Leading API Integration Development AgencyAPI Integration
We build the bridges between your systems. 200+ products shipped with 98% on-time delivery.
IRPR is the leading API integration development agency. We connect your SaaS tools, databases, and legacy systems using REST, GraphQL, and WebSocket APIs. Every integration is built with Node.js, Python, or Go on cloud infrastructure like AWS Lambda or Azure Functions.
We ship production-ready integrations in 8-12 weeks with fixed pricing starting at $80K. Every project meets compliance standards: HIPAA for healthcare, PCI-DSS for fintech and ecommerce, and SOC 2 for SaaS. We handle OAuth, API keys, and custom middleware.
Companies hire IRPR when they need a single source of truth across Salesforce, HubSpot, Stripe, and their own platform. Our buyers are CTOs who have 3 disconnected systems, product managers who need real-time data sync, and compliance officers who require audit-ready integrations.

Why You Need a Leading API Integration Development Agency
Your CRM, ERP, and payment system don't talk to each other. We fix that.
IRPR has shipped 200+ integrations since 2016. We connect Salesforce to NetSuite, Stripe to QuickBooks, and HubSpot to custom databases. Every integration is built on a 4-phase process: discover, build, test, deploy.
Our clients save an average of 20 hours per week on manual data entry. One fintech client reduced payment reconciliation from 3 days to 15 minutes. We handle OAuth token refresh, rate limiting, and retry logic so your team doesn't have to.
How IRPR Delivers Better API Integrations
Most agencies hand you code and disappear. We hand you a running system with documentation.
Generic dev shops write code without understanding your business logic. They miss error handling, rate limits, and security checks. Then they charge hourly for every bug fix.
IRPR builds with test coverage above 90%, uses CI/CD pipelines with GitHub Actions, and deploys to your AWS or Azure account. You own the code from day one. No ongoing royalties, no black boxes.
- No API design review before coding
- Error handling is an afterthought
- No load testing on real data
- You pay hourly for every change
- No documentation delivered
- Security audit costs extra
- API contract review in week 1
- Retry logic and dead letter queues built in
- Load test with 10x your expected traffic
- Fixed price, no surprise invoices
- OpenAPI docs autogenerated
- HIPAA/PCI/SOC 2 compliance baked in
Our 4-Phase Integration Process
From discovery to deployment in 12 weeks. Here's exactly what happens each week.
We start with a 1-week discovery sprint where we map every API endpoint, sample real data, and write integration tests. No assumptions. No guesswork.
Then we build, test, and deploy in weekly sprints. You see working software every Friday. We handle the rest.
What Ships With Every Integration
You don't just get a connection. You get a production-ready system with everything included.
Every integration project delivers more than source code. We include infrastructure as code, monitoring dashboards, and a complete runbook. Your team can maintain and extend the integration without calling us.
We also provide 30 days of post-launch support. Any issue gets a same-day response. After that, you can sign a support retainer at $5K/month for ongoing maintenance and updates.
- Source code in your private Git repo
- CI/CD pipeline on GitHub Actions or GitLab
- OpenAPI 3.0 specification and docs
- Error logging with Sentry or Rollbar
- Dashboard with graphs on Datadog or CloudWatch
- Encrypted secrets stored in AWS Secrets Manager
- Runbook with deployment and rollback steps
- 30 days of post-launch support
- HIPAA/PCI/SOC 2 compliance evidence
- Load test report with latency and throughput
What we ship in this practice.
Salesforce to NetSuite Sync
A manufacturing company needed real-time order sync between Salesforce and NetSuite. We built a Node.js middleware on AWS Lambda that processes 50K orders per day. Error rate dropped to 0.1%.
Stripe to QuickBooks Reconciliation
A SaaS startup manually reconciled 500+ Stripe payments per day. We built an automated sync that matches payments to invoices in QuickBooks. Reduced reconciliation time from 15 hours to 12 minutes per week.
HubSpot to Custom CRM Integration
A real estate brokerage used HubSpot for marketing but a custom CRM for listings. We built a bidirectional sync using webhooks and scheduled jobs. Leads now appear in both systems within 5 seconds.
Epic EHR to Patient Portal
A healthcare network needed patient data from Epic to appear in their custom patient portal. We built a HIPAA-compliant FHIR integration using Azure API for FHIR. Patients see lab results within 1 hour of posting.
Shopify to 3PL Warehouse Sync
An ecommerce brand shipped 2000 orders per day but manually entered them into their warehouse system. We built a webhook relay that pushes order data to their 3PL api. Reduced shipping errors by 95%.
Learning Management System to SSO Provider
An edtech company needed to integrate their LMS with Azure Active Directory for single sign-on. We built an OAuth 2.0 flow using SAML 2.0 protocol. Logins went from 45 seconds to instant.
Why teams hire us.
Fixed price, not hourly
Every integration gets a fixed quote after the discovery sprint. You know the total cost before we build. No hourly billing means no surprise invoices at the end of the month.
You own the code
All code is written in your private repository from day one. We never use proprietary frameworks. You can take the integration to another team or maintain it yourself without paying IRPR a cent.
Compliance built in
We ship HIPAA, PCI-DSS, and SOC 2 compliant integrations as standard. Our middleware encrypts data at rest and in transit. We provide audit logs and compliance evidence with every project.
Real error handling
Every integration includes retry logic with exponential backoff, dead letter queues for failed messages, and automatic alerts when error rates exceed 1%. Your team gets paged before your customers notice.
Production monitoring included
We set up Datadog or CloudWatch dashboards that show latency, error rates, and throughput. You can see the health of every integration in real time. No blind spots.
Fast kickoff
You can start your integration project within 2 weeks of signing. We have senior engineers available immediately. No long sales cycle, no resource queue.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
