Why you need a top API integration development vendor
A single broken API integration can cost your business thousands in lost revenue and support tickets.
IRPR has built 200+ integrations across 50 countries. We handle authentication flows, webhook retries, rate limiting, and data transformation. Each integration is tested against real API endpoints before deployment.
We use monitoring tools like Sentry and Datadog to catch failures in under 60 seconds. Our integrations achieve 99.9% uptime. When an upstream API changes, we update your integration within 48 hours.
Generic dev shop vs. IRPR as your top API integration vendor
Most development shops treat API integration as a side task. IRPR treats it as the core deliverable.
Generic shops often hardcode API keys, skip error handling, and ignore rate limits. You end up with broken syncs and angry users. IRPR builds integrations that recover from failures automatically.
We write unit tests for every API call. We use webhook retry queues with exponential backoff. Your data stays consistent even when third-party APIs go down.
- Hardcodes API keys in config files
- No retry logic on failures
- Ignores rate limit headers
- No monitoring or alerting
- No documentation for endpoints
- One-size-fits-all pricing
- Uses environment variables and secret managers
- Implements exponential backoff retries
- Respects rate limits with token buckets
- Sentry and Datadog monitoring included
- Full API integration documentation shipped
- Fixed price quoted in Roadmap phase
How IRPR builds your API integration in 4 phases
Every project follows our Idea-Roadmap-Product-Release framework. You know exactly what you get and when.
Phase 1 is the Idea phase where we map your data flows and identify every third-party API you need. Phase 2 is the Roadmap where we write a fixed-price contract.
Phase 3 is Product where senior engineers build and test each integration. Phase 4 is Release where we deploy, monitor, and hand over the code.
What ships with every API integration project
You don't just get working code. You get a complete system designed for production reliability.
Every integration includes a CI/CD pipeline that runs tests before deployment. We use GitHub Actions to automate builds and releases.
Your team gets a runbook that explains how each integration works, how to monitor it, and how to update it when APIs change.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions
- Unit tests for every API endpoint
- Sentry error tracking with alerts
- Datadog dashboards for integration health
- Full API documentation in Markdown
- Webhook retry queue with exponential backoff
- Rate limit handling with token bucket algorithm
- Environment variable configuration for secrets
- Deployment runbook for your DevOps team
What we ship in this practice.
Stripe payment integration for a subscription SaaS
IRPR connected a SaaS platform to Stripe for recurring billing, invoices, and webhook events. The integration reduced failed payments by 30% using automatic retry logic. Tech stack: Node.js, Stripe API, PostgreSQL.
Salesforce to HubSpot contact sync
We built a bidirectional sync between Salesforce and HubSpot that deduplicates contacts and updates records in real time. The client saved 15 hours per week on manual data entry. Tech stack: Python, Salesforce REST API, HubSpot API.
HL7 FHIR integration for a telehealth platform
IRPR integrated a telehealth app with Epic and Cerner EHR systems using FHIR R4. Patient data syncs in under 5 seconds with HIPAA compliance. Tech stack: Go, FHIR API, AWS.
Shopify to NetSuite inventory sync
We built a real-time inventory sync between Shopify and NetSuite that updates stock levels every 60 seconds. The client reduced overselling by 100%. Tech stack: Node.js, Shopify REST API, NetSuite SuiteTalk.
Twilio SMS integration for a logistics app
IRPR connected a logistics platform to Twilio for automated delivery notifications. The integration sends 50,000 SMS messages per month with 99.9% delivery rate. Tech stack: Python, Twilio API, Redis.
QuickBooks Online integration for an accounting app
We integrated a fintech app with QuickBooks Online to sync invoices, payments, and chart of accounts. The client reduced manual bookkeeping by 20 hours per month. Tech stack: Node.js, QuickBooks OAuth 2.0, MongoDB.
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.
Senior engineers only
IRPR hires senior engineers with 8+ years of experience. Every integration is built by someone who has shipped 10+ production integrations before.
8-12 week timeline
Most API integrations ship in 8-12 weeks from kickoff. We use agile sprints with 2-week cycles so you see working code early.
Full code ownership
You own all source code, documentation, and infrastructure configs. No licensing fees, no vendor lock-in, no recurring payments.
Compliance ready
IRPR builds integrations that pass HIPAA audits, PCI-DSS scans, and SOC 2 reviews. We document every data flow and access control.
Post-launch support included
Every project includes 30 days of post-launch support. We monitor integrations, fix any issues, and update code for API changes.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
