About this Product

The Trendyol Marketplace Connector for Shopify lets you sell into Trendyol's 30M+ buyer base without leaving Shopify as your source of truth. ECOSIRE custom-builds, installs and configures this connector for your store — it is not an instant App Store download. After purchase we scope your catalog, map your categories, connect your Trendyol Marketplace API credentials, and hand you a working, tested integration.

On the Shopify side the connector reads your products via the Admin GraphQL API, respects multi-location inventory, and stores Trendyol-specific data (barcode, Trendyol category ID, attribute set, cargo company) in Shopify metafields so nothing pollutes your core product data. Webhooks on orders/create, inventory_levels/update and products/update keep both systems current in near-real time, with a scheduled reconciliation pass as a safety net.

Core capabilities: bulk product listing to Trendyol with Turkish category and attribute mapping; two-way inventory and price sync (stock decremented on either platform reflects on the other); order import with line items, customer address and cargo tracking numbers written back to Shopify fulfillments; and commission- and VAT-aware pricing so your Trendyol list price accounts for marketplace commission and Turkish KDV before it ever goes live.

Because every store's catalog, tax setup and fulfillment flow differ, we treat this as a build-to-order engagement. You get a connector tailored to your category tree and operating model, deployed to your store, plus documentation and a support window. Honest delivery: typical build and go-live is 2–3 weeks after we receive your Trendyol API access and a catalog sample.

What you get

A fully configured Trendyol connector installed on your live Shopify store and connected to your Trendyol seller account

Catalog onboarding: your existing Shopify products mapped to Trendyol categories and attributes, bulk-published and verified

Trendyol Marketplace API credentials wired in securely (supplier ID, API key/secret) with no secrets stored in plaintext

Commission- and VAT-aware pricing rules configured to your margin and KDV requirements

Webhook + scheduled-sync setup with monitoring so inventory and orders stay aligned automatically

Admin documentation, a short walkthrough session, and a defined post-launch support window for fixes and questions

Frequently Asked Questions about Trendyol Marketplace Connector for Shopify

Is this an instant download from the Shopify App Store?

No. This is a build-to-order engagement. ECOSIRE custom-builds the connector around your catalog, category tree and tax setup, then installs and configures it on your store. There is no self-serve App Store install — we deliver and test a working integration for you.

How long until it's live after I purchase?

Typical build and go-live is 2-3 weeks from the point we receive your Trendyol Marketplace API access (supplier ID and API credentials) and a representative sample of your catalog. Larger or unusual catalogs can take longer, and we'll confirm a concrete timeline during scoping.

What do you need from me to get started?

Your Trendyol seller/supplier account with Marketplace API access enabled, Shopify Admin access (or a collaborator invite with the right scopes), and confirmation of your pricing, commission and KDV/VAT rules so list prices are calculated correctly.

How does inventory stay accurate across both platforms?

The connector uses Shopify webhooks and the Admin GraphQL API for near-real-time updates, respecting multi-location inventory, plus a scheduled reconciliation pass that catches any missed events. Stock sold on either Trendyol or Shopify is reflected on the other to reduce overselling.

What about ongoing support and updates when Trendyol's API changes?

Every build includes a defined post-launch support window for fixes and questions. Because Trendyol periodically changes its Marketplace API and required attributes, we also offer ongoing maintenance so the connector keeps working as the platform evolves — we'll quote this based on your catalog size and channel volume.
