Variations API

Same product. Different size, flavor, or form. Connected.

The Prodx Variations API links product variants together across size, flavor, form, scent, and other attributes. One API call returns every variation of a product with the specific attributes that differentiate them. Shoppers stay on the page and find exactly what they need.

Why Variant Discovery Creates Friction

Shoppers find the right product type, then have to search again for another size, flavor, or form because the catalog does not connect variations cleanly.

Disconnected Variants

Catalog variants exist, but the shopper experience treats them like separate products.

Manual Mapping Does Not Scale

Rules built SKU by SKU break as catalogs change.

Lost Revenue on PDP

When shoppers cannot pivot between variations on-page, they abandon or settle.

How Prodx Connects Product Variations

Prodx defines variation logic at the category level using standardized attribute values and category-specific QualityTypes, then applies that logic automatically across the catalog.

Returns variation groups such as Size, Type, Flavor, or Form from a single API call.
Uses standardized attribute values rather than manual SKU-level links.
Supports category-level rules so logic scales automatically to new products.
Can extend across related categories using a broader structures system when needed.
Powers variant selectors, PDP toggles, comparison views, and cross-category storytelling.
