Manage Your eBay Store with ChatGPT and 3Dsellers
Add 3Dsellers to ChatGPT and sign in once. ChatGPT then works with every channel you sell on through 3Dsellers: eBay, Amazon, Walmart, Etsy, Shopify, WooCommerce, BigCommerce, TikTok Shop and more. Ask about your listings, orders and inventory in plain language, then let it create, update and publish them for you.

Run Your Marketplace Business from a ChatGPT Chat
On its own, ChatGPT can write a title or a description for you to paste into eBay. Connected to the 3Dsellers MCP server, it does the work: it creates products, fills in item specifics, publishes listings to eBay and your other channels, updates inventory and prices, and tags orders, all through your own 3Dsellers account. No API keys and no code.
To connect: in ChatGPT add a new app, paste the server URL https://api.3dsellers.com/mcp, choose OAuth, sign in with your 3Dsellers account and click Accept. Then pick 3Dsellers from the + menu in any chat.

Manage Your Entire Product Catalog from One Place
3Dsellers keeps all your products and listings from every selling channel in one catalog. With ChatGPT connected, you can search and update that catalog by asking. Find products by SKU or title, check where each one is listed, and make changes across channels from a single conversation instead of switching between marketplace dashboards.

Ask ChatGPT to take products from your eBay store and publish them to Amazon, Etsy, Walmart or Shopify through 3Dsellers. It can review product details, fill in missing fields and send the publish job, so you can grow into new channels without rebuilding every listing by hand.

Monitor and Sync Your Inventory in Real Time Across All Channels
Ask ChatGPT which products are low on stock, update the quantity on a listing or a variation, and let 3Dsellers sync the change to every connected channel. Daily inventory checks become a quick question, and overselling on eBay or Amazon becomes much less likely.
Synchronize Pricing Across All Your Selling Channels
Ask ChatGPT to compare prices across your listings, find products priced differently on different channels, and prepare price updates in 3Dsellers. You approve the changes, and 3Dsellers pushes them to every marketplace.

Enhance your Product Data with Custom Product Attributes
Ask ChatGPT which products are low on stock, update the quantity on a listing or a variation, and let 3Dsellers sync the change to every connected channel. Daily inventory checks become a quick question, and overselling on eBay or Amazon becomes much less likely.
Ask ChatGPT to review your listing titles, descriptions and item specifics, point out what is missing, and fill in product attributes in 3Dsellers. Complete product data helps your listings rank better on eBay and Amazon search and gives buyers the details they need.

Tailor Products to Each Selling Channel with Custom Channel Mapping
Each marketplace expects product data in its own format. ChatGPT can read the channel-specific fields exposed by 3Dsellers, suggest how your product attributes should map to each channel, and help you prepare the data before you publish, so your eBay, Amazon and Etsy listings all come out right.
Quickly Assign Products to Categories on Each Channel with the Smart Category Mapper
Ask ChatGPT to find products with unmapped categories, suggest the right eBay or Amazon category for each one, and set the category mapping in 3Dsellers. Correct categories make your products easier for buyers to find on every channel.

FAQ
Short answers to the questions sellers ask before they add 3Dsellers to ChatGPT.
Yes, once ChatGPT is connected to 3Dsellers. Ask it to create a listing, and it drafts the title, price, condition and item specifics, shows them to you, and publishes the listing to eBay through 3Dsellers after you approve. On its own, ChatGPT can only write text for you to paste.
In ChatGPT, add a new app, paste https://api.3dsellers.com/mcp as the server URL, choose OAuth, sign in with your 3Dsellers account and click Accept. Then pick 3Dsellers from the + menu in any chat. It takes about two minutes.
Not yet. You add 3Dsellers to ChatGPT yourself as a custom app with the server URL above. It takes two minutes and works the same way as a directory app once it is connected.
Search and create products, publish listings to eBay and your other channels, fix item specifics in bulk, update inventory and prices, find and tag orders, run CSV imports and reply to buyers in your Helpdesk. The full list of more than 150 tools is on the 3Dsellers MCP page.
ChatGPT never sees your eBay password. It connects to 3Dsellers with OAuth, can only use the tools listed on the 3Dsellers MCP page, and asks for your approval before it runs a tool that changes data. You can disconnect it from the assistant or from 3Dsellers Settings at any time.
No. The connection is included in every 3Dsellers plan, including the free trial. Actions the AI runs use AI actions that you buy in advance in the AI Lite, AI Pro or AI Elite package. Reading your data is free.
