeguards we ship: scoped access tokens, consent and access logs, data minimization (only the fields the use case needs), masking of account numbers, encryption in transit and at rest, and configurable retention. NDAs are signed on request, and we document exactly which endpoints are used and on whose authority.
Data flow / architecture
A simple, auditable pipeline:
- Client app / Tucambista session → authorized API connector (token exchange, request signing)
- Ingestion / API layer → normalizes orders, rates, vouchers; emits webhooks
- Storage → encrypted operations store + document/voucher archive + consent log
- Output → your REST API, Excel/PDF exports, BI dashboard, or ERP/accounting connector
Typical modules
- Auth & session refresh
- Order lifecycle (quote → deposit → payout) and webhooks
- Rate feed + SUNAT/SBS reference rates
- Statement, voucher, and constancia export
- Account & KYC profile sync, registered bank accounts
Market positioning & user profile
Tucambista sits in Peru's online casa de cambio segment — a market that grew out of Lima fintech startups and now serves both retail savers and SMEs. Its users are primarily Peru-based: individuals comparing the daily dollar rate against banks, freelancers and remote workers receiving USD, importers/exporters and other businesses (the app cites 9,000+ businesses) that need fast soles settlement, and accountants who reconcile against SUNAT rates. The product is mobile-first (Android via Google Play package com.tucambista_mobile2 and iOS on the App Store) with a complementary web platform at tucambista.pe. Recent activity includes coupon-driven acquisition campaigns through 2024–2025 (e.g. promo codes like CONTODO2025) and continued emphasis on sub-15-minute transfers and SBS supervision as trust signals. For an integrator, that profile means the highest-value endpoints are transaction/statement export for B2B accounting and a rate API for consumer comparison products.

Similar apps & integration landscape
Tucambista is one of several regulated online exchange houses and money apps used in Peru and beyond. Teams building FX, treasury, or accounting tooling often need a unified view across more than one of them, so we list the broader ecosystem here for context (no ranking, no criticism — just the landscape integrators ask about).
- Kambista — one of Peru's first online dollar/sol exchanges; holds the same kind of operation history and registered-account data, so users who also work with Kambista frequently want a single transaction export across both platforms.
- Rextie — a large Peruvian online casa de cambio with no-commission transfers; its order and rate data is a natural second source for a multi-house treasury dashboard.
- Tkambio — an SBS-registered exchange known for fast transfers and a simple UI; relevant when an integrator needs to reconcile FX operations spread across several apps.
- Securex — oriented toward business and higher-volume FX with treasury features; pairs with Tucambista for companies that split flows between providers.
- Cambio Seguro — another online soles/dollars exchange; its statements and vouchers slot into the same accounting-export use case described above.
- Cocos y Lucas — a digital exchange with bank-backed processing; comparable order data, often consolidated with Tucambista activity for month-end close.
- Instakash — a Lima fintech offering fast online currency exchange; relevant to anyone aggregating Peruvian FX rates and operations.
- Wise — a global multi-currency account widely used for cross-border USD/PEN flows; teams comparing mid-market rates against local houses like Tucambista regularly pull both into the same dashboard.
