Catalog Channel Template Mapping in 3Dsellers allows you to control how product data from your Product Catalog is mapped to the fields required by each selling channel.

Each marketplace requires specific information such as:

Mapping templates automatically take the data from your catalog product properties and send it to the correct listing fields on the selected channel.

This allows you to publish many products quickly while ensuring that listings meet the requirements of each marketplace.
​

You manage mapping templates at: Attribute Mapping Templates page.

When you enable the Product Catalog for a channel and import products, 3Dsellers automatically creates a default mapping template for that channel.
​

This default template already includes common mappings such as:

The default template allows you to start publishing products immediately without configuring every field manually.

You can update the template at any time to:

You can create multiple templates for the same channel depending on your listing strategy.

For example:

Templates are selected when publishing products to a channel, allowing you to control how product data is mapped for each listing.

Listing policies such as:

are not configured inside the mapping template.

Instead, policies are selected when publishing products to a channel together with the mapping template.

Mapping templates define how your catalog product data is transformed and sent to a selling channel.

Each template is associated with:

The marketplace or selling account where the listing will be published.

Example:

Some channels support different listing formats.

For example, eBay templates may be created for:

Different listing types may include different required fields such as starting price or duration.

To access mapping templates:

This opens the Attribute Mapping page where you can:

The mapping template interface is divided into two main areas.

The left panel contains all the mapping sections available for the selected channel.

These sections organize fields into logical groups such as:

The available sections depend on the selected channel.

For example, eBay templates include an eBay Categories section where you can view and map category-specific attributes.

The right panel shows the fields for the selected section.

For each field you will see:

This is where you configure how data from the catalog is used to populate listing fields.

While the exact sections vary by channel, most templates include the following types of sections.
​
Item Information

Contains the core product fields required by the marketplace, such as title, brand, identifiers, and condition-related information.

Defines how pricing values are sent to the channel, including listing price and other price-related fields depending on the listing format.

Controls how product descriptions and additional text content are sent to the channel.
​

Defines how product images from the catalog are mapped to the channel listing.

eBay templates include additional sections that allow you to manage category-related attributes.
​

This section allows you to browse or search eBay categories and configure mappings for category-specific attributes.
​

Different categories may require different fields (called Item Specifics), and these attributes appear here so they can be mapped to your catalog data.

Under each Category section, you can find the Variation Settings section, which is used when your catalog products include variations such as size, color, or material.
​

In this section you map the variation types from your 3Dsellers catalog to the variation types supported by the selling channel.

For example:

This mapping ensures that product variations are correctly structured and displayed on the marketplace listing.
​

If your products do not use variations, this section can usually be left unchanged.

Each field in the template can be mapped to a data source from your catalog.

To configure a mapping, click the edit icon next to the field.

When mapping a field, you can choose different sources for the value.

Use values from your catalog product data, including:

This is the most common type of mapping.

Allows you to enter a static value manually.

This value will be sent to the channel for all listings using this template.

Example:

Rules allow you to transform or calculate values dynamically based on conditions.

For example:

Rules are useful for more advanced automation.

Lookup lists allow you to convert values from your catalog into different values required by the channel.

Example:

Catalog condition → eBay condition value

Lookup lists are useful when marketplaces require specific value formats.

Most mappings support fallback values.

A fallback is used when the main mapping source does not contain a value.

Example:

If the subtitle is empty, the system will automatically use the product title.

The mapping interface includes a Preview Product feature.

This allows you to test your template with a real catalog product.

To preview a mapping:

This helps verify that mappings, rules, and fallbacks are working correctly.

Mapping templates include an Autofill required fields with AI option that helps automatically populate required listing fields when they are missing values.
​

When enabled, the system analyzes the product data in your catalog and uses AI to generate appropriate values for required attributes that are not mapped or do not have a value.
​

This feature can help fill fields such as:

To use this feature:

Before clicking to Autofill with AI:

​After clicking to Autofill with AI:

The generated values can then be reviewed and adjusted before saving the template.

Tip: AI autofill is especially useful when configuring mappings for new categories that have many required attributes.

Ensure all required fields have mappings before configuring optional fields.

Fallback values help prevent missing information in listings.

Always preview mappings with sample products before publishing listings.

Use clear template names such as:

This makes it easier to select the correct template when publishing products.
