Why Hire an Experienced API Integration Development Firm
A poorly built integration costs you hours of manual work and lost data every week.
IRPR has shipped 200+ integrations across 50+ countries. Our senior engineers use TypeScript, Node.js, Python, and Go to build integrations that handle 10,000+ transactions per hour. Every integration includes automated retry logic, dead-letter queues, and monitoring dashboards.
We write integration tests that cover error states and edge cases. Your team gets a Postman collection, Swagger docs, and a Grafana dashboard with alerting. No black boxes. No handoffs. Just working code in your repo.
The Difference Between IRPR and a Generic Dev Shop
Most agencies hand you code and disappear. IRPR hands you a production system that runs.
Generic dev shops write one-off scripts that break when a vendor updates their API. They skip error handling, leave no documentation, and charge hourly for every bug fix. You end up with fragile pipes that leak data and cost you sleep.
IRPR builds integrations with circuit breakers, rate limiters, and idempotent endpoints. We write tests that run in CI/CD. You get a Grafana dashboard that shows latency, error rates, and throughput. We fix bugs under the fixed price during the first 90 days.
- Hourly billing with no cap
- No error handling for API failures
- No monitoring or alerting
- No integration tests
- No documentation beyond comments
- One engineer who might quit
- Fixed price from day one
- Circuit breakers and retry logic
- Grafana dashboard with alerting
- Integration tests in CI/CD
- Swagger docs and Postman collection
- Senior engineers only, no junior staff
Our API Integration Development Process
We ship integrations in 8 to 12 weeks with a clear four-phase process.
Every integration starts with a two-week Roadmap phase where we map your data flows, define error handling, and fix the price. No surprises. No scope creep. You get a written plan with a timeline and a fixed cost.
After you approve the Roadmap, we build the integration in two-week sprints. You see working endpoints after the first sprint. We deploy to staging in week 6 and to production in week 10. The final two weeks cover load testing and monitoring setup.
What Ships With Every API Integration
You get more than just code. Every integration includes the full production toolchain.
Our experienced API integration development firm delivers source code, infrastructure-as-code, and monitoring in every project. Your team can deploy, debug, and extend the integration without calling us.
We use GitHub Actions for CI/CD, Terraform for cloud resources, and Datadog or Grafana for monitoring. Every integration includes a Postman collection with example requests and a Swagger spec that documents every endpoint.
- Source code in your GitHub repo
- CI/CD pipeline on GitHub Actions
- Cloud infrastructure on AWS or GCP
- Grafana dashboard with latency and error metrics
- Postman collection with 20+ example requests
- Swagger/OpenAPI spec for every endpoint
- Integration tests with 90%+ coverage
- Runbook for common failure scenarios
- 90 days of bug fixes under fixed price
- One hour of knowledge transfer session

Every integration gets a fixed quote during 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, no offshore handoffs. Every line of code is written by a senior engineer who has shipped production integrations for 50+ countries.
Production Monitoring Included
Every integration ships with a Grafana dashboard, alerting rules, and a runbook. You see latency, error rates, and throughput in real time. We fix issues under the fixed price for 90 days.
Compliance Built In
We build HIPAA, PCI-DSS, and SOC 2 compliant integrations by default. Data is encrypted in transit and at rest. Audit logs track every API call. Pass compliance reviews without rework.
You Own the Code
Every integration delivers full source code in your GitHub repo. No proprietary frameworks, no license fees, no lock-in. Your team can deploy, extend, and maintain the integration without us.
8 to 12 Week Delivery
Our process is designed for speed. Most integrations ship in 8 to 12 weeks. You see working endpoints after sprint one. Production deployment happens by week 10.
