Experienced API Integration Development ServicesAPI Integration
We connect your systems with third-party APIs in 8-12 weeks. Fixed pricing from $80K with no surprises.
IRPR builds experienced API integration development services that connect your business applications using RESTful APIs, GraphQL, WebSockets, and Webhooks. We handle oAuth2 authentication, rate limiting, error handling, and retry logic out of the box.
Every project ships in 8-12 weeks with a fixed price ranging from $80K to $250K. We build for compliance standards including HIPAA, PCI-DSS, SOC 2, and GDPR — so your integrations meet regulatory requirements from day one.
We work with CTOs unifying SaaS tools, product managers integrating payment gateways, healthcare IT directors connecting EHR systems, and ecommerce operators syncing inventory across multiple platforms. These buyers choose IRPR for real expertise, not promises.
Types of software we ship.
Payment gateway integration
Connect Stripe, Braintree, or Adyen to your checkout flow with idempotency keys, webhook signing, and PCI-DSS compliance.
CRM integration (Salesforce, HubSpot)
Sync contacts, deals, and activities bi-directionally using REST APIs and bulk data jobs. Handle 1M+ records daily.
ERP integration (SAP, Oracle, NetSuite)
Bridge legacy ERP systems using SOAP, XML, and flat files. Maintain data consistency with retry logic and audit logs.
Ecommerce platform integration (Shopify, Magento)

Expose COBOL or mainframe data through RESTful wrappers. Use message queues (RabbitMQ) for reliable data transfer.
Data warehouse integration (Snowflake, BigQuery)
Stream data from operational systems into your data lake with incremental loads via REST or gRPC endpoints.
Cloud service integration (AWS, Azure, GCP)
Automate cloud provisioning and monitoring using SDKs and API gateways. Implement IAM roles, MFA, and CloudWatch alerts.

Why experienced API integration development services matter
Our team has shipped over 200 integrations across 50 countries with a 98% on-time record.
APIs are the backbone of modern business. When they break, orders fail, data silos grow, and teams waste hours fixing connection issues. IRPR builds integrations that handle errors, retry failures, and scale to thousands of requests per second.
We use proven patterns: circuit breakers, exponential backoff, idempotency keys, and webhook signature verification. Your systems stay consistent even when networks timeout or upstream APIs go down.
Generic dev shop vs IRPR
Most agencies build APIs that break under load. We build for scale from day one.
A typical dev shop writes endpoints that work in demo but fail under traffic. They skip rate limiting, ignore error handling, and deliver undocumented code. You end up with technical debt and surprise hours.
IRPR treats every integration as a production system. We ship with monitoring, retry logic, full documentation, and a fixed price. No surprise invoices, no broken connections.

Our API integration development process
We follow a 4-phase approach that delivers production-ready integrations on time and on budget.
Every integration starts with a deep discovery phase where we map your data flows, auth methods, and failure scenarios. Then we architect the solution, build it iteratively, and ship with full observability.
You see progress every week. We deploy to staging by week 6 and production by week 12. No hidden delays, no scope creep.
What ships with every API integration
Every integration includes these deliverables by default. No add-ons, no extras.
We believe in shipping complete systems. Every integration comes with monitoring, logging, and alerting so you know the health of your connections in real time.
- Source code in your Git repo (GitHub/GitLab/Bitbucket)
- CI/CD pipeline (GitHub Actions or GitLab CI)
- Sentry error tracking with alerts
- Postman collection for all endpoints
- OpenAPI 3.0 documentation
- Unit tests covering >90% of code
- Integration tests for each data flow
- Grafana dashboards for API health & latency
- Retry logic with exponential backoff
- Webhook signature verification
What we ship in this practice.
Payment gateway integration for ecommerce
IRPR connected a Shopify store to Stripe and Adyen with idempotent payment retries and webhook reconciliation. Outcome: reduced payment failures by 40% and saved the team 15 hours/week on manual reconciliation. Tech stack: Node.js, Stripe SDK, Adyen API, Redis queue.
CRM integration for real estate
We built a bidirectional sync between a real estate CRM and MLS listings using REST APIs and webhooks. Outcome: automated lead capture from 6 sources, saving 10 hours/week per agent. Tech stack: Python, FastAPI, PostgreSQL, HubSpot API.
Healthcare API for telehealth platform
IRPR integrated a telehealth app with Epic EHR using HL7 FHIR APIs. Outcome: eliminated manual chart entry for 200+ providers, saving 8 hours/week per provider. Tech stack: .NET Core, FHIR R4, Azure API for FHIR, HIPAA compliance.
SaaS integration for multi-tenant app
We built a unified API gateway that connects a multi-tenant SaaS to 15 third-party tools (Slack, Jira, Salesforce, etc.). Outcome: reduced customer onboarding from 4 weeks to 2 days. Tech stack: Go, GraphQL, Kong Gateway, Redis.
Supply chain API for logistics
IRPR integrated a freight aggregator with 5 major carriers (UPS, FedEx, DHL, etc.) using their SOAP and REST APIs. Outcome: reduced quote retrieval time from 30 seconds to 200ms per search. Tech stack: Java, Spring Boot, ActiveMQ, Docker.
Data pipeline for analytics platform
We built a streaming data pipeline that pushes ecommerce orders into Snowflake in near-real time using Kafka and REST endpoints. Outcome: reporting latency dropped from 24 hours to 2 minutes. Tech stack: Python, Kafka, Snowpipe, BigQuery, dbt.
