API Integration Development StudioDevelopment Studio
We build custom API integrations that connect your software to everything. 200+ products shipped, fixed pricing, 8-12 week delivery.
IRPR is an API integration development studio that builds custom connectors, middleware, and third party integrations. We use Node.js, Python, Go, and cloud services on AWS, GCP, and Azure to connect systems like Salesforce, HubSpot, Stripe, and Shopify.
Every project starts with a 2-week Roadmap phase for $5K-$10K. Full MVP build takes 8-12 weeks and costs $80K-$250K. We handle compliance: HIPAA for healthcare, PCI-DSS for fintech, SOC 2 for SaaS.
We work with CTOs who need to integrate legacy ERP with a new SaaS product. Product managers who need a Stripe connector in 10 weeks. Founders who need to sync data between HubSpot and their custom app. Engineering leads who need a reliable API gateway for microservices.
Types of software we ship.
Custom REST API development
Build stateless REST APIs with OpenAPI specs, JWT auth, and rate limiting. Deployed on AWS API Gateway or Express.js.
Third party integration connectors
Pre-built connectors for Salesforce, HubSpot, Stripe, Shopify, QuickBooks, and 50+ other platforms. Each connector is customizable.
Middleware and API orchestration
API middleware that routes, transforms, and enriches data between systems. Uses Kafka or RabbitMQ for event-driven architectures.
GraphQL API development
GraphQL APIs with Apollo Server, schema stitching, and real-time subscriptions. Supports federated data from multiple sources.
SOAP to REST migration
Migrate legacy SOAP web services to modern REST APIs. Includes WSDL parsing, contract mapping, and backward compatibility testing.
Webhook system development
Build webhook delivery systems with retry logic, payload signing, and event logging. Handles 10,000+ events per hour.
API security and authentication
Implement OAuth 2.0, OpenID Connect, API keys, and mTLS. Includes rate limiting, IP whitelisting, and audit logging.
API documentation and SDK generation
Generate interactive API docs with Swagger/OpenAPI and client SDKs in Python, JavaScript, and Go. Automated with Redoc or Stoplight.

API integration development studio stats
IRPR delivers reliable, secure API integrations on time and on budget.
We have shipped 200+ products to clients in 50+ countries. Our on-time delivery rate is 98%. We maintain 99.9% uptime for our production integrations.
Typical API projects cost $80K-$250K and take 8-12 weeks to MVP. The Roadmap phase costs $5K-$10K and takes 2 weeks. We have built integrations for HIPAA-covered entities, PCI-DSS level 1 merchants, and SOC 2 compliant SaaS companies.
We use Node.js, Python, Go, and cloud services on AWS, GCP, and Azure to connect systems like Salesforce, HubSpot, Stripe, and Shopify.
Generic dev shop vs an API integration studio
Not all development teams understand API integration. IRPR builds integrations that work in production.
Generic dev shops often deliver fragile point-to-point integrations that break when one API changes. They lack compliance knowledge and skip security best practices like rate limiting and payload validation.
IRPR builds integrations with proper error handling, retry logic, and monitoring. We use API gateways for traffic management and implement OAuth 2.0 or mTLS for authentication. Every integration includes logging with Sentry and distributed tracing.
- No dedicated API engineers
- Fragile point-to-point connections
- No compliance (HIPAA, PCI, SOC 2)
- Missing error handling and retries
- No API monitoring or alerting
- Hourly billing with scope creep
- Senior API engineers with 10+ years each
- Event-driven integration with queues
- HIPAA, PCI-DSS, SOC 2 built in
- Retry logic with exponential backoff
- Sentry monitoring and PagerDuty alerts
- Fixed price from Roadmap phase
How our API integration development works
We follow a proven 4-phase process to deliver your custom integration on time.
Every project starts with an Idea phase where we define scope, risks, and compliance needs. Then we move to Roadmap for architecture and fixed price. Next is Product where we build and test. Finally Release with deployment and handover.
The Roadmap phase costs $5K-$10K and takes 2 weeks. You get a detailed specification, architecture diagram, and fixed price for the full build. This eliminates surprises.
What ships with every API integration project
Transparency is built into every delivery. You get the full package, not just code.
Every project includes source code in your private GitHub repo, CI/CD pipeline with GitHub Actions, and a staging environment for testing. We ship API documentation with OpenAPI specs and Postman collections.
All integrations include Sentry error monitoring, PagerDuty alerts for production incidents, and 30 days of post-launch support. We also train your team on maintaining the integration.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions
- API documentation with OpenAPI specs
- Postman collection for testing
- Sentry error tracking and monitoring
- PagerDuty alerts for production incidents
- Staging environment with test data
- Architecture diagram and runbook
- 30 days post-launch support
- Team training session (2 hours)
What we ship in this practice.
HubSpot to Salesforce data sync
Built a bi-directional sync between HubSpot CRM and Salesforce Sales Cloud using Node.js and Kafka. Reduced manual data entry by 12 hours per week for the sales team. Middleware handles deduplication and field mapping.
Stripe payment connector for a fintech platform
Developed a custom Stripe integration with webhook event handling, refund processing, and subscription management. Used Python with FastAPI on AWS Lambda. Achieved 99.9% uptime and processed $2M in transactions per month.
EHR to telehealth API integration
Integrated a legacy EHR system with a telehealth platform using HL7 FHIR standards. Built a middleware service in Go that translates data between SOAP and REST. Compliant with HIPAA. Reduced patient data entry time by 30%.
Shopify to ERP inventory sync
Built a real-time inventory sync between Shopify and NetSuite ERP using GraphQL and RabbitMQ. Handles 10,000+ products with variants. Eliminated overselling by syncing stock levels every 5 minutes. Reduced order errors by 90%.
API gateway for a microservices architecture
Designed and deployed an API gateway using Kong on AWS ECS. Routes traffic to 12 microservices, handles authentication with JWT, and enforces rate limiting at 1,000 requests per second. Improved system reliability from 95% to 99.9%.
Real estate MLS data feed integration
Built a data pipeline that ingests MLS listings from 3 different providers using REST APIs and webhooks. Python ETL jobs run on Airflow, load data into PostgreSQL, and serve via a GraphQL endpoint. Reduced listing update lag from 24 hours to 15 minutes.
Why teams hire us.
Fixed price, not hourly billing
Every API integration project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. You know the cost before we write a single line of production code.
Senior engineers only
Every team member has 10+ years of experience building APIs and integrations. You never get junior developers learning on your project. Our engineers have built integrations for Salesforce, Stripe, HubSpot, and 50+ other platforms.
Compliance built in from day one
We handle HIPAA, PCI-DSS, SOC 2, and GDPR compliance as part of the build. For API integrations, that means audit logging, encryption in transit and at rest, and identity management. No costly retrofits later.
You own the source code
All code is written in your private GitHub repo. You own 100% of the intellectual property. No licenses, no lock-in, no recurring fees. We do not use code generators or proprietary frameworks.
Monitoring and alerts included
Every integration ships with Sentry error tracking and PagerDuty alerts. We catch API failures, webhook timeouts, and data sync issues before they affect users. You get a production-ready system, not a prototype.
2-week kickoff from contract
We start the Roadmap phase within 2 business days of signing. No months-long sales cycles. You get a detailed spec and fixed price in 2 weeks. If you do not like the approach, you pay only the Roadmap fee and walk away.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
