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.

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
  • Credentials stored encrypted, 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 N11 category tree, with a markup and a brand per category
  • Price rules: markup percent and fixed amount, price endings, exchange rate
  • Stock buffer, minimum and maximum
  • Products created as N11 tasks, with the status and the reason per product and a retry in one click
  • Order import from shipment packages with buyer, addresses, company and tax number, prices as sold, status mapping
  • Order lines approved at N11 (picking) and the cargo tracking number read back
  • Returns listed and approvable, partial cancellation of approved order lines
  • No webhook to open: the add-on polls and retries failed imports hourly
