API integration development agency track record
IRPR has shipped over 200 integrations for clients in 50+ countries.
Our team of senior engineers has built integrations for healthcare, fintech, ecommerce, and logistics companies. We focus on reliability, security, and speed. Every integration is documented, tested, and deployed with CI/CD.
We maintain a 98% on-time delivery rate and a 99.9% uptime SLA for all integrations we deploy. Our clients stay with us because we deliver clean, maintainable code that works from day one.
Why choose IRPR for API integration development
Most dev shops overpromise and underdeliver. We don't.
Generic dev shops often start with a low estimate and then add scope creep, change orders, and surprise fees. They write undocumented code that breaks when you upgrade a third-party API. And they rarely understand compliance requirements like HIPAA or PCI-DSS.
IRPR gives you a fixed price from day one. We build with clean code, full documentation, and automated tests. Every integration is designed to scale and easy to maintain. We also handle compliance so you don't have to.
- No fixed pricing - estimates change
- Scope creep and surprise invoices
- Undocumented, unmaintainable code
- No compliance expertise
- Slow email-only communication
- No post-launch support
- Fixed price quoted in week 2
- Clear roadmap with no hidden fees
- Documented APIs and clean code
- HIPAA, PCI-DSS, SOC 2 compliance
- Daily standups and Slack access
- 30 days post-launch support included
Our API integration process
We follow a four-phase process that eliminates surprises.
Phase 1: Discovery and Audit. We map your current tools, data flows, and pain points. We identify every API, endpoint, and authentication method involved. This phase takes 1-2 weeks and produces a detailed integration specification.
Phase 2: Architecture and Roadmap. We design the integration architecture, choose the right middleware (Kafka, MuleSoft, or custom), and create a fixed-price roadmap. You approve the plan before any code is written.
What ships with every API integration
Every integration comes with a complete delivery package, not just code.
We believe in full transparency. You get everything you need to run, maintain, and extend the integration yourself. No vendor lock-in, no black boxes.
Our delivery includes source code, documentation, monitoring, and a compliance report. You can hand it to your internal team or ask us to continue supporting it.
- Source code in your private GitHub repo
- API documentation with Swagger/OpenAPI
- CI/CD pipeline on GitHub Actions or GitLab CI
- Error monitoring with Sentry
- Performance dashboards with Datadog
- Load testing results with k6
- Compliance audit report (HIPAA, PCI-DSS, SOC 2)
- Post-launch support for 30 days
- Unit and integration test suite
- Deployment runbook and architecture diagram

Full code ownership
You own the source code, documentation, and all deliverables. No licenses, no royalties, no ongoing fees. We hand over the GitHub repo and CI/CD pipeline at project completion.
Senior engineers only
