Key points

What the free version does

You paste the ERLI API key (live or sandbox environment) and Check the connection shows the shop name.

What Pro adds

ERLI orders from the ERLI inbox become WooCommerce orders: a PLN total, lines, delivery address, pickup point and NIP; a second fetch makes no duplicate, the message is marked read and an unreachable ERLI loses no order.

How much it costs

The base version is free. Pro costs 1490 UAH for a one-year licence. A year of updates, technical support and all Pro features.

The trial starts when you ask

A fresh install is the free version, nothing switches on by itself. The “Try Pro for 7 days” button → e-mail → the key right in the window and by e-mail.

One key — a site and a staging copy

Moving the site? Unlink the licence on the old domain and activate it on the new one yourself. A staging copy (staging., dev.) works with the same key and does not take a site slot. For studios — keys for 5 or 25 sites, or unlimited.

Technical requirements

  • WordPress 6.2+, WooCommerce 7.0+, PHP 7.4+.
  • An ERLI seller account with shop API access.

Full module description

CatCode ERLI Connector for WooCommerce links a WooCommerce shop to the Polish marketplace ERLI through its shop API: it links ERLI products to yours by externalId or SKU, sends stock and prices and, in Pro, also brings ERLI orders into WooCommerce. ERLI offers no WooCommerce connector (we looked through its documentation and a search on 2 November 2026).

This module has never run against the real ERLI. We had no ERLI key (the sandbox is issued by ERLI support), so nothing was ever sent to ERLI.

What the free version does

You paste the ERLI API key (live or sandbox environment) and Check the connection shows the shop name. Link products from ERLI reads the ERLI products and links them to yours by externalId, then by SKU; ERLI products without a match are listed and nothing is created or deleted. Stock and prices (in grosze) go in batches; a repeat run with no change sends no extra requests. An unreachable ERLI or a 429 gives a plain message and the change arrives after it recovers. The key is stored encrypted and never printed back.

What Pro adds

ERLI orders from the ERLI inbox become WooCommerce orders: a PLN total, lines, delivery address, pickup point and NIP; a second fetch makes no duplicate, the message is marked read and an unreachable ERLI loses no order. The order status you choose (we checked Completed) is pushed to ERLI. Pro also has a tab for publishing new products to ERLI, but the publishing itself, tracking numbers and the import of one order by number were not run.

How it works, step by step

  1. In the ERLI seller panel choose Own integration via API and generate a key for the shop.
  2. Paste it in WooCommerce → ERLI → Connection and check the connection.
  3. On the Listings tab press Link products from ERLI.
  4. Change a price or stock in WooCommerce and see it arrive at ERLI.

Under the hood

  • We work out the difference from the last send, so only changed products go to ERLI; changes go every 5 minutes through WP-Cron.
  • The API log is kept for 30 days and the key never reaches it.
  • HPOS compatible; languages: English, Polish.

How to install

  1. Plugins → Add New → Upload Plugin: choose the zip and activate it.
  2. WooCommerce → ERLI: paste the API key.
  3. Enter the service credentials and test the connection.
  4. Try one test order before you switch the automation on.

The module is not on wordpress.org yet: the free version and Pro are one archive from this page. Without a key it works as the free version.

Is this an official ERLI plugin?

No. ERLI offers no WooCommerce connector; we made the module and the trademark belongs to ERLI.
