Why Companies Choose IRPR for API Integration
We deliver production-ready integrations on time and on budget.
IRPR has shipped over 200 integrations across 50 countries. Our average delivery time is 12 weeks, and 98% of projects land on schedule. Every integration comes with automated tests, CI/CD, and full documentation.
We specialize in compliance-heavy industries like healthcare and fintech. Our integrations pass HIPAA audits, PCI-DSS certifications, and SOC 2 Type II reports without rework. That saves clients weeks of compliance overhead.
Generic Dev Shop vs IRPR
Not all vendors deliver reliable integrations.
Most generic dev shops bill by the hour, assign junior developers, and ignore compliance. Their integrations break when APIs update and leave you with no documentation.
IRPR takes a different approach. We assign senior engineers, fix the price upfront, and build for long-term maintainability. Every integration includes monitoring, alerting, and a 12-month warranty.

- Junior developers learning on your dime
- No compliance expertise
- Code that breaks on API updates

- No post-launch support
- Fixed price per project
- Senior engineers with 12+ years experience
- HIPAA/PCI/SOC 2 compliance built in

Our API Integration Process
From discovery to deployment, we follow a proven 4-phase approach.
Every project starts with a 2-week Roadmap phase where we define scope, architecture, and a fixed price. No guesswork, no hidden fees.
We then move to development, testing, and deployment with continuous client feedback. After launch, we monitor uptime and provide 12 months of support.
