The structure of our SKUs is determined by the product dimension group of the variants. This field is available in the Get /Catalog/Products API function. Every variant for a product has the same product dimension group.
The possible values are (some product dimension groups might not be used anymore):
| Product Dimension Group | Dimensions | Example (might not be actual variants) |
| 300 | Configuration | 020056-05, where Configuration = 05 |
| 400 | Size | 960865-01, where Size = 01 |
| 500 | Color | 861266-166, where Color = 166 |
| 600 | Configuration-Size | 920701-01-U, where Configuration = 01 and Size = U |
| 700 | Configuration-Color | 890292-01-001, where Configuration = 01 and Color = 001 |
| 800 | Size-Color | 861070-L-001, where Size = 800 and Color = 001 |
