Trendyol Marketplace Connector: Create products, sync stock and price and import orders and returns from your own Trendyol supplier account1 of 9
What it does
Trendyol is a large online marketplace in Turkey. If you run a CS-Cart or Multi-Vendor store and want Trendyol as an extra sales channel, this add-on connects your seller account to your shop. Each vendor of a marketplace can connect an own supplier account, or the owner can use one account for all.
How it works
Enter your supplier ID, API key and API secret, test the connection and register the webhook. Map categories and attributes, set markup and stock buffer. The sync creates products, reads the result per product and pushes stock and price. Orders, status changes and returns are imported; picking and own-carrier tracking are reported back. Failed jobs retry by themselves and stay visible in the log.
Features
Credentials stored encrypted, separate test and live mode, one-click connection test
Job queue with automatic retries and a log with filters and CSV export
Works with cron (command line or secret address), no long requests during checkout
Multi-Vendor: one marketplace account or one account per vendor
Category and attribute mapping from the Trendyol category tree, with a markup and a brand per category
Product creation with the batch result and the reason per product, retry in one click
Order import with buyer, delivery and invoice address, company and tax number, prices as sold, status mapping
Picking, invoice number and own-carrier tracking reported to Trendyol
Returns imported and approvable, cancellation of a package
Webhook registration and hourly retry of failed imports

Requirements
Platform
CS-Cart and Multi-Vendor 4.17.2 or later (4.21.x supported)
Requirement
Administrator access to the store's admin panel
Requirement
A Trendyol seller account with API access: the supplier ID, API key and API secret from the seller panel (Hesap Bilgilerim / My Account, "Entegrasyon Bilgileri"; only the master user sees it)
Requirement
Products with images that are reachable from the internet (Trendyol downloads them)
Requirement
A cron job on your server (see step 6)
Requirement
Optional, for test mode: the Trendyol stage environment. Trendyol allows stage access only for allow-listed server IP addresses and a test seller account; you request both from Trendyol (see "Test mode" below).

Does it work with CS-Cart and Multi-Vendor?
Yes. The add-on supports CS-Cart and Multi-Vendor. In Multi-Vendor the marketplace owner can use one Trendyol account for everyone or let each vendor connect their own.
Which CS-Cart versions are supported?
4.17.2 to 4.21.x.
Where are my credentials stored?
In your own database, encrypted. The key is derived from your store's secret in config.php, so a database dump alone does not reveal them. They are never shown again after saving.
Does it send data to Kavio Labs?
No. The add-on talks to Trendyol only. The license check sends your domain name to the Kavio Labs license server once a day (Kavio Labs downloads).
What happens when Trendyol is down?
Jobs fail, wait and are retried automatically (5 minutes up to 12 hours). Nothing is lost and nothing is sent twice.
What happens when the license expires?
New work stops (no new documents, rates, syncs or payments). Work already under way is still finished.
How do I get updates?
Install the new package over the old one. See Installation.
Multichannel Product FeedsProduct feeds for Meta, TikTok, Pinterest, Microsoft Shopping, Snapchat, Criteo and idealo, validated before the channel sees them.
