  • they said that or what i got is first i need to create product with 1 deafault sku, that’s okay i am able to create.
    but if you want multiple skus creation.
    you need to specify them in sku-properties fields and the use SKU creation api to create skus with product ID, they will be auto associate,

→ the main thing i need help if i am doing wrong in sku-properties:

Thank you.
