N11 Marketplace Connector: Create products, sync stock and price and import orders and returns from your own N11 seller account1 of 7
What it does
N11 is an online marketplace in Turkey. If you run a CS-Cart or Multi-Vendor store and want N11 as an extra sales channel, this add-on connects your seller account to your shop with the API key pair N11 gives you. Each vendor of a marketplace can connect an own seller account, or the owner can use one account for all. N11 has no test environment, so test mode only reads data.
How it works
Enter your API key, API secret, integrator name and shipment template, then test the connection. Map categories and attributes, set markup and stock buffer. The sync creates products as N11 tasks, reads the result per product and sends stock and price. Packages are imported, their lines are approved, returns are listed and can be approved, and failed jobs retry by themselves and stay visible in the log.

Multi-Vendor: marketplace owner mode or one N11 account per vendor.
Tested on Multi-Vendor 4.17.2. First release.
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 N11 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 N11 only. The license check sends your domain name to the Kavio Labs license server once a day (Kavio Labs downloads).
Is there a test environment at N11?
No. N11 publishes no sandbox, so "test mode" uses the same API as live mode. Test your first products with a few items of your own.
Does it need a webhook?
No. N11 offers none for sellers; the add-on polls N11 on every sync interval, so no inbound address has to be opened.
Why can't I send my own tracking number?
The N11 seller API has no call for it. N11 assigns the cargo from your shipment template and returns the tracking number with the package; the add-on reads it back.
What happens when N11 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 syncs or order steps). Work already under way is still finished.
How do I get updates?
Install the new package over the old one. See Installation.
