Hepsiburada & n11 for OpenCart 2.3, 3.x and 4.x — prices, stock and orders

Hepsiburada & n11 Connector for OpenCart links your existing Hepsiburada and n11 listings with the shop products by stock code, options included, and from then on sends the price and stock there itself. Pro brings the orders of both marketplaces into OpenCart and sends packing, approval, cancellation and the invoice link back.

What the buyer sees

A buyer on Hepsiburada or n11 sees the price your rules make (with or without KDV, the rate to lira, a markup, rounding to ,90) and the real stock level. A disabled product gets stock 0 on the marketplace.

What the admin gets

Extensions → Modules → Hepsiburada & n11 Connector: each marketplace is switched on separately, with a connection check, separate price rules for Hepsiburada and n11, a table of linked products and a 30-day API log.

In Pro the order page gets a marketplace panel: the package number, tracking, a “Read again” button and the invoice link. Packing, n11 approval and line cancellation run from a button or from an OpenCart order status.

How it works, step by step

1. You switch on the marketplace you need, enter the credentials and check the connection.
2. The import reads the listings and links them with products by stock code (for n11 also by barcode), option codes included.
3. Price or stock changes join a queue; cron sends them every minute, and every hour the module compares everything.
4. The result for every code shows in the product and in the log.
5. In Pro orders come in by polling (and by the Hepsiburada webhook once Hepsiburada switches it on), and actions from the shop go back.

Under the hood

• Keys are stored encrypted (AES-256 with HMAC).
• Hepsiburada gets up to 1000 codes per request with at most 5 open uploads, n11 up to 500.
• Only changes are sent; a disabled product gets 0 only where a listing really exists.
• Orders are never doubled: a lock and a unique marketplace + number key.
• Address: il, ilçe and mahalle go to the zone, city and second address line; VKN, tax office and TCKN go to the order.
• Cancelling from the shop is off by default for Hepsiburada because of its fines.

How to install

1. Extensions → Installer: upload the archive for your version without renaming the file.
2. OpenCart 2.3: the installer copies files only over FTP; without FTP copy the contents of upload/ to the shop root.
3. OpenCart 3.x and 2.3: Extensions → Modifications → Refresh.
4. Extensions → Modules → Hepsiburada & n11 Connector → install → edit.
5. Enter the credentials, check the connection, set the price rules and run the listing import.
6. For Pro: paste the key or start the 7-day trial on the Licence tab.
