API Integration & Open Banking Engineering in São Paulo

Q: Do you support Pix integration for Brazilian payment platforms?

Yes, we integrate Pix alongside card and wallet payment methods within a unified orchestration and reconciliation layer.

Banks, fintechs, and platform businesses run on APIs — and every unreliable integration becomes a partner escalation.

In São Paulo, that means building to the technical expectations of the local market.

São Paulo Market Landscape

Why api integration services is critical in São Paulo

São Paulo hosts the B3 stock exchange and the largest concentration of fintech unicorns and scale-ups in Latin America.

São Paulo-based crypto businesses now operate under Brazil's 2023 crypto-asset law, giving the BCB direct oversight of virtual asset service providers.

The Challenge

Problems we see teams struggling with

Slow partner and third-party onboarding

Without a proper API gateway and developer portal, every new integration takes weeks of custom engineering.

Inconsistent API governance

Multiple teams shipping APIs without standards creates versioning chaos and security gaps.

Legacy core system bottlenecks

Monolithic cores can't expose modern, well-documented APIs without a middleware layer.

Open banking compliance pressure

PSD2/open banking-style mandates require secure, standards-compliant APIs with strong consent and auth flows.

No visibility into API usage and abuse patterns

Without centralized gateway analytics, teams often don't know which partners are hitting rate limits, which endpoints are being scraped, or where latency is actually coming from.

Breaking changes disrupting live partner integrations

APIs shipped without a versioning strategy force partners into painful, uncoordinated migrations every time the underlying system changes.
