I see that I can create al most 250 products for my extension. Since I need to create a lot of them there is a tool that help me do this or should I create one-by-one from developer console?
You can use the API
I see, time to create a little POST tool
Btw I see that I can’t delete a products, only deprecate them. The limit is on entire products (active + deprecated)?
Correct
That is not so good, if I change my mind in the future than I’m stuck
You can freely change names and prices of SKU’s after creation.
So ratehr than kill a product use the product for something else.
