Pazaryeri Sync for Trendyol sends your WooCommerce stock levels (and, optionally, prices) to your approved Trendyol listings through the official Trendyol Seller Integration API, so an item that sold out in one channel stops selling in the other.

Stock sync for simple products and variations, matched by barcode (Trendyol barcode field, SKU or GTIN)
Optional price sync (regular and sale price) with a price multiplier for marketplace markup
Every 15 minutes, hourly, twice daily or daily schedule plus a “Sync now” button
Reads Trendyol’s batch results and shows item-level errors on the Logs screen
Stage (test) environment support
HPOS compatible

A separate Pro add-on adds product upload, order import and returns. This free plugin works fully on its own and contains no locked features.

External services

This plugin relies on Trendyol, a third-party marketplace service operated by DSM Grup Danışmanlık İletişim ve Satış Ticaret A.Ş. It is not affiliated with or endorsed by Trendyol.

What it connects to: the Trendyol Seller Integration API at https://apigw.trendyol.com (or https://stageapigw.trendyol.com when stage mode is on).
What is sent: your Trendyol seller ID and API credentials (as HTTP authentication), product barcodes, stock quantities and, if you turn on price sync, product prices. The plugin also reads the batch results for those requests.
When: only after you enter your own Trendyol API credentials, on the schedule you choose (every 15 minutes, hourly, twice daily or daily) and when you click “Sync now”. No data is sent before the plugin is configured.
