Payment Service Providers (PSPs) live and die by their ability to offer merchants fast, reliable, and flexible payment options. But the global payments landscape is highly fragmented. Cards, alternative payment methods (APMs), and crypto each require different integrations, settlement processes, and compliance frameworks.
The result? Operational complexity, higher costs, and slower merchant onboarding.
This case study shows why leading PSPs trust TransFi’s unified payments API to deliver multi-rail payment processing across cards, wallets, and crypto—helping them scale faster, serve merchants better, and expand globally.
The Challenge: Fragmented Payment Rails for PSPs
PSPs face daily hurdles when managing global payment acceptance:
- Multiple integrations → each rail (cards, APMs, crypto) adds engineering and compliance overhead.
- Cross-border friction → traditional infrastructure struggles with instant settlement and FX costs.
- Merchant churn → limited support for preferred local methods causes merchants to lose customers.
- Slow scaling → expanding into new geographies requires time-consuming, piecemeal integrations.
For PSPs, this creates an urgent need for a single API for global payments that covers every major rail.
The Solution: TransFi Unified Payments API
TransFi provides PSPs with multi-rail payments infrastructure that integrates cards, APMs, and crypto in one API. Instead of juggling multiple vendors, PSPs get a seamless checkout framework that scales with their merchants.
Key features for PSPs:
- Card payments → support for Visa, Mastercard, and local card networks.
- Alternative Payment Methods (APMs) → wallets, instant bank transfers, QR payments in 100+ countries.
- Crypto payments for PSPs → enable stablecoin acceptance (USDC, USDT) alongside fiat rails
- Unified payments API → one integration, all rails.
- Cross-border payments infrastructure → optimized FX, instant settlement, and compliance-ready rails.
Multi-Rail Payments in Action
A global PSP serving merchants in Europe, LATAM, and Asia struggled with three separate integrations for cards, local APMs, and crypto gateways. This created longer onboarding times and high maintenance costs.
By adopting TransFi’s unified payments API, the PSP achieved:
- Accepting Cards, APMs, and Crypto in a Single API
Merchants gained access to 250+ local methods and stablecoins alongside traditional rails. - Reduced Complexity With Unified Payment Rails
Engineering teams replaced three separate integrations with one, cutting development overhead by 60%. - Cross-Border Efficiency
TransFi’s infrastructure improved settlement speeds and reduced FX costs across 100+ geographies. - Stronger Merchant Retention
By offering a seamless multi-rail checkout, the PSP increased merchant satisfaction and reduced churn.
