Why choose an expert REST API development company
Building a REST API that scales, stays secure, and integrates with your stack requires deep experience.
IRPR has shipped over 200 REST APIs for clients in 50+ countries. Our APIs handle millions of requests per day with 99.9% uptime. We use OpenAPI 3.0 for documentation, JWT and OAuth 2.0 for authentication, and automated CI/CD pipelines with GitHub Actions.
Every API we build includes rate limiting, error handling, logging (Sentry), and monitoring (Datadog). We write integration tests with Postman and unit tests with Jest. Our APIs are designed to be consumed by mobile apps, web apps, and third-party services.
Generic dev shop vs expert REST API development company
Not every agency builds APIs that are secure, documented, and production-ready.
Generic dev shops often skip API documentation, ignore rate limiting, and use weak authentication. They deliver code that works locally but fails under load. IRPR builds APIs that are designed for production from day one.
We follow a structured process: Roadmap (week 2) defines endpoints, data models, and auth strategy. Product phase builds the API with tests and docs. Release phase deploys with monitoring and a 30-day warranty.
- No OpenAPI documentation
- No rate limiting or throttling
- Basic JWT without refresh tokens
- No integration tests
- No monitoring or alerting
- No compliance (HIPAA, PCI-DSS)
- OpenAPI 3.0 docs auto-generated
- Rate limiting with Redis and Nginx
- OAuth 2.0 with refresh tokens
- Postman integration tests + Jest unit tests
- Sentry error tracking + Datadog monitoring
- HIPAA, PCI-DSS, SOC 2 compliant
Our REST API development process
We follow a 4-phase process that delivers a production-ready API in 8-12 weeks.
Phase 1 (Idea) is a 1-week discovery where we map your data model, endpoints, and auth requirements. Phase 2 (Roadmap) produces a detailed API specification with OpenAPI 3.0, a timeline, and a fixed price.
Phase 3 (Product) is the build phase. We write code, tests, and documentation in parallel. Phase 4 (Release) deploys the API to AWS or GCP with CI/CD, monitoring, and a 30-day warranty.
What ships with your REST API
Every API project includes these deliverables by default.
You get full ownership of the source code, documentation, and infrastructure. No black boxes. No vendor lock-in.
We deploy on AWS or GCP using Terraform for infrastructure as code. You can take over or we can manage it.
- Source code in your GitHub/GitLab repo
- OpenAPI 3.0 documentation (Swagger UI)
- CI/CD pipeline with GitHub Actions
- Postman collection with integration tests
- Jest unit tests with 80%+ coverage
- Sentry error tracking
- Datadog monitoring dashboard
- Rate limiting with Redis
- OAuth 2.0 or JWT authentication
- Deployment scripts (Terraform + Docker)
