ERLI Connector for OpenCart — products, prices, stock and orders for the ERLI marketplace

CatCode ERLI Connector sends products from OpenCart to the Polish ERLI marketplace: name, description, photos, price and stock, and updates a changed price and stock on their own. In Pro, ERLI orders arrive in OpenCart and statuses and tracking go back. Among ERLI integrators we found BaseLinker, Sellasist, Apilo and a PrestaShop module; there is no OpenCart connector.

Checked on an ERLI mock. We have no ERLI key or sandbox (the sandbox is issued by ERLI support), so no request has reached the real ERLI.

Products

On the ERLI tab of a product you switch selling on and may set an own price. There are the buttons Send now and Read from ERLI. The free version keeps up to 10 products. A changed price and stock go as a separate request; zero stock takes the offer down; a product without a photo is refused with a plain message.

Orders (Pro)

Paid ERLI orders are imported into OpenCart with lines, delivery, VAT and invoice data; importing again creates no duplicate; a cancellation on ERLI cancels the order, and the Shipped status in OpenCart goes back to ERLI.

How it works, step by step

1. Create an API key in the ERLI panel.
2. Enter the key and test the connection.
3. Switch selling on ERLI on for products.
4. Run Send the queue.

Under the hood

• The key is encrypted and never put in a page.
• A send queue with retries as ERLI asks (429, 5xx).
• Languages: English, Polish.

How to install

1. Extensions → Installer: upload the zip.
2. Extensions → Modules: install and open the module.
3. Module settings: the ERLI API key (seller panel → own integration by API).
4. Try one test order.

OpenCart 4.0.2 or newer is required. Do not rename the archive.
