[WooCommerce Variation Swatches and Photos] #wpallimport #woocommerce #swatches

import-variation-swatches.md

This is an example snippet that imports swatches added by this plugin: https://woocommerce.com/products/variation-swatches-and-photos/. This example only works with the variation attribute "Colour" and it uses the images uploaded to the variations as the swatch images. It is highly likely that you will need to modify it for your specific use case.
