The Trendyol Marketplace Connector bridges your Shopify store and Trendyol, Turkey's largest e-commerce marketplace, so you list once and sell on both without manual re-keying. This is a build-to-order integration: ECOSIRE configures it for your catalog structure, locations and tax setup, installs it on your store, and supports it after launch. It is not an instant App Store download — you buy the build, we deliver and install it.

On the Shopify side, the connector reads your products through the Admin GraphQL API, maps Shopify products, variants, options and metafields to Trendyol's required attributes, and pushes listings into the Trendyol Marketplace Seller API. We map your Shopify multi-location inventory to the warehouse Trendyol fulfils from, so stock stays accurate across channels.

Catalog and category mapping handles Trendyol's strict category attribute model — brand, color, size and mandatory fields — with bulk listing creation for large catalogs. Inventory and price sync runs on a schedule and reacts to Shopify inventory_levels/update and products/update webhooks, so a sale on either side adjusts the other. Order import pulls Trendyol orders into Shopify as native orders for unified fulfilment, and shipment sync pushes tracking and carrier data back to Trendyol when you fulfil. A commission and payout view surfaces Trendyol's deductions so your true margin is visible.

Authentication uses your Trendyol Seller API key, secret and supplier ID stored securely server-side; Shopify access uses a scoped custom app with OAuth. Everything is built to your real data — we don't ship a generic black box. After delivery you get documentation, a walkthrough, and ongoing support for marketplace API changes.
