What I worked on
  • Data modelling, custom migration app and bulk import.
The challenge

The source data held one product per colour. In Shopify those had to collapse into a single product with colour options and variants, which meant transforming the catalogue before importing it.

Implementation
  1. 01Source products grouped by product name so same-name/different-colour records become one product with variants and options.
  2. 02Custom Shopify app created from the Shopify Partner Dashboard using the legacy app/token flow available at the time.
  3. 03Shopify Admin API bulk product mutations used to write the transformed catalogue.
