Why choose IRPR as your premium API integration development company
We have shipped over 200 integrations across 50 countries. Here is what our track record looks like.
IRPR has built API integrations for startups and enterprises in healthcare, fintech, ecommerce, and logistics. Our integrations handle millions of API calls per month with 99.9% uptime. We use Node.js, Python, and Go for backend services. Every integration includes error handling, retry logic, and monitoring with Sentry and Datadog.
We work in 12-week sprints with a fixed price. You know the cost and timeline before we write a line of code. No scope creep, no surprise invoices. Our senior engineers are based in the US, Europe, and Latin America, covering all time zones.
Generic dev shop vs IRPR: the premium API integration difference
Most development shops build fragile integrations that break when an API changes. IRPR builds integrations that last.
A generic dev shop might wire up a Stripe plugin in a weekend. But when your product scales, that plugin becomes a bottleneck. You need a team that designs for failure, handles rate limits, and logs every error.
IRPR builds every integration with a clean abstraction layer. If a third-party API changes, you update one adapter, not your entire codebase. We also provide Postman collections, integration tests, and documentation.
- No error handling for API timeouts
- Hardcoded API keys and endpoints
- No monitoring or alerting
- Single developer works alone
- No documentation or tests
- Hourly billing, no fixed price
- Retry logic with exponential backoff
- Environment variables and secrets management
- Sentry and Datadog monitoring included
- Senior engineer + QA reviewer on every project
- OpenAPI specs and integration tests shipped
- Fixed price from Roadmap phase
How we deliver your API integration in 12 weeks
Our process is designed for speed and clarity. You get a working integration in 12 weeks, not 6 months.
We start with a 1-week Roadmap phase. We map your data, document each API endpoint, and create a detailed integration spec. You get a fixed price and timeline before we write code.
Then we build in 2-week sprints. You see progress every 14 days. We deploy to staging, run integration tests, and get your sign-off before going live.
What ships with every API integration project
You own everything. No black boxes, no locked-in dependencies.
When we finish a project, you get a complete, production-ready integration. Not a prototype. Not a proof of concept. A real system that handles errors, logs requests, and scales with your business.
We also give you the tools to maintain and extend the integration yourself. Every component is documented and tested.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions
- Sentry error tracking and Datadog monitoring
- OpenAPI 3.0 specification for all endpoints
- Postman collection with sample requests
- Integration tests covering 90%+ of scenarios
- Environment-based configuration (dev, staging, prod)
- Rate limiting and retry logic
- Documentation with architecture diagram
- 30 days of post-launch support
