Senior API Integration Development PartnerIntegration Partner
We build and maintain API integrations that connect your tools and data. Fixed pricing, 8-12 week delivery, full code ownership.
IRPR builds custom API integrations for SaaS platforms, legacy systems, and third-party services. We use Node.js, Python, and cloud-native middleware to connect systems via REST, GraphQL, and SOAP endpoints.
Projects average 8-12 weeks and cost $80K to $250K. Every integration includes automated testing, rate limiting, and error handling. We support HIPAA, PCI-DSS, and SOC 2 compliance.
We are hired by CTOs whose legacy CRM won't talk to their ERP, by product managers who need to merge data from four sales tools into one dashboard, by compliance officers who need secure API gateways, and by founders who want to launch a new product integrated with Stripe and Shopify.
Types of software we ship.
Custom API Gateway
Build a centralized gateway that routes, throttles, and authenticates API traffic across microservices. Uses Kong or Express Gateway.
Data Sync Engine
Two-way sync between Salesforce and your internal database. Handles conflict resolution, incremental updates, and scheduled jobs.

API Integration Development That Ships on Time
We deliver complete, tested API integrations in 8-12 weeks.
Every integration starts with a two-week Roadmap phase where we map endpoints, authentication flows, and data models. You get a fixed price and timeline before development begins.
Our senior engineers build the integration with automated tests, rate limiting, and error logging. We deploy to staging first, then production with a full rollback plan.
How We Compare to Generic Development Shops
The difference between working with IRPR and hiring a freelance developer.
Generic shops treat API integration as a side task. They start without a clear plan, change scope without notice, and hand over undocumented code.
IRPR treats every integration as a standalone product with a defined scope, fixed price, and professional documentation.
