How We Integrate eBay With Your Store
eBay is one of the few marketplaces that gives sellers genuinely mature, well-documented REST APIs. The Sell suite — Inventory, Fulfillment, Marketing and Account APIs — lets you create listings, manage orders, sync stock and run promotions programmatically instead of clicking through Seller Hub. AppsyOne builds custom integrations on these official Sell APIs and plugs eBay straight into your appsy.one store, so your catalogue, prices and inventory flow both ways automatically rather than being re-keyed by hand.
For Indian sellers, eBay is above all a cross-border channel: list once and reach buyers across the US, UK, Europe and beyond. That means multi-currency pricing, export-ready shipping and item specifics that match each site's requirements. We handle the Inventory API's offer-and-SKU model so a single product in your store maps cleanly to eBay listings, and we pull orders back through the Fulfillment API with tracking pushed on dispatch — the whole loop wired to how your business actually operates.
Cross-border buyers judge you on feedback before they ever click Buy, so accurate item specifics, honest handling times and clean tracking aren't optional — they protect the rating that wins international sales. We build that discipline into a pipeline you pay for once, as a flat fee, with no cut of your payouts. Multi-currency proceeds from the US, UK and EU settle back and reconcile to your accounts, and eBay runs from the same catalogue as your store, ERP and shipping.

eBay Custom Integration vs a SaaS Aggregator
When a plug-and-play tool is the smart call — and when a custom build you own pays off.

We build the complete application — integrations included
Most clients need more than a connector. We build the full product — your storefront, seller portal, admin dashboard, mobile app or internal ERP — and wire the marketplace integrations into it as part of the same build. One team, one codebase, one point of accountability.
- Custom web & mobile applications
- Seller / vendor portals & dashboards
- ERP, CRM, Tally & accounting bridges
- Warehouse, inventory & order management
- Payment, logistics & shipping APIs
- Workflow automation and AI features
Full custom builds are scoped and quoted to your requirement — not packaged into the plans above.
