Understanding Model ID, Config ID, and Variant Structure for Zalando
To ensure correct product grouping and variant display on Zalando, it’s essential to structure your data consistently. This guide explains how Model ID, Config ID, and variant attributes work together.
Model ID
The Model ID groups all variants of a product into a single product listing on Zalando.
- All items with the same Model ID are treated as one product
- Different sizes and colors should share the same Model ID (if they belong to the same product)
Example:
A T-shirt available in multiple colors and sizes → all variants share the same Model ID
Config ID
The Config ID is used to split a product into color-based variants.
- All items with the same Config ID represent one color
- Each color should have its own unique Config ID
Example:
- Blue T-shirt → one Config ID
- Red T-shirt → another Config ID
Color and Size Attributes
These attributes control how variants are displayed and selected on Zalando.
- Color defines the visual grouping (linked to Config ID)
- Size defines the selectable size options within each color
How It Works Together
- Same Model ID → Same product page
- Same Config ID → Same color variant within that product
- Color + Size → Controls how options are shown to the customer
Best Practices
To ensure correct grouping and display:
- Keep Model ID consistent per product
- Keep Config ID consistent per color
- Ensure Color and Size attributes are accurate and complete
