Why you need an API integration development partner
Building and maintaining API integrations in-house takes time and expertise most teams don't have.
IRPR has shipped over 200 integrations across 50 countries. Our senior engineers write every line of code in your repo with full CI/CD pipelines. We handle authentication, rate limiting, error handling, and data mapping so your team can focus on core product features.
We work with REST, GraphQL, SOAP, and webhooks. Every integration includes monitoring with Sentry and logging with Datadog. We test each endpoint with Postman and write integration tests in Jest. Your data stays secure with encryption in transit and at rest.
Generic dev shops vs IRPR as your API integration partner
Most agencies treat API integration as an afterthought. IRPR builds it as a core product feature.
Generic dev shops often use copy-paste code and skip error handling. They don't test edge cases or monitor production integrations. You end up with broken syncs and data loss.
IRPR treats every integration as a first-class feature. We write unit tests, integration tests, and set up monitoring from day one. Your team gets full documentation and a runbook for each connection.

Our API integration process in 4 phases
We follow a structured process to deliver your integration on time and on budget.
Every project starts with a 2-week Roadmap phase where we define endpoints, data models, and error handling. We map out authentication flows and rate limits. You get a fixed price and timeline before any code is written.
After approval, we build the integration in 6-10 weeks. We write tests, set up monitoring, and deploy to staging. You review each endpoint before we go live. We handle all compliance requirements for HIPAA, PCI-DSS, or SOC 2.
What ships with every API integration
Every integration includes these deliverables by default.
You own all code from day one. We write it in your repository with your CI/CD pipeline. No black boxes, no proprietary frameworks.
Each integration comes with a runbook that explains how to restart, debug, and extend the connection. Your team can maintain it without us.
- Source code in your GitHub or GitLab repo
- CI/CD pipeline with GitHub Actions or GitLab CI
- Unit tests with Jest (90%+ coverage)
- Integration tests with Postman
- Sentry error tracking configured
- Datadog performance monitoring
- API documentation with Swagger or Postman
- Runbook with troubleshooting steps
