What it does
modified eCommerce is a self-hosted shop system with a free core download and separately available extensions and templates. The maintained project provides store administration and public source code under GPL version 2.
A stock connector needs access to the right shop data. The official modified eCommerce API covers catalog, customer and order resources, with permissions assigned per account and endpoint. In the backend, open Customers > API Access and enable the intended account. The interactive reference at /api/v1/docs/ uses Authorize with that account's email and password.
This connection requires modified 3.2.0 or later and PHP 8.2 or later. Check those requirements separately from the core shop's hosting requirements.
For the storefront itself, download the stable package, create a MySQL database, upload the shoproot contents and follow the web installer. Then sign in to the administration area to configure categories, items and the shop settings. The current stable download is 3.3.0.
The core is free to download and use under GPL version 2. Hosting, premium templates and separately sold modules remain outside that free software offer.
