WebServices API for create products with a mix of attributes

Hello,

I'm trying to create product with multiple attributes with the API.
I use this library :
https://github.com/PrestaShop/PrestaShop-webservice-lib

It's OK for a simple product, but is there a documentation or an advised method for create a product with by example a mix of 2 colors and 2 sizes ?

I think there is two solution : create all variations in one time or make a special part in the code for each variation (4 in my case, 2 colors and 2 sizes)

I've check in the official doc here without success, there is no details : https://devdocs.prestashop.com/1.7/development/webservice/tutorials/prestashop-webservice-lib/

Please, maybe someone have a idea ?

Review the PrestaShop-webservice-lib repository and the linked Webservice tutorial first, focusing on how product attributes and combinations are represented. Done means adding documentation that clearly explains the advised method for creating a product with multiple colors and sizes, with a concrete example if the existing material supports one.
