Marketplace Integration — Managing Trendyol, Hepsiburada and Amazon from One Panel

July 6, 2026 · 2 min read

A business doing e-commerce in Turkey sooner or later starts selling on more than one channel: Trendyol, Hepsiburada, Amazon, maybe N11 — and of course its own site. That's exactly where the trouble starts: five separate panels, five separate stocks, five separate order lists. Marketplace integration collapses that chaos into one screen.

What is marketplace integration?

Marketplace integration connects your e-commerce infrastructure to the marketplaces' systems via an API. Once connected, products, stock, prices and orders synchronize by themselves across channels.

What does it synchronize?

  • Stock: When an item sells on your site, its Trendyol stock drops instantly — and vice versa.
  • Prices: You change the price in one place; per-channel price/commission rules can be defined.
  • Orders: Orders from all channels flow into one list; the shipping process is triggered from there automatically.
  • Product listing: You enter a new product once and push it to the marketplaces you choose in bulk.
  • Invoicing: Order data is passed to the accounting/ERP side and the e-invoice is issued automatically.

Why is it so critical?

The most expensive mistake is overselling: you sell the last unit on your site and on Trendyol in the same minute, and you're forced to cancel one. On marketplaces a cancellation lowers your seller score — and a store with a lower score loses visibility, and therefore sales. Every store updating stock by hand eventually lives through this loop.

The second gain is time: processing 50 orders a day across five panels one by one consumes someone's entire day. With integration the same work takes minutes.

Your own site or the marketplace?

They're not rivals — they're stages. A marketplace hands you ready customer traffic but takes commission, and the customer belongs to the platform, not to you. Your own e-commerce site means commission-free sales and a customer base of your own. The healthy setup is usually this: be visible on the marketplace, move the customers you win to your own site — and integration unites the two in a single operation.
