What an experienced API integration development partner delivers
We build integrations that work reliably under load and meet compliance requirements from day one.
Every integration we build includes automated testing with Postman and CI/CD pipelines on GitHub Actions. We use Sentry for error tracking and Datadog for performance monitoring.
Our team has built over 200 integrations connecting platforms like Salesforce, Shopify, and Epic. Each one ships with full documentation and a runbook.
Generic dev shop vs IRPR: the integration difference
Not all partners deliver production-grade, compliant integrations on schedule.
Generic shops often rewrite the same connectors from scratch, miss compliance deadlines, and hand over code without tests. You pay hourly and hope for the best.
IRPR gives you a fixed price, senior engineers with 10+ years experience, and a delivery guarantee. We audit every integration for security and performance before launch.
- Hourly billing with no cost cap
- Junior developers on your project
- No compliance expertise
- Deliverables miss deadlines
- No monitoring or error tracking
- Code ownership unclear
- Fixed price quoted in week 2
- Senior engineers only, 10+ years each
- HIPAA/PCI/SOC 2 built in
- 98% on-time delivery
- Sentry + Datadog out of the box
- Full code ownership after project
Our integration process: from discovery to production
We follow a four-phase approach that removes surprises and keeps timelines predictable.
The entire process takes 8-12 weeks for a typical integration. Each phase ends with a deliverable that you review and approve.
We start with a 1-week discovery sprint to map your systems and define endpoints. Then we move to rapid development, QA, and finally deployment with monitoring.
What ships with every integration project
You don't just get a working integration. You get a full product delivery package.
Every integration includes source code, documentation, and monitoring tools. We don't leave you with black-box code.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions
- Postman collection with all endpoints
- Sentry error tracking with alerts
- Datadog dashboards for latency and errors
- API documentation in OpenAPI/Swagger
- Load test report with 1000+ concurrent calls
- One-pager runbook for your ops team
- Full ownership with no license fees
