Top API Integration Development TeamAPI Integration
We build integrations that move data between your tools in real time. Fixed price, 8-12 week delivery, senior engineers only.
IRPR builds custom API integrations that connect SaaS applications, legacy systems, and cloud services. We work with REST, GraphQL, SOAP, gRPC, and webhook protocols using Node.js, Python, MuleSoft, and Dell Boomi.
Every integration ships in 8 to 12 weeks with a fixed price between $80K and $250K. We follow HIPAA, PCI-DSS, and SOC 2 compliance standards out of the box.
CTOs hire us to sync Salesforce with their ERP. Product managers need us to unify customer data across HubSpot, Stripe, and Zendesk. Operations leaders use us to automate workflows between NetSuite and Shopify.
Types of software we ship.

Why IRPR Is a Top API Integration Development Team
We have built over 200 integrations across 50 countries with a 98% on-time delivery rate.
Our team writes every integration from scratch using REST, GraphQL, or SOAP based on your source and target systems. We never use black-box middleware that locks you in. Each integration gets a dedicated tech lead who writes code alongside the team.
We test every endpoint with automated CI/CD pipelines that run against real staging environments. Postman collections and Swagger docs ship as part of the project. You own everything from day one.
How We Differ from Generic API Development Shops
Most integration projects fail because of unclear scope, junior talent, and hourly billing. IRPR fixes all three.
Generic shops start with a discovery phase that has no end date and bill hourly. They assign junior developers who learn your system on your dime. The result is a fragile integration that breaks on the next API update.
IRPR starts with a fixed-price Roadmap (week 2) that defines every endpoint, protocol, and error case. Senior engineers with 10+ years experience build the code. We guarantee the integration works for the first 90 days post-release.
- Unbounded discovery phase
- Hourly billing with no cap
- Junior developers assigned
- No compliance handling
- Minimal documentation
- No post-launch monitoring
- Fixed price from Roadmap (week 2)
- Senior engineers with 10+ years
- HIPAA, PCI, SOC 2 built in
- Swagger/OpenAPI docs shipped
- CI/CD with automated testing
- Sentry error tracking and uptime monitoring
Our API Integration Process: 4 Phases
Every integration follows a repeatable process that eliminates risk for both parties.
We designed our process around the fixed-price model. Each phase has clear deliverables, so you know exactly what you get and when you get it.
Most teams skip planning and go straight to code. We spend two weeks on discovery and architecture to map every data flow, authentication method, and error scenario.
What Ships with Every Integration Project
You don't just get code. You get a complete integration package that your team can run independently.
Every project includes everything needed to operate the integration in production. No hidden tooling costs, no license fees, no black-box platforms.
We deliver full source code in your private GitHub repo with a README that explains the integration architecture. You own everything and can modify it without us.
- Source code in your GitHub repository
- CI/CD pipeline on GitHub Actions or GitLab CI
- Postman collection with environment variables
- Swagger/OpenAPI documentation
- Sentry error tracking and alerting
- Uptime monitor setup (Pingdom or similar)
- Load testing report (k6 or Artillery)
- Deployment runbook for production rollback
- Data mapping spreadsheet for field transformations
- 90-day post-release support and bug fixes
What we ship in this practice.
Unified Patient Data Between Epic and Salesforce
We built a bi-directional HL7 FHIR integration that syncs patient demographics, appointments, and lab results. Manual data entry dropped from 10 hours per week to zero. Tech stack: MuleSoft, Epic FHIR API, Salesforce REST API, PostgreSQL.
Real-Time Payment Reconciliation for a Fintech Platform
Connected Stripe and Plaid with a custom accounting system to reconcile 50,000+ daily transactions. The integration reduced reconciliation time by 8 hours per day. Tech stack: Node.js, Stripe API, Plaid API, Redis, AWS Lambda.
Multi-Channel Order Sync for an Ecommerce Brand
Integrated Shopify, Amazon Seller Central, and ShipStation into a single order management flow. Order processing time dropped from 15 minutes to 30 seconds per order. Tech stack: Python, Shopify GraphQL, Amazon MWS, ShipStation API, Celery.
Automated Lead Enrichment for a SaaS Platform
Built a webhook pipeline that passes new leads from HubSpot through Clearbit and ZoomInfo before creating the CRM record. Lead qualification time reduced by 4 hours per week. Tech stack: Zapier, HubSpot API, Clearbit API, ZoomInfo API, Google Cloud Functions.
Real-Time Tracking Integration for a Logistics Company
Integrated FedEx, UPS, and USPS tracking APIs into a custom dashboard used by 200+ dispatchers. Package visibility improved from 60% to 99% within two weeks of deployment. Tech stack: Ruby on Rails, FedEx API, UPS API, USPS API, Sidekiq.
Content Syndication from CMS to Media Partners
Built a GraphQL API that pushes articles from a headless CMS (Contentful) to six media partners (Apple News, Google News, Facebook Instant Articles). Time to publish new content dropped from 2 days to 10 minutes. Tech stack: Node.js, Contentful API, Apollo GraphQL, AWS S3.
Why teams hire us.
Fixed price, not hourly
Every integration project gets a fixed quote during the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. If the API changes during the project, we absorb the cost.
Senior engineers only
We hire only engineers with 10+ years of experience. No juniors, no offshoring to low-cost centers. Your tech lead has built integrations for companies like Google, Amazon, and Stripe.
Compliance built-in
We integrate with HIPAA-covered entities using BAA-compliant data handling. For fintech we follow PCI-DSS Level 1. SaaS integrations meet SOC 2 Type II requirements. We document every compliance control.
99.9% uptime guarantee
Every integration we deploy comes with a 99.9% uptime SLA. We monitor endpoints with Sentry and Pingdom. If the integration fails, we respond within 30 minutes during business hours.
Full source code ownership
You own every line of code we write. No license fees, no ongoing royalties, no proprietary runtimes. The code lives in your GitHub repository from day one.
8 to 12 week delivery
We ship your first integration in 8 weeks or less. Complex multi-system integrations take up to 12 weeks. Every project comes with a calendar with milestones you can track.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
