Time to start: As soon as possible

Project description:
"I maintain two absolutely identical PrestaShop stores—Store A is the master, Store B lives on a different domain. I’ve already added new categories, suppliers, manufacturers, products, images, attributes and features to Store A, and I don’t want to enter them twice.

What I need is a lightweight module that talks to the PrestaShop Webservice API and, once a week, pulls only the data that is missing or has changed since the last run. The priority elements are categories & products, suppliers & manufacturers and stock numbers, plus everything that makes a product complete—images, combinations, features, etc. IDs must remain untouched so both databases stay consistent.

There is one twist: when Store B records a sale, the corresponding stock has to be immediately (or near-immediately) deducted in Store A. I’m open to the best technical approach—webhooks, queued jobs, or an API push—so long as it’s reliable and doesn’t overload either shop.

Key things I’m expecting from you:
• An installable PrestaShop module (or paired modules if needed) that handles the weekly pull from Store A to Store B and the stock push in the opposite direction.
• A simple configuration screen where I can set API keys, choose the sync frequency (weekly by default, manual trigger optional) and enable/disable specific data groups if required.
• Clear installation and usage notes so I can redeploy it on staging or future clones without assistance.
• A brief test report or demo showing that new categories, products and their related entities appear in Store B and that a test order in Store B reduces stock in Store A.

If you’ve built similar cross-store connectors, please mention any reference modules or methods you plan to leverage. I’m ready to start as soon as we agree on the technical outline and timeline." (client-provided description)
