IRPR has shipped 200+ API integrations across 50 countries. Here are the numbers.
Our integrations average 99.9% uptime. We use retry logic with exponential backoff, circuit breakers, and dead-letter queues to handle API failures. Every integration includes a monitoring dashboard with error alerts.
We deliver in 8-12 weeks with a fixed price. Our team of senior engineers handles the entire lifecycle from design to deployment. We own the code and the documentation.
Most agencies build integrations that break when APIs change. IRPR builds integrations that last.
We use schema validation, versioned endpoints, and automated tests to catch breaking changes before they affect your users. Our integrations include a fallback mode that keeps your system running when a third-party API goes down.
We also provide a developer portal with API documentation, SDKs, and sample code. Your team can maintain and extend the integration after we hand it over.
We follow a 4-phase process that takes 8-12 weeks from kickoff to deployment.
Every project starts with a 2-week Roadmap phase where we define the integration scope, data model, and error handling strategy. We deliver a fixed price quote at the end of this phase.
After you approve the Roadmap, we build the integration in 6-10 weeks. We deploy to staging, run integration tests, and then push to production with a rollback plan.
You get more than just code. Every integration includes these deliverables.
We ship source code in your private GitHub repo. You own everything. No licensing fees, no vendor lock-in.
We also provide a deployment guide, a runbook for on-call engineers, and a 1-hour training session for your team.

We connected the app to Epic and Cerner using HL7 FHIR. Patient data syncs in under 2 seconds. Reduced manual data entry by 8 hours per week. Tech stack: Python, FHIR, AWS Lambda, RDS.
We built a bidirectional sync between the platform and Salesforce. Listings, contacts, and deals update in real time. Tech stack: Ruby on Rails, Salesforce REST API, Sidekiq, Redis.
We connected Shopify, Amazon, and a warehouse management system. Inventory levels update across all channels every 5 minutes. Tech stack: Node.js, Shopify API, Amazon SP-API, MongoDB.
We integrated with FedEx, UPS, and a custom TMS. Real-time rate quotes and label generation. Tech stack: Go, FedEx API, UPS API, PostgreSQL, RabbitMQ.
We connected the CMS to Mailchimp and Klaviyo. New subscribers are added to segmented lists automatically. Open rates increased by 15%. Tech stack: Python, Mailchimp API, Klaviyo API, Celery.
Every 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 line of code.
Every engineer at IRPR has 8+ years of experience. We do not hire juniors or outsource. Your integration is built by someone who has shipped 20+ integrations before.
We build integrations that pass HIPAA, PCI-DSS, SOC 2, and FERPA audits. We handle encryption, access controls, and audit logging. No retrofitting compliance after launch.
We ship source code in your private repository. No licensing fees, no ongoing royalties. You can modify, maintain, or sell the integration without asking permission.
Rate limiting, retry logic, error handling, monitoring, and documentation are included in every project. Your integration works when third-party APIs change or go down.
We can start within 1-2 weeks of signing. Most integrations ship in 8-12 weeks. We run a 30-day warranty after launch to fix any issues for free.
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.
