We build custom API integrations that connect your tools and automate workflows. Get a fixed price quote in week 2 and ship in 8-12 weeks.
IRPR builds custom API integrations that connect your SaaS tools, CRMs, ERPs, and databases. We use REST, GraphQL, webhooks, and middleware like Zapier, MuleSoft, and AWS Lambda to move data in real time.
Every integration ships with a fixed price quote in the Roadmap phase (week 2). Typical projects run 8-12 weeks and cost $80K-$250K. We handle HIPAA, PCI-DSS, and SOC 2 compliance for healthcare, fintech, and enterprise clients.
We work with CTOs who need to sync Salesforce with their internal ERP, product managers who want to connect Stripe to QuickBooks, and operations directors who need to automate data flow between 5+ tools. No hourly billing. No scope creep.

API integration development developers deliver real results
Our clients see measurable improvements in data accuracy and team productivity.
IRPR has shipped 200+ API integrations across 50 countries. One client reduced manual data entry by 8 hours per week after we connected their CRM to their accounting system. Another client cut order processing time from 3 days to 15 minutes with a custom Shopify-to-ERP integration.
We use a fixed price model so you know the cost upfront. In the Roadmap phase (week 2), we deliver a detailed spec with timeline and price. No surprises. No hourly billing.
Why IRPR beats generic dev shops for API integration
Most agencies bill hourly and deliver late. We do the opposite.
Generic dev shops often start coding without a clear spec. They bill by the hour, so scope creep costs you more. They rarely have compliance experience, so healthcare and fintech projects stall.
IRPR starts with a 2-week Roadmap phase where we document every endpoint, data model, and error case. You get a fixed price and a 12-week timeline. We have built integrations for HIPAA, PCI-DSS, and SOC 2 environments.

Our 4-phase process for API integration development
We follow a repeatable process that eliminates guesswork.
Every integration project at IRPR goes through four phases. The process is the same whether you need a simple webhook or a complex multi-system sync.
We ship working code every 2 weeks. You see progress in real time. No long silences.
What ships with every API integration project
You get more than just code. You get a production-ready system.
Every integration includes documentation, monitoring, and a deployment pipeline. You can hand it to your internal team or let us maintain it.
We use GitHub for source control, GitHub Actions for CI/CD, and Terraform for infrastructure. Everything is repeatable and auditable.
- Source code in your GitHub repo
- CI/CD pipeline with GitHub Actions
- API documentation (OpenAPI 3.0)
- Error tracking with Sentry
- Infrastructure as code (Terraform)
- Automated test suite (Jest, Mocha)
- Deployment runbook
- 30-day post-launch support
- SLA with 99.9% uptime guarantee
- Full ownership of all IP
