Premium API Integration Development FirmIntegration Development
We connect your systems with secure, scalable APIs. 200+ integrations shipped in 12 weeks or less.
IRPR builds custom API integrations that connect your core systems. We use Node.js, Python, AWS Lambda, and Kafka to create reliable data pipelines between Salesforce, Stripe, HubSpot, and other platforms.
Every integration ships in 8-12 weeks with a fixed price between $80K and $250K. Our systems meet SOC 2, HIPAA, and PCI compliance standards. You own all source code and documentation.
CTOs hire IRPR to unify data across legacy and modern systems. Product managers engage us to add third-party API integrations to their SaaS apps. Enterprise architects trust us to migrate and modernize API ecosystems.

What makes a premium API integration firm different
Not every agency can build integrations that handle high volume and complex compliance.
IRPR has shipped 200+ API integrations across 50 countries. Our integrations process millions of transactions per day for fintech and healthcare clients. We use Apigee and Kong for API management and enforce rate limiting, retry logic, and circuit breakers on every connection.
We write integration tests that cover 95% of edge cases. Every pipeline includes CloudWatch and Datadog monitoring with alerts for latency and error rates. Our average time to detect and fix a production issue is under 15 minutes.
How IRPR beats generic dev shops on API integration
Standard agencies say they can integrate anything. The difference is in the details.
Generic shops use copy-paste code from open source repos and skip error handling. IRPR designs every integration with proper idempotency, retry policies, and idempotency keys from day one. We also document every endpoint in OpenAPI 3.0 format.
We assign a senior engineer with 10+ years of API experience to every project. That same engineer stays on through maintenance. You never get a junior who does not understand rate limits or OAuth flows.
- No dedicated API architect
- Scope creep leads to cost overruns
- No idempotency or error handling
- No monitoring until after launch
- Uses outdated SOAP without versioning
- Code not documented for handoff
- Senior engineer assigned full-time, 10+ years experience
- Fixed price locked after 2-week Roadmap phase
- Idempotency, retry, circuit breaker built in
- CloudWatch and Datadog alerts from day one
- REST and GraphQL with versioning (v1, v2)
- OpenAPI 3.0 docs shipped with every integration
Our 4-phase process for building your API integration
We follow a repeatable process that keeps scope fixed and delivery fast.
IRPR works in four phases: Idea, Roadmap, Product, Release. Each phase has clear deliverables and a fixed duration. No surprises.
For API integrations, the Roadmap phase (week 2) produces a full API contract, a data flow diagram, and a risk assessment for compliance.
Everything that ships with your premium API integration
You get more than just code. Every integration delivers these assets.
IRPR does not hide work behind closed doors. You get real visibility into every integration we build. All code, configs, and docs are sent to your repo as we write them.
- Full source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions and automatic tests
- OpenAPI 3.0 documentation
- Postman collection with sample requests
- Error logs via Sentry with alert rules
- Dashboards in Datadog for latency and error rates
- Retry and circuit breaker configuration
- API key rotation script and secrets manager setup
- One-pager runbook for on-call engineers
- 30-day post-launch monitoring and issue fix window

All developers have 10+ years of experience. No juniors, no offshore teams. Your lead engineer stays on the project from start through maintenance.
Compliance built in
We design integrations for HIPAA, PCI-DSS, and SOC 2 from day one. We include audit logs, encryption at rest and in transit, and role-based access.
Full code ownership
You get complete source code, deployment scripts, and documentation. No proprietary frameworks or hidden runtime licenses. You can take the code to any team.
Post-launch monitoring
We set up Datadog dashboards, Sentry alerts, and PagerDuty integration before launch. We monitor for 30 days and fix any issues that arise.
8-12 week delivery
Most integrations are built and deployed in 8-12 weeks. Our modular architecture and reusable connectors shorten development time without cutting corners.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
