Affordable API Integration Development DevelopersAPI Integration
Hire senior developers who build integrations at a fixed price. Ship your API integration in 8-12 weeks with full ownership.
IRPR builds affordable API integrations for companies that need to connect their software to third-party services. We use Node.js, Python, and AWS Lambda to create REST and GraphQL APIs that sync data in real time.

Why affordable API integration development matters
A well-built API integration saves your team hours of manual work and prevents data errors.
IRPR has shipped over 200 API integrations for clients in 50 countries. Each integration is built by senior engineers who have done this before. We use proven patterns for authentication, error handling, and rate limiting.
Our fixed price model means you know the cost upfront. No hourly billing surprises. The average API integration project runs 8-12 weeks and costs $50K to $150K, depending on the number of endpoints and compliance requirements.
How IRPR differs from generic dev shops
Most agencies promise affordable API integration but deliver scope creep and buggy code.
Generic shops often assign junior developers, use hourly billing, and ignore security best practices. You end up paying more and waiting longer for a half-working integration.
IRPR gives you a fixed price, a senior-only team, and a clear roadmap. We handle authentication, logging, monitoring, and documentation as standard.
- Hourly billing with no cap
- Junior developers learning on your project
- No security review for API keys
- Poor error handling and retry logic
- No documentation or monitoring
- Scope creep after the contract is signed
- Fixed price agreed in the Roadmap phase
- Senior engineers with 10+ years experience
- Encrypted API key storage and rotation
- Exponential backoff and idempotency built in
- Auto-generated docs and Sentry monitoring
- Scope locked after Roadmap sign-off
Our process for affordable API integration development
We follow a four-phase process that guarantees on-time delivery and full code ownership.
The process starts with a 1-week discovery call where we define the integrations you need. Then we create a detailed Roadmap with a fixed price and timeline.
After you approve the Roadmap, we build the integration in 6-10 weeks, testing each endpoint against your target system. Finally, we deploy and hand over the source code.
What ships with every API integration project
Every delivery includes production-ready code, documentation, and operational tooling.
When we finish an integration, you get a complete package. No missing pieces. No hidden dependencies.
We also include a 30-day support period to handle any questions or edge cases after launch.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions
- API documentation generated from OpenAPI spec
- Sentry error tracking and alerts
- Logging with structured JSON logs
- Rate limit handling and retry logic
- Unit and integration tests with 90%+ coverage
- Deployment scripts for AWS or Azure
- Postman collection for manual testing
- 30-day post-launch support

Why teams hire us.
Fixed price, not hourly
Every API integration project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. You know the cost before we start.
Senior engineers only
Our team averages 12 years of experience. No juniors. Every engineer has built at least 10 production API integrations. You get a lead engineer who stays on your project from start to finish.
8-12 week delivery guarantee
We ship 98% of projects on time. Our process is designed for speed: clear Roadmap, 2-week sprints, and automated testing. If we miss the deadline, you pay nothing extra.
Full code ownership
You own 100% of the source code, documentation, and deployment scripts. No license fees. No vendor lock-in. You can take the code to any internal team or another agency.
Compliance built in
We build integrations that pass HIPAA, PCI-DSS, and SOC 2 audits. Our code includes encryption at rest and in transit, audit logs, and role-based access control. Compliance is not an afterthought.
Async-first collaboration
Our team works across time zones with daily async updates. You get a dedicated Slack channel and a weekly video call. No need to be in New York or San Francisco to work with us.
