API integration development metrics that matter
Our track record shows predictable results for complex integrations.
IRPR has shipped over 200 integrations across 50 countries. Our average delivery time is 12 weeks from kickoff to production, and 98% of projects finish on time. Each integration is built with automated tests, logging, and monitoring from day one.
Clients see measurable improvements: 40% fewer manual data entry hours, 25% faster order processing, and 99.9% uptime on API endpoints. We use tools like Sentry, Datadog, and PagerDuty to catch issues before they affect users.
The difference between a generic agency and IRPR
Most agencies treat API integration as an afterthought. We treat it as a product.
Generic dev shops often start coding without a clear roadmap. They use hourly billing, change scope without notice, and skip compliance checks. You end up with untested integrations that break when APIs change.
IRPR delivers a fixed-price contract after a 2-week Roadmap phase. We assign a senior lead engineer, run automated integration tests, and give you full code ownership. Every integration is documented with OpenAPI specs and monitored in production.
- Vague timelines and scope creep
- Hourly billing with surprise invoices
- No compliance focus (HIPAA, PCI, SOC 2)
- Junior developers with little oversight
- Manual testing and no monitoring
- Code stays with the agency
- Fixed price after 2-week Roadmap
- Senior engineers only (10+ years experience)
- Compliance-first: HIPAA, PCI, SOC 2, FERPA
- Dedicated lead engineer for your project
- Automated CI/CD, test coverage >90%, Sentry monitoring
- Full source code in your Git repo
How we build your API integration in 4 phases
Our process from idea to production is transparent and iterative.
Each phase has clear deliverables and go/no-go decisions. You see progress every two weeks and can adjust priorities based on real feedback.
We use a standardized framework (Idea -> Roadmap -> Product -> Release) that has been tested on 200+ projects. This guarantees no surprises on budget or timeline.
What ships with every integration project
You get more than just working code. Every project includes a full delivery package.
We believe in handing over production-ready systems, not prototypes. Our documentation and monitoring setup ensure your team can operate the integration independently.
All artifacts are organized in your own GitHub repository with clear readme files and deployment instructions.
- Source code in your Git repo (private, your account)
- CI/CD pipeline on GitHub Actions or GitLab CI
- API documentation (Swagger/OpenAPI 3.0)
- Error monitoring with Sentry
- Logging and dashboards in Datadog or Grafana
- Unit tests with 90%+ coverage
- Integration tests that run on every pull request
- Deployment runbook and rollback procedure
- 30 days of post-launch support
- Architecture diagram and data flow documentation
What we ship in this practice.
Stripe payment integration for a SaaS billing platform

Why teams hire us.
Fixed price, not hourly
Every project gets a fixed quote after the 2-week Roadmap phase. No hourly billing, no surprise invoices, no scope creep charges. You know the total cost before we write a line of code.
Senior engineers only (10+ years)
All engineers have a minimum of 10 years experience. We do not outsource or use junior developers. Every integration is built by someone who has shipped production APIs at scale.
Full code ownership from day one
All source code, documentation, and configuration files are in your GitHub repository. You own everything. No licensing fees or vendor lock-in.
Compliance-first approach
We build HIPAA, PCI-DSS, SOC 2, and FERPA compliance into every integration. Data encryption, audit trails, and access controls are not afterthoughts.
2-week sprint cycles with live demos
You see working software every two weeks. We demo on a staging environment and adjust priorities based on your feedback. No long waits for a final reveal.
Post-launch warranty and support
Every integration comes with 30 days of proactive support. We monitor for errors, handle edge cases, and provide hotfixes if needed. After that, you can extend support monthly.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
