Why hire an expert API integration development company
Building reliable API integrations requires deep knowledge of authentication, error handling, and data consistency.
IRPR has shipped over 200 integrations across 50 countries. Our engineers work with REST, GraphQL, SOAP, and gRPC. We handle OAuth 2.0, API keys, JWT, and custom auth flows. Every integration includes retry logic, rate limit handling, and idempotency to prevent duplicate data.
We test integrations with real API sandboxes and mock servers. Our CI/CD pipeline runs integration tests on every commit. You get a dashboard with uptime monitoring and error alerts. Average integration project ships in 10 weeks with a fixed price.
The difference between generic dev shops and IRPR
Not all development teams can build production-grade API integrations that handle edge cases and scale.
Generic dev shops often treat API integration as a simple task. They skip error handling, ignore rate limits, and deliver brittle code that breaks when the third-party API changes. You end up with manual data fixes and constant firefighting.
IRPR builds integrations that survive API version changes, network failures, and traffic spikes. We use circuit breakers, dead letter queues, and idempotency keys. Every integration ships with documentation and a runbook.
- No error handling for API timeouts
- Hardcoded API keys in source code
- No retry logic for failed requests
- Manual data sync scripts
- No monitoring or alerting
- Brittle code that breaks on API updates
- Retry logic with exponential backoff
- Secure credential storage with Vault
- Circuit breakers and dead letter queues
- Automated sync with idempotency keys
- Uptime monitoring and PagerDuty alerts
- API version migration strategy
Our API integration process in 4 phases
We follow a structured process from discovery to deployment so you know exactly what ships and when.
Phase 1 is discovery. We map your existing systems, identify integration points, and document data flows. You get a detailed integration specification with API endpoints, data models, and error scenarios.
Phase 2 is development. Our engineers build the integration in 2-week sprints. You see working code in your repo after the first sprint. We write unit tests, integration tests, and end-to-end tests.
What ships with every API integration project
Every integration project includes these deliverables by default. No hidden extras.
You get production-ready code in your private GitHub repo. The code includes authentication, error handling, logging, and monitoring. We also provide a deployment guide and a runbook for your operations team.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions
- Unit tests and integration tests
- API documentation with Swagger/OpenAPI
- Error handling with retry logic and dead letter queues
- Monitoring dashboard with Datadog or New Relic
- Alerting setup with PagerDuty or Slack
- Deployment guide and runbook
- 30 days of post-launch support
- Full ownership of all code and documentation
