We build custom API integrations that move your data where it needs to go. Get a fixed price quote in your second week.
IRPR builds professional API integration development services that connect your software to third-party platforms like Salesforce, Stripe, HubSpot, and Twilio. We use Node.js, Python, and Go to create fast, secure API middleware.
Every integration ships with a fixed price (starting at $80K) and a timeline of 8 to 12 weeks. You get real-time error logs, retry logic, and rate limit handling. Our builds comply with HIPAA, PCI-DSS, and SOC 2.
Companies hire us when their in-house team is too busy, their offshore vendor keeps missing deadlines, or they need a HIPAA-compliant integration for a healthcare client. Typical buyers are CTOs, product owners, and agency owners who need reliable API work done right the first time.
Build RESTful endpoints that sync data between your app and third-party services like Salesforce, Shopify, or QuickBooks via JSON over HTTPS.
Connect legacy enterprise systems like SAP, Oracle, or Microsoft Dynamics using SOAP protocols with XML payloads and WSDL definitions.
Create a single GraphQL endpoint that queries multiple data sources (PostgreSQL, MongoDB, Redis) with exact field selection for mobile apps.
Integrate Stripe, Braintree, or Adyen for payment processing. Handle webhooks, refunds, subscriptions, and PCI-DSS compliance in 10 weeks.
Sync contacts, deals, and activities between your app and Salesforce, HubSpot, or Zoho using OAuth 2.0 and bulk API endpoints.
Connect Shopify, WooCommerce, or BigCommerce to your ERP or 3PL system. Sync inventory, orders, and shipping statuses in real time.
Build HL7 FHIR or HIPAA-compliant APIs that connect EHR systems like Epic or Cerner to your telemedicine or analytics platform.
Deploy an API gateway using Kong or AWS API Gateway to rate-limit, authenticate, and route traffic across microservices and third-party APIs.
Our track record shows what professional API integration development services can deliver.
IRPR has completed over 200 product launches that relied on third-party API integrations. We maintain a 98% on-time delivery rate across all projects. Our clients span 50+ countries, from early-stage startups to Fortune 500 enterprises in New York, Los Angeles, and beyond.
Each integration is built with automated monitoring and error recovery. Our production APIs average 99.9% uptime. We use tools like Datadog, Sentry, and PagerDuty to detect and resolve issues before they affect your users.
Most development shops build one-off API calls. We build systems that last.
A generic developer writes a single endpoint to pull data from a third-party API. They test it manually, push it to production, and move on. When the third-party API changes its schema or rate limits your requests, your integration breaks and your team scrambles to fix it.
IRPR treats API integration as a product. We design for error handling, retry logic, rate limiting, and monitoring from day one. Our integrations include automated tests for every endpoint plus a runbook for the operations team. You get a system that works predictably even when the upstream API changes.
We follow a four-phase process that keeps your integration on time and on budget.
Every project begins with a discovery call where we map your data sources, endpoints, and business rules. By the end of week 2, you get a fixed price quote, a detailed technical design document, and a timeline. No scope creep, no surprises.
The build phase runs in two-week sprints. You see a working integration after the first sprint. We deploy to production in week 8 to 12, depending on complexity. After launch, we provide 30 days of production support to handle any edge cases.
Every integration includes these deliverables by default.
You get more than just working code. Every project ships with a production-ready deployment pipeline, monitoring tools, and documentation that your team can use for years. No hidden costs, no surprise handoff fees.
Our clients tell us the documentation and monitoring setup alone save them weeks of onboarding time when new developers join their team. Everything is designed to be maintained by any competent engineer, not just the person who built it.
We replaced a custom billing system with a Stripe Connect integration. The integration handles subscriptions, invoicing, and automatic tax calculation. Processing time dropped from 12 hours to 4 minutes per batch. Built with Node.js, PostgreSQL, and Stripe API.
We built a bidirectional sync between Salesforce and a custom analytics platform. Contacts, accounts, and opportunities update in real time via REST API and Platform Events. Reduced manual data entry by 15 hours per week. Built on Python, Celery, and Salesforce Bulk API.
We connected Shopify orders to a warehouse management system using GraphQL and webhooks. Inventory levels update every 5 minutes, order statuses sync automatically, and returns trigger restock workflows. Fulfillment accuracy rose from 94% to 99.7%. Built with Ruby on Rails, Sidekiq, and Shopify API.
We integrated a telemedicine platform with Epic using HL7 FHIR APIs. Patient demographics, appointment schedules, and clinical notes sync in real time. Compliance with HIPAA required end-to-end encryption and audit logging. Built with Go, FHIR R4, and AWS PrivateLink.
We added SMS notifications to a real estate CRM using Twilio's API. Agents receive automatic alerts for new leads, showing requests, and price changes. Message delivery rate is 99.8% with 2-second average latency. Built with Node.js, Redis, and Twilio Messaging API.
We built a sync between a bookkeeping app and QuickBooks Online via OAuth 2.0. Transactions, invoices, and vendor accounts reconcile daily. Customers can close their books 60% faster than manual entry. Built with PHP, Laravel, and QuickBooks Online API.
Every IRPR engineer has 10+ years of experience building production API integrations. We do not staff projects with junior developers or offshore teams. You work directly with the same senior engineer from design through deployment.
After the Roadmap phase (week 1-2), you get a fixed price quote covering the entire integration. No hourly billing, no surprise fees for scope changes, no budget overruns. The price you agree to in week 2 is the price you pay at launch.
Most single-API integrations ship in 8 weeks. Complex multi-API projects take up to 12 weeks. You see working endpoints after the first sprint (2 weeks). We maintain a 98% on-time delivery rate across all projects.
We build integrations that meet HIPAA, PCI-DSS, and SOC 2 requirements. We use encrypted transport (TLS 1.3), tokenized authentication (OAuth 2.0, JWT), and audit logging for every request. Your compliance team gets the paperwork they need.
All source code, test files, and documentation belong to you from day one. We deploy to your infrastructure, not ours. There are no licensing fees, no royalties, no recurring payments for the software we build.
Every integration ships with Datadog dashboards, Sentry error tracking, and PagerDuty alerting. You see request volumes, error rates, and latency in real time. Post-launch support covers 30 days of production monitoring and incident response.
Every engagement runs through the same four-stage pipeline. Predictable by design.
30-minute discovery call. No deck. We'll tell you honestly what it takes, how long, and how much.
