CDON Marketplace Connector: Sell your CS-Cart catalogue on CDON in Sweden, Denmark, Finland and Norway with prices per market, stock sync and order import1 of 7
What it does
CDON is a large Nordic online marketplace. In 2026 CDON moved sellers to a new merchant API and closed CDON Connect. This add-on integrates CS-Cart, CS-Cart Ultimate, Multi-Vendor and Multi-Vendor Ultimate with that new API, using your own CDON seller account. It suits shops in or outside the Nordics that want CDON as an extra sales channel, and marketplaces whose vendors sell on CDON with their own accounts.
How it works
Enter the merchant ID and API token from CDON, test in the sandbox, then switch to production. Tick your markets and exchange rates, map categories and properties, add products. The sync creates the articles, reads CDON's result per market and keeps stock and prices current. New CDON orders become CS-Cart orders; a shipment with a tracking number fulfils the CDON order. Failed jobs are retried and logged.

Bulk article creation (up to 100 per call) with per-article and per-market results; a create whose answer was lost is adopted on

Net CS-Cart prices (taxes that do not include tax) get the market VAT (SE 25 %, DK 25 %, FI 25.5 %, NO 25 %, editable).

Rate limits handled from the X-RateLimit headers; refused credentials pause the account.
Multi-Vendor: one marketplace account or one CDON account per vendor, vendor actions scoped to the own company.
Order and article links, connection and rules kept on uninstall (optional purge), restored on reinstall; Upgrade Synchronizer.
Tested on Multi-Vendor 4.17.2. First release.
Does it use the new CDON API?
Yes. It uses the CDON merchant API (merchants-api.cdon.com) that replaced CDON Connect, with the documented bulk article, status and order endpoints. Nothing of the closed CDON Connect API is used.
Do I need my own CDON account?
Yes. You sell with your own CDON seller account; the add-on uses your merchant ID and API token. CDON decides which markets your account may sell in.
Which editions and versions are supported?
CS-Cart, CS-Cart Ultimate, Multi-Vendor and Multi-Vendor Ultimate 4.17.2 to 4.21.x. In Multi-Vendor the marketplace owner can use one CDON account for everyone or let each vendor connect their own.
My store sells in EUR or USD. How are SEK, DKK and NOK prices made?
Per market: CS-Cart price x exchange rate (your own rate on the Rules page, or the rate of the currency in Administration > Currencies), then your markup and price ending in the market currency. CDON order amounts are converted back with the same rate.
Do I have to translate my products into Swedish, Danish, Finnish and Norwegian?
No. The add-on sends the languages your store has; CDON translates titles and descriptions that are missing in a market language.
Are returns imported?
No. The CDON merchant API has no return endpoints, so returns are handled in the CDON merchant portal. Cancellations are followed.
Where are my credentials stored?
In your own database, encrypted. They are never shown again after saving.
Does it send data to Kavio Labs?
No. The add-on talks to CDON only. The license check sends your domain name to the Kavio Labs license server once a day.
What happens when CDON is down or limits my calls?
Jobs wait and are retried automatically; on a rate limit the add-on waits until the window CDON names resets. Nothing is lost and nothing is sent twice.
What happens when the license expires?
Stock and price push and the import of new CDON orders stop until the license is valid; your links and settings are kept.
Add a released add-on to this order and save 15% on it. It uses the same edition and store domain.
