We build custom API connectors and middleware for your SaaS, fintech, or logistics platform. Ship in 8-12 weeks with a fixed price.
IRPR builds custom API integrations, connectors, and middleware for companies that need to connect their software to third-party services. We use REST, GraphQL, Webhooks, and message queues to handle data sync, authentication, and error handling.
Every project ships in 8-12 weeks with a fixed price ranging from $80K to $250K. We handle compliance like PCI-DSS for payments, HIPAA for healthcare, and SOC 2 for SaaS platforms.
Who hires us: CTOs who need to integrate Stripe, Salesforce, or ERP systems; product managers launching a marketplace that connects dozens of APIs; and compliance officers who require secure data pipelines between health systems and insurance gateways.
Build a payment connector that processes up to 10,000 transactions per minute using Stripe, Braintree, or Adyen with idempotency and retry logic.
Synchronize contacts, deals, and activities between Salesforce, HubSpot, and Zoho. Handle field mapping, deduplication, and change tracking.
Connect NetSuite, SAP, or Microsoft Dynamics to your platform. Map complex data models for invoices, purchase orders, and inventory.
Build a lightweight middleware layer in Node.js or Go that routes requests, transforms payloads, and manages auth between services.
Design and implement an API gateway with rate limiting, caching, authentication, and logging using Kong or AWS API Gateway.
Create a webhook orchestration service that delivers events to multiple endpoints, retries on failure, and logs delivery status.
Implement single sign-on with OAuth2, SAML, or OpenID Connect. Integrate with Okta, Azure AD, or Auth0 for enterprise users.
Build connectors for Shopify, WooCommerce, or BigCommerce to sync products, orders, and customers with your ERP or inventory system.
We have built over 200 integrations across 50+ countries.
Each integration is designed for reliability and scalability. Our team follows a standard API integration pattern: authentication, data model mapping, error handling, and monitoring.
We use tools like Swagger/OpenAPI, Postman, and custom test harnesses to validate every endpoint. Our middleware handles rate limiting, retries, and idempotency out of the box.
Most agencies charge by the hour and miss deadlines. We deliver fixed-price, on-time integrations.
Generic dev shops often leave you with fragile code, no documentation, and no ongoing support. IRPR builds reusable, documented connectors that you can maintain yourself.
We also include monitoring dashboards, error alerts, and a CI/CD pipeline for your API integrations.
From idea to production in 8-12 weeks.
Phase 1: Discovery and API mapping. We document every endpoint, authentication method, and data model of your target APIs. You get a detailed integration roadmap.
Phase 2: Build and test. Our engineers write the connectors, set up CI/CD, and deploy a staging environment for validation.
Every integration includes these deliverables by default.
No hidden surprises. Every project delivers the same production-ready package.
