Why choose an affordable API integration development partner
IRPR delivers reliable API integrations at a fixed price.
We have shipped over 200 products across 50 countries. Our integrations handle millions of API calls per month with 99.9% uptime.
As an affordable API integration development partner, we start projects at $80K and deliver in 8-12 weeks. We use senior engineers only, no junior staff.
The difference between a generic dev shop and IRPR
Not all API integration partners deliver the same quality.
Generic shops often use junior developers and hourly billing. They miss deadlines and produce fragile code.
IRPR uses senior engineers, fixed pricing, and a proven 4-phase process. We deliver clean, documented APIs that scale.
- Hourly billing with no cap
- Junior developers learning on the job
- No compliance documentation
- No post-launch support
- Code that breaks with API changes
- No monitoring or error tracking
- Fixed price from $80K
- Senior engineers with 10+ years experience
- HIPAA, PCI-DSS, SOC 2 compliance built in
- 30 days of support after launch
- Resilient code with retry and fallback logic
- Sentry error tracking and uptime monitoring
How we build your API integration in 4 phases
Our process ensures you get a working integration in weeks, not months.
We start with a 1-week discovery to map your data flows and endpoints. Then we build a prototype in 2 weeks.
After you approve the prototype, we complete the integration with full testing and documentation. The final phase is deployment and monitoring setup.
What ships with your API integration
Every project includes these deliverables by default.
You get source code, documentation, and monitoring tools.
- Source code in your private GitHub repo
- API documentation in Swagger/OpenAPI
- CI/CD pipeline with GitHub Actions
- Unit and integration tests (80%+ coverage)
- Sentry error tracking and performance monitoring
- Deployment scripts for AWS, GCP, or Azure
- Postman collection for manual testing
- 30 days of post-launch support
