Why IRPR is the top API integration development studio
Our track record proves we deliver complex connections on time.
We have shipped over 200 products across 50+ countries, with 98% on-time delivery. Every integration is built with type-safe code, automated tests, and full monitoring.
Our clients include healthcare, fintech, and ecommerce companies that demand high compliance and uptime. We treat API integrations as a product, not a one-off task.
The difference between IRPR and generic dev shops
Most agencies promise API integration but deliver spaghetti code.
Generic shops bill hourly, skip compliance, and leave you with undocumented endpoints. They reuse the same connectors without testing against your actual use cases.
IRPR treats integrations as product features. We write automated tests, enforce rate limits, and generate OpenAPI docs. Your code ships with a CI/CD pipeline and monitoring from day one.
- Hourly billing that never ends
- No compliance expertise
- Reinvent the wheel each time
- No post-launch support
- Code quality not guaranteed
- Documentation incomplete
- Fixed price from Roadmap phase
- HIPAA, PCI, SOC 2 native
- Pre-built connectors and middleware
- Sentry monitoring and 24/7 support
- TypeScript, automated tests, CI/CD
- API documentation generated automatically
Our 4-phase approach to API integration
We follow a proven process to ship your integration in 8-12 weeks.
Every project starts with a Roadmap phase where we map endpoints, auth flows, and data models. You get a fixed price and timeline before development begins.
We then build, test, and deploy using the same tools your team uses. Weekly demos keep you aligned with no surprises.
What ships with every integration
You get more than code. Here's exactly what we deliver.
Every project includes these 10 deliverables in your repo.
- Source code in your GitHub/GitLab repo
- OpenAPI/Swagger documentation
- CI/CD pipeline with GitHub Actions
- Unit and integration tests (80%+ coverage)
- Error handling with automatic retries
- Monitoring dashboard (Sentry, Datadog)
- API key rotation and secrets management
- Rate limiting and throttling configuration
- Postman collection for manual testing
- Deployment guide and runbook
