Professional API Integration Development CompanyAPI Integration
We build custom API integrations that connect your systems. Ship production-ready integrations in 8-12 weeks with fixed pricing.
IRPR builds professional API integrations that connect your SaaS tools, legacy systems, and third-party services. We use Node.js, Python, Kafka, and cloud-native patterns to handle REST, GraphQL, SOAP, and WebSocket protocols.
A typical integration ships in 8-12 weeks with a fixed price of $80K to $250K. Every project meets HIPAA, PCI-DSS, or SOC 2 compliance when required. We build reusable integration frameworks that cut later development by 40%.
CTOs hire us to replace brittle point-to-point integrations. Product managers use us to launch platform integrations that increase retention. Operations leads rely on us to automate data flow between ERP, CRM, and logistics systems.

Why hire a professional API integration development company
IRPR delivers API integrations that work reliably at scale, with clear timelines and budgets.
Most internal API integrations fail because teams underestimate complexity. Rate limits, authentication changes, error handling, and data consistency all need purpose-built code. We solve this with a reusable integration framework that handles these patterns out of the box.
Our clients choose us because we ship on time and on budget. Every integration includes monitoring, automated testing, and full documentation. We have built over 200 integrations across 50 countries, from healthcare to fintech.
The difference between generic dev shops and IRPR
You get more than code. You get a partner who owns the outcome.
Generic agencies charge by the hour and let scope creep blow your budget. They assign junior developers who learn on your project. They treat compliance as an afterthought.
IRPR operates differently. We give you a fixed price after understanding your requirements. Senior engineers with 10+ years experience build your integration. We bake compliance into every step.
- Hourly billing with no cap
- No dedicated project manager
- No compliance expertise
- Reinvents the wheel each time
- No post-launch support
- No code ownership guaranteed
- Fixed price from the Roadmap phase
- Dedicated senior engineers with 10+ years experience
- Built-in compliance (HIPAA, PCI-DSS, SOC 2)
- Reusable integration framework cuts dev time by 40%
- 1-year warranty on all integrations
- Full source code ownership in your repo
Our 4-phase process for API integration development
We break every project into four phases so you see progress every two weeks.
Each phase has a clear deliverable and go/no-go decision. You always know what you are getting and when.
We use agile sprints with daily standups and weekly demos. This keeps the project on track and gives you early access to working integrations.
What ships with every integration project
Every deliverable is production-ready from day one.
We do not hand over just a code drop. Each project comes with the tools your team needs to operate and extend the integration. All assets are in your control.
- Source code in private GitHub repo
- CI/CD pipeline with GitHub Actions
- Postman collection with all endpoints
- API documentation in Swagger / OpenAPI
- Secure credential storage (HashiCorp Vault)
- Error monitoring with Sentry
- Uptime monitoring with Datadog
- Integration health dashboard
- Unit and integration tests with 90%+ coverage
- Deployment scripts for AWS / GCP / Azure
What we ship in this practice.
Salesforce-to-ERP data sync
Connected Salesforce with NetSuite ERP for a manufacturing company. Reduced manual order entry by 15 hours per week using MuleSoft and Kafka.
Stripe-to-QuickBooks payment reconciliation
Automated payment reconciliation for a fintech startup. Cut month-end close from 5 days to 4 hours using Plaid and Stripe APIs.

Real-time booking integration for a travel platform
Connected a travel agency's booking system with Sabre and Amadeus APIs. Enabled real-time availability and reduced booking time by 60% using GraphQL and WebSockets.
Logistics carrier integration for a 3PL company
Integrated a warehouse management system with UPS, FedEx, and DHL APIs. Automated label generation and tracking, cutting manual effort by 20 hours per week using Python and Flask.
Why teams hire us.
Fixed-price from day one
We deliver a flat quote after the 2-week Roadmap phase. No hourly billing, no surprise invoices. Our clients see exactly what they pay before we write a line of code.
Senior engineers only
Every project is built by a lead engineer with 10+ years experience. No junior developers, no offshore teams. Our average seniority is 12 years.
Compliance built into every integration
We handle HIPAA, PCI-DSS, and SOC 2 as standard. Each integration includes encryption, audit logs, and vulnerability scanning. No separate compliance project needed.
We own the timeline
We ship 98% of projects on time. Our sprint-based approach with weekly demos keeps you in the loop. We tell you when something slides before it happens.
Full code ownership
You own the entire codebase from day one. Source code lives in your repository. We do not license or rent any software we build for you.
Post-launch support included
Every project includes a 1-year warranty on all integrations. We monitor uptime, fix bugs, and provide 48-hour response for critical issues. Extended support available at $5K/month.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
