Automate eBay and LeBonCoin Dropshipping

I run a growing dropshipping business on both eBay and LeBonCoin and I’ve reached the point where manual work is slowing everything down. I’m looking for a robust automation solution that covers the three pillars of my daily workflow—creating listings, processing orders, and syncing inventory—across the two marketplaces.

Here’s what I need the finished system to do:
• Pull product data from my suppliers (CSV, API or direct scrape) and publish new listings on eBay and LeBonCoin with the correct titles, descriptions, photos, prices and shipping terms.
• Push paid orders instantly to the relevant supplier, then return tracking details to the customer once the supplier dispatches.
• Keep stock levels and prices in sync on both marketplaces in near-real time to prevent overselling or out-of-date pricing.

eBay’s official REST API is available, while LeBonCoin may require creative handling (Selenium, Puppeteer, in-house API, or another reliable method). I’m flexible on the tech stack—Python, Node, PHP, or a low-code integration platform are all acceptable so long as the end result is stable, well-documented and easy for me to maintain.

Acceptance criteria
• One-click or scheduled listing upload to BOTH marketplaces.
• Automatic order routing and status updates.
• Inventory and price sync every X minutes (configurable), with logs or alerts on failures.
• Clear README or short video walkthrough so I can extend or troubleshoot the workflow on my own.

If you’ve built something similar or can demo a quick proof-of-concept, I’d love to see it.
