Extensibility Without Limits
As your business evolves and new needs arise, our custom connectors can adapt and expand effortlessly.
How our custom API integration works?
Take BigCommerce, for example. While its backend is intentionally closed to
direct custom coding, our approach is different.
1. We built a secure ‘connector app’ that acts as an intermediary. Bridging two apps through plug-ins.
2. This connector can communicate with your BigCommerce store and your other backend systems.
3. We can apply your specific business rules, format data exactly as needed.
Experience with major platforms.
We can apply the same flexible connector approach to Shopify, ERP systems, CRMs, marketing automation tools – virtually any platform with data to share.

“
Fonseka didn’t just integrate our systems — they fundamentally improved how our business operates. We had multiple platforms that technically ‘worked’, but nothing talked to each other properly. The Fonseka team took the time to understand our workflows, designed a custom integration layer, and delivered something that actually reduced admin and errors across the board.The result was faster turnaround times, cleaner data, and far less manual intervention. They feel more like a long-term technical partner than a vendor.

This was the difference between a workaround and a scalable solution. We were hitting limits with off-the-shelf tools and patchy integrations. Fonseka designed and built a custom API solution that connected everything cleanly and reliably — and future-proofed us for growth.What stood out was their ability to explain complex technical decisions in plain language, while still executing at a very high technical standard. It gave us confidence at every stage.
