This is for shop owners. You need a SellerSideKick shop on a monthly plan (such as Pro or Pro Plus) and an AI assistant that can use connectors: Claude, ChatGPT or Gemini.
1. Prepare the sheet#
One row per product, matched by SKU (your own product code). Use the columns you need:
| Column | Example | Notes |
|---|---|---|
| SKU | TM-001 | Required on every row. |
| Name | รถเหล็กโทมิก้า รุ่นรถตำรวจ | Thai, English or both. |
| Price | 139 | In THB. |
| Stock | 40 | Units on the shelf now. |
| Category | Toys | Must be one of your shop's categories. |
| Brand | Tomica | A new brand is added for you. |
| Parent SKU | SHIRT-01 | Only for a variant (a size or colour of another product). |
Any layout works; the assistant maps your columns. Keep one SKU per row.
2. Connect your assistant#
Add the SellerSideKick connector at https://mcp.sellersidekick.ai/mcp, sign in with your SellerSideKick account, pick the shop and tick the permissions:
catalog:read, reading your shop, categories, products and promotions, is always on.catalog:writefor prices, product details and new products.stock:writefor stock counts.promotions:writeonly if you want the assistant to change promotions.
Step-by-step for each assistant: Connect ChatGPT, Claude or Gemini.
3. Give it the sheet#
Attach the file and say what you want. For example:
Here is my price list. Update the prices in my SellerSideKick shop. Show me the preview first and wait for my OK.
This is today's stock count. Set the stock in SellerSideKick to these numbers. Preview first.
Add the new products in this sheet. The "Size" column makes variants of the main product.
4. Check the preview#
The assistant runs a dry run first: nothing changes yet. It should tell you which shop it is working on and show:
- how many rows would be created, updated or left unchanged;
- every row with an error and why, for example an unknown category or a SKU that exists only on a marketplace.
Fix the sheet or tell the assistant how to handle the error rows. When the preview looks right, say yes.
5. Apply and check#
The assistant sends the same rows for real and reports the result. Open the dashboard at app.sellersidekick.ai to see the changes. Every change made through the connector is listed with its before and after values in Settings → API keys.
What happens on the marketplaces#
- Stock reaches your linked Shopee, Lazada and TikTok listings, usually within about 10 minutes.
- Prices and product details change your SellerSideKick store and chat bot only. Change marketplace prices in each marketplace's seller center.
If something goes wrong#
- "Not on a monthly plan": the connector works on Pro and Pro Plus. See current plans in the app.
- A row says the SKU is not on your SellerSideKick store: the product exists only on a marketplace. Add it to your store from the dashboard first.
- "Missing permission": reconnect and tick the permission the assistant asked for.
- More: Errors and limits.
