Publishing products to channels in 3Dsellers allows you to create listings on your connected marketplaces (eBay, Amazon, Walmart, etc.) directly from your Product Catalog.

You can publish products individually or in bulk, configure listing settings, apply mapping templates, and set up policies for each publication. Once published, products become live listings on the selected channels, and you can manage them centrally from your catalog.

So after creating products in your catalog, the next step is publishing them to your connected marketplaces.

You can publish individually or in bulk.

The "up to quantity" setting means that we will send a specific quantity value to the channel based on your product inventory. If your inventory exceeds the set value, we will send the set value.

If it falls below, we will send the actual quantity. For example, if you have 4 units in stock and set the maximum quantity to 2, 3Dsellers will display 2 as your product quantity on the channel.

You can customize the SKU code for a specific selling channel by using a product attribute – either a product property or a custom attribute. This allows you to list and publish the product on the chosen channel with a custom SKU.
