Why hire affordable API integration development consultants
Building integrations in-house takes months and costs more than you expect.
Most engineering teams underestimate the effort to handle authentication, rate limiting, error handling, and webhook retries. A single Stripe integration can take 4-6 weeks if your team has never built one before. IRPR has built over 200 integrations across 50+ countries, so we ship in 12 weeks or less.
We use a fixed price model that starts at $80K. You know the cost before we write a line of code. Every integration includes automated tests, monitoring with Sentry, and a CI/CD pipeline on GitHub Actions. No surprise invoices, no hourly billing.
Generic dev shops vs IRPR for API integration
Not all consultants deliver the same quality. Here is what sets IRPR apart.
Generic dev shops often quote hourly rates and let scope creep inflate your budget. They skip error handling and monitoring, leaving you with broken integrations at 2 AM. IRPR builds production-ready integrations with retry logic, dead-letter queues, and 24/7 monitoring from day one.
We also handle compliance out of the box. If you need HIPAA, PCI-DSS, or SOC 2, we include the required logging, encryption, and access controls in the fixed price. No add-ons, no surprises.
- Hourly billing with no cap
- No automated tests for API endpoints
- No error monitoring or alerting
- No compliance documentation
- Code ownership unclear
- No post-launch support included
- Fixed price from $80K
- Automated test suite with Postman and Jest
- Sentry error tracking and PagerDuty alerts
- HIPAA, PCI-DSS, SOC 2 compliance built in
- Full source code ownership
- 2 weeks of post-launch support included
Our 4-phase process for API integration
We follow a structured process that delivers a working integration in 12 weeks.
Every project starts with a 2-week Roadmap phase where we map every endpoint, authentication method, and data schema. You get a fixed price and timeline before we build anything.
After the Roadmap, we build the integration in 8-10 weeks with weekly demos. You see progress every Friday. No black boxes, no waiting months for a first look.
What ships with every API integration project
You get more than just code. Every delivery includes these 10 items.
We believe in full transparency. When the project ends, you own everything and can run the integration without us. No lock-in, no recurring fees.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions
- Automated test suite with 90%+ coverage
- Sentry error tracking and alerting
- API documentation in Swagger/OpenAPI
- Postman collection for manual testing
- Deployment runbook with rollback steps
- Compliance documentation (HIPAA/PCI/SOC 2)
- 2 weeks of post-launch support
- Full ownership of all code and configs
What we ship in this practice.
