Professional API Integration Development DevelopersAPI Integration
We build custom API integrations that connect your tools. Get a fixed-price quote in week 2 and ship in 8-12 weeks.
IRPR builds professional API integration development for companies that need to connect their software stack. We use Node.js, TypeScript, Python, and cloud-native services (AWS Lambda, Azure Functions) to create reliable integrations that handle authentication, rate limiting, and error recovery.
Every project ships with full source code, CI/CD pipelines, and monitoring. Timeline is 8-12 weeks for an MVP, with fixed pricing from $80K to $250K. We build to compliance standards like SOC 2 (SaaS), HIPAA (healthcare), and PCI-DSS (fintech).
Our buyers are CTOs scaling integrations across 5+ tools, product managers launching a new API-connected feature, and engineering leads replacing brittle point-to-point scripts with a maintainable integration layer.

What Professional API Integration Development Includes
Every integration project covers the full lifecycle from design to production monitoring.
IRPR treats API integration as a product, not a one-time script. We start with a Roadmap phase (week 2) that documents endpoints, authentication methods, error handling, and data mapping. You get a fixed price before any code is written.
The build phase delivers a scalable integration layer with retry logic, logging, and monitoring via Sentry and Datadog. We deploy to your cloud (AWS, GCP, Azure) with CI/CD using GitHub Actions. Post-launch, we provide 30 days of production support.
IRPR vs. Generic Development Shops
Not all API integration teams deliver the same quality. Here is how IRPR differs.
Generic shops often assign junior developers who learn on your dime. They use hourly billing, so scope creep costs you. Documentation is an afterthought, and you get no source code ownership.
IRPR assigns senior engineers with 10+ years of experience. We work on fixed price, not hourly. Every project includes full documentation, source code in your repo, and a 30-day warranty. We have built integrations for SOC 2, HIPAA, and PCI-DSS environments.
- Junior developers with 1-2 years experience
- Hourly billing with no cap
- No API documentation provided
- No monitoring or error tracking
- Source code not transferred
- No compliance knowledge
- Senior engineers only (10+ years)
- Fixed price quoted in week 2
- Full API documentation (OpenAPI/Swagger)
- Sentry error tracking + Datadog monitoring
- Source code in your GitHub repo
- Built for SOC 2, HIPAA, PCI-DSS
Our 4-Phase API Integration Process
We follow a repeatable process that reduces risk and speeds delivery.
Each phase has a clear deliverable. You know exactly what you get and when. No surprises.
The process works for any integration type: REST, GraphQL, SOAP, or custom protocols.
What Ships with Every Integration
Every project delivers a complete, production-ready integration. No loose ends.
You get everything needed to run and maintain the integration yourself. IRPR does not hold your code hostage.
- Source code in your private GitHub/GitLab repo
- CI/CD pipeline on GitHub Actions or GitLab CI
- API documentation (OpenAPI 3.0 or Swagger)
- Error tracking via Sentry with alerting
- Production monitoring with Datadog dashboards
- Unit and integration tests (Jest, Mocha)
- One-click deployment scripts (Terraform or Pulumi)
- Postman collection for manual testing
- 30 days of production support after launch
- Full architecture diagram and runbook

Why teams hire us.
Fixed price, not hourly
Every integration project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. You know the cost before we write a line of code.
Senior engineers only
Our team averages 12 years of experience. No junior developers learning on your project. Every engineer has shipped at least 5 production integrations using REST, GraphQL, or SOAP.
Full source code ownership
You own everything we build. Source code goes into your GitHub repo from day one. No proprietary frameworks, no license fees, no vendor lock-in. You can take the code to any team.
98% on-time delivery
Of 200+ projects, 98% shipped on schedule. We use a proven 4-phase process with weekly demos and transparent reporting. If we see a risk, you know about it before it becomes a problem.
Compliance built in (SOC 2, HIPAA, PCI)
We build integrations that pass audits. Our engineers know how to handle PHI (HIPAA), card data (PCI-DSS), and customer data (SOC 2). We use encryption, audit logs, and access controls by default.
8-12 week MVPs
Most integrations are production-ready in 8-12 weeks. We ship fast without cutting corners. You get a working integration with monitoring, documentation, and tests.
