The Trendyol Connector for Business Central is a build-to-order AL extension that turns your Trendyol seller account into a fully integrated sales channel inside Microsoft Dynamics 365 Business Central. ECOSIRE builds it to your catalog, installs it as a per-tenant extension on your BC environment (cloud SaaS or on-prem), and supports it after go-live.

This is not an instant AppSource download. We scope your Trendyol category tree, warehouse setup, tax treatment and fulfillment model, then deliver a connector tailored to how your business actually runs.

How it works. The extension authenticates to the Trendyol Marketplace REST API (Seller/Integration API) using your supplier ID and API credentials. A Job Queue entry polls Trendyol on a schedule you control — pulling new orders and writing them into BC as Sales Orders (or Sales Invoices) with customer, line, discount and shipping mapping. Product and inventory flow the other way: BC item availability and prices publish to your Trendyol listings, with a category and attribute mapping layer so each item lands in the correct Trendyol category. Shipment confirmation and tracking numbers write back to Trendyol when you post a warehouse shipment, and returns/cancellations are pulled in and matched to the originating order.

Built natively in AL. We use table and page extensions, event subscribers (no base-app modification), dedicated setup pages, a permission set for least-privilege access, and structured error logging so failed syncs are visible and replayable. Optional Dataverse / Power Platform surfacing is available if you want Trendyol order signals in Power BI or a Power App.

You get a connector that fits your Trendyol operation in Turkey and the wider MENA region — owned by you, maintained by us.
