Bulk Upload Magento Products to Amazon

I have between 100 and 500 physical products currently sitting in my Magento 2 store that now need to be live on my Amazon Seller Central account. All core data—titles, SKUs, prices, images and inventory—already exists inside Magento, but I’ll need your help transferring it smoothly and making sure each listing is fully retail-ready on Amazon.

Here is the scope:

• Export the catalog from Magento 2, clean up any data that Amazon rejects, then import or upload through the most efficient route (flat-file bulk templates, M2E Pro, or direct API—whichever you prefer so long as it works).
• I have categories outlined for most items, yet some products need the correct Amazon node chosen. Please step in only where categories are missing or inaccurate.
• Map all required attributes (brand, bullet points, variations, images, compliance fields) so every listing goes active without suppression warnings.
• Provide a final report of ASINs created or attached, plus a CSV or Excel file of the data you submitted for my records.

Acceptance is simple: every assigned SKU shows “Active” in Seller Central, matches my Magento data, and any listings created from scratch carry the right category node.

If you’ve handled Magento-to-Amazon migrations before, this should be straightforward; please share a quick note on your workflow so we can get started immediately.
