Expert API Integration Development TeamAPI Integration
Connect your tools and data with an expert API integration development team. We ship secure, scalable integrations in 8-12 weeks.
IRPR builds production-ready integrations using REST APIs, GraphQL, webhooks, and tools like Postman, Swagger, and ngrok. We handle authentication (OAuth, API keys, JWT), error handling, rate limiting, and data transformation so your systems talk to each other reliably.
Every project ships in 8-12 weeks under a fixed price contract. Cost ranges from $50K to $150K depending on the number of endpoints and compliance requirements. We deliver with HIPAA, PCI-DSS, and SOC 2 safeguards where needed.
Typical buyers: SaaS founders who need to sync HubSpot with Salesforce, healthcare CTOs integrating EHR systems like Epic, fintech companies connecting Stripe to their accounting software, and logistics firms linking their ERP to carrier APIs.

Why You Need an Expert API Integration Development Team
Poor integrations cost time and money. A dedicated team avoids common pitfalls.
Manual data entry between systems causes errors and delays. One study found that integration issues cost enterprises an average of $5 million per year in lost revenue and labor. An expert API integration development team eliminates these gaps with reliable code.
IRPR has shipped over 200 integrations across 50 countries. Our team follows a proven roadmap: we map endpoints, write contract tests, implement with retry logic and monitoring, and deliver documentation. This process cuts debugging time by 40% compared to ad-hoc development.
The Difference Between IRPR and Generic Dev Shops
Not all teams can handle complex integrations. Here is what sets IRPR apart.
Generic agencies treat integrations as one-off tasks. They underestimate API limits, ignore error handling, and skip documentation. IRPR treats every integration as a product. We build it to scale and last.
Our senior engineers have experience with over 50 different API providers. We follow a standard integration checklist: authentication, rate limiting, retry logic, payload validation, logging, and monitoring. This approach reduces production incidents by 80%.
- Hourly billing with no cap
- No upfront API mapping
- Weak error handling (no retries)
- No automated tests for connectors
- Poor or missing documentation
- No post-launch monitoring
- Fixed price from the start
- Detailed API spec delivered in week 2
- Exponential backoff and retry logic
- Integration tests covering all endpoints
- Comprehensive integration documentation
- Sentry error tracking and uptime monitoring
Our Integration Development Process
We follow a four-phase process to deliver expert API integration development.
Phase 1 (Week 1-2): Roadmap. We map all endpoints, authentication methods, and data schemas. You get a detailed plan with timelines and fixed price.
Phase 2 (Week 3-8): Build. We write code with proper error handling, logging, and tests. You see progress in a shared repository and can test in staging.
What Ships with Every Integration Project
Every expert API integration development project includes these deliverables.
We believe in shipping working software with everything needed to run and maintain it. You don't have to chase us for documentation or code.
Every project includes these items by default. No add-ons or hidden fees.
- Source code in your private Git repository
- CI/CD pipeline with automated tests on GitHub Actions
- Integration test suite covering all endpoints
- API documentation (OpenAPI or markdown runbook)
- Error tracking setup with Sentry
- Uptime monitoring with Pingdom or Datadog
- Deployment scripts for your cloud (AWS, GCP, Azure)
- Secrets management using Vault or environment variables
- One month of post-launch support and bug fixes
- Knowledge transfer session with your team
What we ship in this practice.
HubSpot-Salesforce Bi-Directional Sync
We built a real-time sync between HubSpot and Salesforce for a B2B SaaS company. The integration handled 50K+ records daily and reduced manual data entry by 8 hours per week. Tech stack: Node.js, Salesforce REST API, HubSpot API, Redis for queuing.
Stripe Payment Gateway for Marketplace
For a fintech startup, we integrated Stripe Connect to process payments between buyers and sellers. The system handled identity verification, escrow, and instant payouts. Outcome: 30% faster checkout and 99.9% transaction success rate. Tech stack: Python, Stripe API, PostgreSQL, Celery.
EHR Data Exchange for Telehealth App
We connected a telehealth platform to Epic EHR using FHIR APIs. The integration pulled patient demographics and lab results in real time. Outcome: eliminated duplicate data entry for 200+ clinics. Tech stack: Java, FHIR R4, OAuth2, HL7 v2.
Shopify to ERP Inventory Syncing
We built a two-way sync between Shopify and NetSuite for a D2C brand. Inventory levels updated every 5 minutes, and orders flowed automatically. Outcome: 3x reduction in stockouts. Tech stack: Node.js, Shopify REST API, NetSuite SuiteTalk, Bull queue.
Shipping Carrier API Aggregator
For a logistics company, we created an API gateway that aggregated rates from FedEx, UPS, and DHL. The gateway normalized responses and cached results for 60 seconds. Outcome: 40% faster rate comparisons. Tech stack: Go, Redis, gRPC, Prometheus.
Custom Webhook Ingestion Service
A media platform needed to receive webhooks from 12+ partners (Slack, GitHub, Twilio, etc). We built a service with idempotency, retry, and dead-letter handling. Outcome: 100% webhook delivery and 95% reduction in support tickets. Tech stack: Python, FastAPI, AWS SQS, DynamoDB.
