With so many businesses relying on multiple platforms like CRMs, ERPs, eCommerce systems, and cloud-based apps API integration services have become crucial for keeping everything connected. But managing communication between these systems can be complex, especially when each platform has its own protocols, data formats, and authentication methods. I'm interested in how modern API integration services are handling these multi-platform connections efficiently. Are they using middleware, iPaaS (Integration Platform as a Service), or building custom connectors from scratch? What are the common challenges in maintaining data consistency, performance, and real-time sync across various systems? If you’ve had experience working with API integrations in a multi-platform environment, I’d love to hear how you approached it and what worked.
