Why Hire a Professional API Integration Development Firm
Most integrations fail because of poor error handling, rate limits, and data mismatch.
IRPR has built over 200 integrations across 50 countries. We use retry logic, exponential backoff, and idempotency keys to handle API failures. Our average integration ships in 8-12 weeks.
We support REST, GraphQL, SOAP, and gRPC. Every integration includes monitoring with Datadog and alerts via PagerDuty. We guarantee 99.9% uptime for the integration layer.
Generic Dev Shop vs Professional API Integration Firm
Not all developers understand API rate limits, pagination, and error handling.
A generic dev shop might copy a quick start guide and miss production edge cases. IRPR builds integrations that handle 10,000 requests per minute with proper backpressure.
We write integration tests for every endpoint. We use a staging environment that mirrors production. Every integration ships with a runbook for on-call engineers.

- Hourly billing
- Exponential backoff + retry

Our 4-Phase API Integration Process
We follow a repeatable process that de-risks every integration.
Phase 1 (Idea): We map your data model to the target API's schema. We identify authentication method (OAuth 2.0, API key, JWT) and rate limits. Deliverable: integration design document.
Phase 2 (Roadmap): We build a prototype that syncs 10 records end-to-end. We test error scenarios: network failure, invalid data, rate limit exceeded. Timeline: 2 weeks.
What Ships with Every API Integration
Every integration includes production-ready code, tests, and documentation.
We deliver source code in your GitHub repository. Every integration includes CI/CD pipelines, monitoring dashboards, and a runbook. We also provide Postman collections for manual testing.
Our team stays on call for 2 weeks after release. We fix any issues found during the monitoring period. After that, we offer ongoing support at a fixed monthly rate.
- Source code in your repo (GitHub, GitLab, Bitbucket)
- CI/CD pipeline with GitHub Actions
- Integration tests covering all endpoints
- Datadog dashboard with error rate and latency
- PagerDuty alerts for failures
- Postman collection for manual testing
- Runbook for on-call engineers
- OpenAPI / Swagger documentation
- Rate limit handling with exponential backoff
- 2-week post-release monitoring and support
