Generic dev shops vs IRPR: the affordable API integration development vendor difference
Most agencies charge by the hour and deliver late. IRPR gives you a fixed price and a firm timeline.
Generic dev shops often start with a vague estimate and bill you for every extra hour. They use junior developers who learn on your dime. You end up with fragile integrations that break when APIs change.
IRPR assigns senior engineers who have built integrations for Stripe, Salesforce, HubSpot, and 50+ other APIs. We write automated tests, handle edge cases, and document every endpoint. Your integration works on day one.
- Hourly billing with no cap
- Junior developers with 2 years experience
- No automated testing
- No error handling for rate limits
- No documentation
- Delays of 4-8 weeks
- Fixed price from $80K
- Senior engineers with 10+ years experience

How IRPR builds your API integration in 4 phases
We follow a structured process from idea to release. No guesswork, no scope creep.
Phase 1 is the Roadmap. In week 2, we deliver a detailed plan with architecture, endpoints, data models, and a fixed price. You approve before we build.
Phase 2 is Product. We build the integration in 2-week sprints. You see working code every sprint. Phase 3 is Release. We deploy to production with monitoring and alerting.
What ships with every API integration from IRPR
You get more than just code. Every project includes production-ready infrastructure and documentation.
We don't hand over a zip file and walk away. Every integration comes with automated tests, CI/CD pipelines, monitoring dashboards, and API documentation. You can maintain and extend the code yourself or hire us for ongoing support.
Our integrations are built to handle API changes. We use webhook retry logic, idempotency keys, and dead-letter queues. If an API changes its schema, your integration doesn't break silently.
- Source code in your GitHub or GitLab repo
- CI/CD pipeline with GitHub Actions or GitLab CI
- Automated integration tests with 90%+ coverage
- Error tracking with Sentry or Datadog
- API documentation with Swagger or Postman
- Monitoring dashboard with Grafana or CloudWatch
- Rate limit handling and retry logic
- Webhook receiver with idempotency keys
- Deployment scripts for AWS, GCP, or Azure
- 30 days of post-launch support
