Premium API Integration Development DevelopersAPI Integration
We build secure, scalable API integrations that connect your systems in 12 weeks. Fixed price, full ownership, and senior engineers only.
IRPR builds premium API integrations that connect your SaaS tools, legacy systems, and third-party services. We use REST, GraphQL, Webhooks, and OAuth2 to build integrations that are secure, fast, and maintainable.
Every project ships in 12-14 weeks with a fixed price between $80K and $250K. We handle compliance — SOC 2, HIPAA, PCI-DSS, GDPR — and include monitoring, error handling, and documentation by default.
Our clients are CTOs at healthcare startups needing HIPAA-compliant EHR integrations, VPs of engineering at fintech companies requiring PCI-DSS payment gateway connections, product managers at SaaS firms building real-time data sync, and IT directors at logistics companies integrating with carrier APIs.

Why your business needs premium API integration development
API integrations are the backbone of modern software. A single broken integration can cost you customers and compliance.
Consumers expect real-time data syncing between apps. If your CRM doesn't talk to your ERP or your payment gateway fails silently, you lose trust. Premium API integration development ensures every endpoint is designed for failure, retries, and security.
IRPR has built over 200 integrations across 14 industries. Our average project ships in 12 weeks with a 98% on-time rate. We use tools like OpenAPI specs, automated contract testing, and circuit breakers to guarantee reliability.
How we differ from generic API development shops
Most agencies build brittle integrations that break after a third-party API update. IRPR builds for resilience from day one.
We start every premium API integration project with a deep architecture review. Our Roadmap phase (week 2) defines every endpoint, error code, and retry strategy before a single line of code is written.
Your team gets a dedicated senior engineer, automated integration tests, and a CI/CD pipeline that includes contract tests against actual third-party sandboxes. We don't hand off to juniors.
- Hourly billing, no fixed price
- Junior developers with minimal oversight
- No contract testing against APIs
- Code ownership often disputed
- No monitoring or alerting defaults
- Integrations fail silently after API updates
- Fixed price from Roadmap phase
- Senior engineers only (7+ years average)
- Automated contract tests via Postman/Newman
- Full code ownership transferred to you
- Sentry error tracking and PagerDuty alerts
- Circuit breakers and idempotency built in
Our API integration development process
We follow a four-phase process that guarantees clarity, speed, and quality.
Phase 1: Idea. We meet with your stakeholders and map every data flow. We identify endpoint dependencies, auth methods, and compliance requirements.
Phase 2: Roadmap. By the end of week 2, you get a fixed price quote, detailed architecture diagram, and a week-by-week delivery plan. No surprises.
What ships with every premium API integration
You don't just get endpoints. You get a complete production-ready module with monitoring and ownership.
Every integration includes automated deployment scripts, error tracking, and a runbook for common failures. We also provide a Postman collection and integration tests.
Your team can extend the integration immediately because the code is fully owned by you. No licensing, no black boxes.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions
- Automated contract tests (Postman/Newman)
- Sentry error tracking with alerts
- PagerDuty or Slack notification integration
- OpenAPI 3.0 specification document
- Postman collection with all endpoints
- Retry and circuit breaker logic
- Rate-limit handling for third-party APIs
- Deployment runbook and admin credentials
