Good afternoon,
I would say that I am synchronizing (post, put) products in prestashop 1.7 and I get a problem when adding products with combinations. When I add a product X with combinations X1, X2 in the webservice / api / products / ... page and I have the combinations X1, X2 well created, the stocks_availables of X1 and X2 do not appear. So I can't update my stock. All this from webservice api.
Only from the backoffice, when I edit and save the existing product X again, the available stocks of these combinations appear. Thank you.
