Best API Integration Development StudioDevelopment Studio
We build custom API integrations for SaaS platforms and enterprise systems. Ship your first integration in 8 weeks with fixed pricing.
IRPR specializes in API integration development. We build REST APIs, GraphQL endpoints, webhook services, and message queues using tools like RabbitMQ, Kafka, and MuleSoft. Every integration is designed for high availability and low latency.
A typical project ships in 8-12 weeks with fixed pricing from $80K to $250K. We support compliance standards including SOC 2, HIPAA, GDPR, and PCI-DSS. Each integration includes CI/CD pipelines, monitoring, and full documentation.
We work with CTOs needing to connect legacy systems to cloud platforms, product managers integrating third-party APIs like Salesforce or Stripe, and startup founders who need a single integration to close a major deal. Our clients range from funded startups to Fortune 500 enterprises.
Types of software we ship.
API Gateway Development
A unified entry point for all microservices. Includes rate limiting, authentication, and logging with Kong or AWS API Gateway.
Middleware Integration Platform
Connects multiple systems through a central middleware layer. Uses Node.js, Express, and Apache Camel for enterprise-grade routing.
Webhook Management System
Handles incoming and outgoing webhooks at scale. Built with Express, Redis, and a dead-letter queue for failed delivery retries.
Data Pipeline ETL Tool
Extracts, transforms, and loads data between databases and APIs. Uses Apache Airflow for orchestration and Python for transformations.
SDK / API Wrapper
A client-side library that wraps third-party APIs. Generated in multiple languages (Python, Ruby, TypeScript) with OpenAPI specs.
Custom CRM Connector
Bidirectional sync between Salesforce, HubSpot, or Zoho and internal systems. Maps fields, handles duplicates, and logs changes.
Real-Time Sync Engine
Syncs data between two systems in near real-time. Uses WebSockets, PostgreSQL LISTEN/NOTIFY, and event-driven architectures.
API Monitoring & Analytics Dashboard
Tracks API usage, latency, error rates, and endpoint performance. Built with React, Chart.js, and Prometheus for metrics.
We build for every business type.
Healthcare
Fintech
E-commerce
SaaS / Enterprise
Logistics
Proven API Integration Results
Our clients ship integrations faster with fewer bugs.
Every integration project at IRPR starts with a 2-week Roadmap phase where we define endpoints, data models, and error handling. We ship production-ready code in 8-12 weeks. Our 200+ integrations operate at 99.9% uptime across 50+ countries.
We use CI/CD pipelines (GitHub Actions) and automated testing (Jest, Supertest) to catch regressions early. Post-launch, we monitor with Sentry and Datadog. Clients typically reduce manual data entry by 10+ hours per week after their integration goes live.
Why IRPR Over a Generic Dev Shop
Most agencies overpromise and underdeliver on integrations.
A generic dev shop might say they can build any integration, but they lack repeatable processes. They often quote hourly rates, miss compliance requirements, and deliver undocumented code. Clients end up with broken pipelines and no one to call.
IRPR brings a structured approach: fixed price from day one, compliance expertise (HIPAA, SOC2, PCI-DSS), and a dedicated project manager. We deliver full documentation, code ownership, and a 6-month warranty on every integration.
- Vague timelines with no fixed date
- Hourly billing that spirals out of control
- No HIPAA or SOC2 compliance experience
- Sparse or missing documentation
- No post-launch support included
- Black box progress – you don't know the status
- Fixed price quoted in Roadmap phase (week 2)
- Senior engineers only, no junior devs
- Compliance-ready from day one (HIPAA, SOC2, PCI)
- Full documentation: OpenAPI specs, Postman collections
- 6-month warranty with ongoing support
- Daily async updates with clear milestones
Our API Integration Process
From audit to launch in 12 weeks, we follow a proven 4-step process.
Each integration is treated as a standalone product. We break the work into phases with clear deliverables. Clients receive weekly demos and can change priorities before development starts.
After launch, we provide a 30-day hyper-care period where we monitor every call and error. Then we hand off with a runbook and scheduled retros.
What Every Integration Project Includes
No surprises. Everything ships by default.
Every integration comes with a complete set of deliverables. You own everything – source code, documentation, and deployment scripts. We set up monitoring and alerts so your team can sleep soundly.
- Source code in your private GitHub repo
- CI/CD pipeline using GitHub Actions or GitLab CI
- OpenAPI 3.0 specification for every endpoint
- Postman collection with sample requests and responses
- Sentry error tracking configured for production
- Datadog or Prometheus dashboards for latency and error rates
- Load testing results (k6 or Artillary) showing 10,000 concurrent calls
- Integration tests with 95%+ code coverage
- Deployment runbook with rollback steps
- 6-month post-launch warranty with 48-hour response SLA
What we ship in this practice.
EHR to Billing System Integration
Built a bidirectional sync between Epic EHR and a custom billing system. Reduced manual claim entry by 12 hours per week. Used Node.js, FHIR API, and AWS SQS for message queuing.
Real-Time Inventory Sync Between Shopify and ERP
Synced inventory levels from Shopify to NetSuite every 30 seconds. Eliminated overselling and saved $20K monthly in cancellations. Used Python, Celery, and Redis.
Payment Gateway Abstraction Layer
Created a single API that routes payments to Stripe, Braintree, or Authorize.net based on region. Achieved 99.95% uptime and saved 40 hours of dev work per new gateway integration. Used Next.js, Express, and PostgreSQL.
Unified Customer View Across CRM and Marketing Tools
Merged data from Salesforce, HubSpot, and Mailchimp into a single REST API. Marketing teams got a 360-degree view and improved campaign targeting by 35%. Used GraphQL, Apollo, and MongoDB.
Automated Data Pipeline for Analytics
Built an ETL pipeline that pulls data from 12 third-party APIs into Snowflake every hour. Reduced reporting latency from 24 hours to 15 minutes. Used Airflow, dbt, and S3.
Multi-Tenant SaaS API Gateway
Developed a gateway that authenticates, rate-limits, and routes API calls for 50+ tenants. Each tenant gets isolated data and custom throttling rules. Used Kong, Lua scripting, and Postgres.
Why teams hire us.
Fixed Price, Not Hourly
Every project gets a fixed quote after the 2-week Roadmap. No hourly billing, no surprise invoices, no scope creep charges. You know the exact cost before we write a single line of code.
Compliance-Ready From Day One
We have built integrations for HIPAA-covered entities, PCI-DSS fintechs, and SOC 2 enterprises. Our engineers know encryption, audit logging, and data residency requirements.
Senior Engineers Only (No Juniors)
Every developer on your project has 8+ years of experience. We do not use junior devs to cut costs. You get architecture-level thinking from the first sprint.
Full Code Ownership
You own all source code, documentation, and deployment scripts. There is no licensing fee or lock-in. Fork the repo, self-host, or move to another agency anytime.
Async-First with Daily Overlap
Our team works across time zones but we maintain 4 hours of daily overlap with your team in US business hours. You get daily async updates via Slack and weekly video demos.
Post-Launch Warranty Included
Every integration comes with a 6-month warranty that covers bugs, edge cases, and integration failures. We respond within 48 hours and fix issues at no extra cost.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
