Do you build wallet infrastructure for Lithuania-registered crypto platforms?

Yes, we build custody and wallet infrastructure aligned to the AML/CTF controls Lithuania's crypto-asset registration framework expects.

Do you work with MuleSoft, Apigee, and WSO2?

Yes, we design, implement, and optimize API management on MuleSoft Anypoint, Apigee, WSO2, and Kong.

Can you build open banking APIs for our institution?

Yes, including account information and payment initiation APIs with compliant consent and authentication flows.

How do you speed up partner API onboarding?

Through self-service developer portals with sandbox environments, clear documentation, and standardized authentication.

Can you modernize our legacy core without a full rewrite?

Yes, we wrap legacy cores with a modern API middleware layer, avoiding the risk and cost of a full core replacement.

API Integration & Open Banking Engineering in Lithuania

Banks, fintechs, and platform businesses run on APIs — and every unreliable integration becomes a partner escalation. Hurain Technologies designs, builds, and secures API ecosystems, from open banking connectivity to enterprise API management, so your partner integrations are fast to onboard, well-governed, and secure by default. In Lithuania, that means building to the technical expectations of Europe: Payment institutions and e-money issuers are licensed and supervised by the Bank of Lithuania, known for comparatively fast licensing timelines among EU regulators.

Lithuania Regulatory Landscape

What api integration services buyers in Lithuania need to know

Payment institutions and e-money issuers are licensed and supervised by the Bank of Lithuania, known for comparatively fast licensing timelines among EU regulators.
Open banking API integrations commonly reference PSD2-derived technical standards for account access and payment initiation.
Crypto-asset service providers registered in Lithuania have operated under national AML registration requirements that are tightening ahead of full MiCA implementation.
We build the technical infrastructure these processes expect, alongside Lithuania-qualified legal and compliance counsel for the licensing application itself.

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.

Our Approach

How we deliver api integration services in Lithuania

API strategy & governance

API design standards, versioning policy, and lifecycle governance so every team ships consistent, secure APIs.

Open banking API development

Account information and payment initiation APIs built to open banking standards with OAuth2/OIDC consent flows.

API gateway & management platforms

Implementation and consulting across MuleSoft, Apigee, WSO2, and Kong for traffic management, throttling, and analytics.

Middleware modernization

Wrapping legacy cores with modern, well-documented REST/GraphQL APIs without a risky core rewrite.

Developer portal & partner onboarding

Self-service developer portals with sandbox environments that cut partner integration time from weeks to days.

API security engineering

OAuth2/OIDC, mutual TLS, rate limiting, and API-specific threat protection against abuse and data exfiltration.

Versioning and deprecation strategy

A formal API lifecycle policy that gives partners predictable migration windows instead of surprise breaking changes.
