Why You Need the Best API Integration Development Team
Our team has shipped over 200 integrations across 50 countries.
IRPR has built 200+ products including API integrations for startups and enterprises. Our average project delivers in 12 weeks with 98% on-time rate. We handle everything from REST endpoints to GraphQL federations.
Each integration is tested for edge cases like network failures, rate limits, and data conflicts. We use automated retry logic and circuit breakers to ensure 99.9% uptime for your critical data flows.
Generic Development Shop vs. IRPR
Not all API integration teams deliver the same quality.
A generic dev shop might build your integration with minimal documentation and no monitoring. They bill by the hour and leave you with fragile code. You discover errors in production and pay extra for fixes.
IRPR builds integration layers with comprehensive tests, error tracking, and SLA-level monitoring. We deliver on a fixed price and include a 30-day warranty after launch. Your code is fully owned and deployed on CI/CD.
- Hourly billing with no cap
- No API error handling or retry logic
- Minimal documentation
- No automated testing for edge cases
- No post-launch monitoring included
- You don't own the source code architecture
- Fixed price from $80K with clear scope
- Built-in retry, circuit breakers, and logging
- Full API documentation with OpenAPI spec
- Automated unit, integration, and load tests
- Sentry error tracking and uptime alerts
- 100% code ownership in your repo
Our 4-Phase API Integration Process
From discovery to release, we follow a structured roadmap.
We start with the Idea phase to map every endpoint, data model, and business rule. This takes 1-2 weeks and produces a detailed API contract.
Then we build the integration in sprints, testing each connector against real third-party services. You get weekly demos and a staging environment.
What Ships with Every API Integration Project
You get more than just code — you get a fully managed integration layer.
All deliverables are included in the fixed price. No hidden fees or add-ons.

- OpenAPI 3.0 specification for every endpoint
- CI/CD pipeline with GitHub Actions or GitLab CI
- Automated unit test suite with 90%+ coverage
- Integration tests against sandbox environments
- Sentry error monitoring and performance tracking
- Postman collection for manual testing
- Rate limiting and retry logic with exponential backoff
- JSON logging with structured error context
- 30-day production support and warranty
