The challenge

Card-only checkouts leave money on the table.

Shoppers in Germany want Sofort. In Brazil — PIX. In Poland — BLIK. In the Netherlands — iDEAL. In Southeast Asia — GrabPay and Atome. Card-only checkouts lose 20–40% of conversions in these markets.

Integrating each payment method means a new PSP contract, new compliance paperwork, new edge cases to support. Paynexus pre-packages 40+ local methods so you launch a new country without a new project.

Business outcomes

What you'll see in production.

+15–25%

Conversion in new markets

Shoppers convert at dramatically higher rates when they see a familiar local payment method instead of being forced to type a card.

40+

Local methods ready

PIX, iDEAL, Sofort, BLIK, MB WAY, Alipay, GrabPay, Boleto, Konbini — one integration, every market.

<1%

3DS friction rate

Frictionless 3DS triggers a challenge only when risk score requires it. Most customers never see a step-up screen.

Local

Settlement, no FX markup

Settle in each market's local currency, avoid 2–4% cross-border FX fees, and keep pricing psychology clean.

Capabilities

Everything global checkout needs.

40+ local payment methods

Bank transfers, wallets, vouchers, real-time payments, cash-at-counter — one API, consistent response shape. Query GET /api/v1/payways by country and currency to get the right list.

BNPL partners

Klarna, Afterpay, Atome, and regional installment plans wired in. Let shoppers split a $200 purchase into four $50 installments without you taking the credit risk.

3DS orchestration

Frictionless 3DS 2.x whenever the issuer allows it. Step-up challenge only on high-risk transactions. Full exemption logic handled: TRA, low-value, whitelisted merchant.

Dynamic Currency Conversion

Show an international card-holder their price in their home currency at checkout. DCC uplift flows back to you. Fully opt-in per transaction.

Settlement currency choice

Accept in BRL, settle in USD. Or accept in USD, settle in EUR. Per-merchant, per-PSP settlement rules keep your finance team happy.

PSD2 / SCA compliance

Every European transaction complies with PSD2 Strong Customer Authentication. Exemption flags and liability shift handled transparently.

How to integrate

A global checkout in four steps.

Query available payways per region

Call GET /api/v1/payways?country=BR&currency=BRL to get the right methods for each shopper. The list updates automatically as we add new methods.

Render local methods at checkout

Show shoppers what's familiar — PIX in Brazil, iDEAL in the Netherlands, BLIK in Poland. Your UI logic stays simple; the compliance is ours.

Let Paynexus orchestrate 3DS

Call POST /api/v1/deposits with the chosen payway. We decide whether to attempt frictionless 3DS, trigger a challenge, or skip it entirely.

Settle in your chosen currency

Receive funds in USD, EUR, or whatever currency your finance team operates in. FX is handled with pre-negotiated rates — no surprises on the monthly statement.
