API Integration & Open Banking Engineering in Sri Lanka
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 Sri Lanka, that means building to the technical expectations of Global: Firms operating in Sri Lanka must align their digital infrastructure with national data protection and financial security standards.

Localised for your market
API Integration Services in Sri Lanka: local requirements we build for
Currency, tax, payments, data protection and 24/7 support — planned into the project from the first sprint.
Currency & pricing
Prices, invoices and reports in Sri Lankan rupee (LKR), with the transaction currency and FX rate stored on every record for cross-border sales.
Tax (VAT / GST)
Sri Lanka applies VAT 18%. We build tax-correct pricing, invoice fields and exportable tax reports; your accountant confirms treatment for your products.
Payments
Customers in Sri Lanka expect LankaQR, Cards and Mobile wallets (eZ Cash, mCash) — integrated with automatic reconciliation.
Data protection
Personal data is governed by the Personal Data Protection Act No. 9 of 2022. We build consent, encryption, access logs and in-region hosting where required.
24/7 availability
Sri Lanka is on UTC+5:30 (same time as India (IST)). Our team works 24/7, so your full business day and any out-of-hours incident are covered.
Delivery timeline
Discovery starts within 5 business days of a signed proposal. Most API integration services engagements ship a first production release in 6–14 weeks, with demos every two weeks.
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. Teams in Sri Lanka (UTC+5:30) feel this most when support is only available in another time zone.
Inconsistent API governance
Multiple teams shipping APIs without standards creates versioning chaos and security gaps. Any customer data involved is also covered by the Personal Data Protection Act No. 9 of 2022.
Legacy core system bottlenecks
Monolithic cores can't expose modern, well-documented APIs without a middleware layer. Teams in Sri Lanka (UTC+5:30) feel this most when support is only available in another time zone.
Open banking compliance pressure
PSD2/open banking-style mandates require secure, standards-compliant APIs with strong consent and auth flows. In Sri Lanka this also means working to Central Bank of Sri Lanka and the Personal Data Protection Act No. 9 of 2022.
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. Sri Lanka runs on UTC+5:30, so peak load and maintenance windows differ from India's.
Breaking changes disrupting live partner integrations
APIs shipped without a versioning strategy force partners into painful, uncoordinated migrations every time the underlying system changes. Sri Lanka runs on UTC+5:30, so peak load and maintenance windows differ from India's.
Our Approach
What our api integration services work covers in Sri Lanka
API strategy & governance
API design standards, versioning policy, and lifecycle governance so every team ships consistent, secure APIs. Personal data handling follows the Personal Data Protection Act No. 9 of 2022.
Open banking API development
Account information and payment initiation APIs built to open banking standards with OAuth2/OIDC consent flows. For Sri Lanka that includes LankaQR, Cards and Mobile wallets (eZ Cash, mCash).
API gateway & management platforms
Implementation and consulting across MuleSoft, Apigee, WSO2, and Kong for traffic management, throttling, and analytics. Our 24/7 team schedules this work around Sri Lanka (UTC+5:30) business hours.
Middleware modernization
Wrapping legacy cores with modern, well-documented REST/GraphQL APIs without a risky core rewrite. Our 24/7 team schedules this work around Sri Lanka (UTC+5:30) business hours.
Developer portal & partner onboarding
Self-service developer portals with sandbox environments that cut partner integration time from weeks to days. Our 24/7 team schedules this work around Sri Lanka (UTC+5:30) business hours.
API security engineering
OAuth2/OIDC, mutual TLS, rate limiting, and API-specific threat protection against abuse and data exfiltration. Personal data handling follows the Personal Data Protection Act No. 9 of 2022.
Versioning and deprecation strategy
A formal API lifecycle policy that gives partners predictable migration windows instead of surprise breaking changes. Releases for Sri Lanka are timed to UTC+5:30 business hours.

Sri Lanka project brief
How an api integration services project for Sri Lanka would run
Sri Lanka has about 21 million people and uses the Sri Lankan rupee (LKR); same time as India (IST). Our team works 24/7 from India, so stand-ups and demos can be scheduled in Sri Lanka business hours rather than ours.
For platform and data work the local constraint is residency and uptime: the Personal Data Protection Act No. 9 of 2022 shapes where data may live, so we plan hosting regions, backups and failover around it and run change windows that suit Sri Lanka time (UTC+5:30).
Business value
What API Integration & Open Banking Engineering in Sri Lanka does for your business
Benefits for your company
- Systems that talk to each other. Banking, ERP, CRM and partner systems exchange data through governed APIs instead of manual exports and spreadsheets.
- Faster partner onboarding. A developer portal, sandbox and clear documentation cut partner integration time from weeks to days.
- Compliance with open-banking rules. Consent flows, security standards and logging that regulators and bank partners expect.
How it can earn or save money
- API monetisation. Usage-based or tiered API plans turn internal data and capabilities into a paid product.
- Partner-driven revenue. Easier integration brings in more partners, resellers and embedded-finance customers.
- Operational savings. Removing manual data handling frees staff time and reduces costly errors.
Illustrative revenue and saving lines, not guaranteed results: outcomes depend on your market, licences and execution.

Our Approach
Our approach to development methodologies
Our approach to custom software engineering draws on a range of methodologies, each selected to match the needs of your API integration services project and your team in Sri Lanka.
Agile Scrum
Best for: Evolving products
Two-week sprints with a working demo at the end of each, so API integration services priorities can change as you learn from users.
Kanban
Best for: Continuous delivery & support
A visual flow of small tasks with work-in-progress limits — ideal for maintenance, integrations and post-launch improvements.
Fixed-scope (Waterfall-style)
Best for: Well-specified builds
Requirements signed off up front with a fixed timeline and price — best when scope is clear and change is unlikely.
Lean MVP
Best for: New ventures
Build the smallest API integration services release that proves demand, measure it with real users, then invest where the data points.
DevOps & CI/CD
Best for: Every project
Automated tests, infrastructure-as-code and push-button deployments so releases are frequent, reversible and boring.
Security-by-design (DevSecOps)
Best for: Regulated & high-value systems
Threat modelling, dependency scanning and code review built into each sprint rather than a pen test at the end.
Why we're different
What sets Hurain Technologies apart for Sri Lanka businesses
Plenty of agencies can build API integration services. Here is what sets us apart for clients in Sri Lanka.
Engineering depth, not a reseller
Your API integration services project is designed and built by our own in-house engineers — no hidden subcontracting chain between you and the people writing code.
Built for Sri Lanka, not copied from elsewhere
Payments, tax, language and data-protection requirements for Sri Lanka are part of the design from day one instead of retrofitted after launch.
Transparent, senior-led delivery
A named project lead, a shared backlog, fortnightly demos and direct Slack access to the engineers — you always know what is being built and why.
Cost advantage without cutting corners
Delivering from India gives clients in Sri Lanka senior engineering at a fraction of typical onshore agency rates, with the same code-review, testing and security standards.
You own everything
Source code lives in your repository from the first commit; IP, infrastructure accounts and documentation transfer to you in full.
We stay after launch
Monitoring, updates and a support SLA mean the team that built your product is the team that keeps it running.
