Create/update stocks for combinations

[antonio.bellico]

Hello everyone, nice to be part of this group.

I am recently approaching Prestashop and I am trying to connect it to my Erp software.

I was able through the webservices calls to create an article, the color  and the combinations.

But I just don't understand how, update (put) or create a combination (post), a quantity (stock).

When I create a combination and pass it the quantity it does not work, but it enter '0'.

 

Could you tell me what is the call to load, modify quantity to a combination?

 

Thank you.
