Trendyol and Hepsiburada integration: managing stock, prices and orders in one place

Short answer: Trendyol and Hepsiburada offer seller APIs that exchange product, stock, price and order data automatically. With them you can run your own site, your accounting software and the marketplaces from a single stock and order hub.

What happens without integration?

When the same product sells on your site and two marketplaces, a sale in one place means manually lowering stock everywhere else. On busy days that delay leads to selling items you no longer have, cancellations and a lower store rating. Price changes and campaigns also have to be done channel by channel.

What marketplace integration covers

Product upload: bulk listing with category and attribute mapping.
Stock and price sync: automatic updates to every channel from one stock source.
Order import: marketplace orders land in your system and their status stays in sync.
Shipping and invoicing: shipping labels and invoices created with the order.

Off-the-shelf integrator or custom integration?

Subscription-based integrator tools are a good start for standard needs. A custom integration makes sense when your product structure, accounting software or warehouse process is non-standard, when variants or multiple warehouses get complicated, or when you want all data to stay in your own system.

Common mistakes

Mapping attributes (color, size, brand) incorrectly to marketplace categories, so products don't list or show up under the wrong filters. Syncing stock too rarely, so a sold item sells again elsewhere. Ignoring API rate limits, so updates stall at peak hours. And not reflecting returns and cancellations back into stock, so counts drift from reality over time.

Where to start

Pick a single source of truth for stock (your site, ERP or accounting software). Clean your product data: barcodes, SKUs and attributes must be consistent. Test with a small set of products before rolling out to the whole catalog.
