Hey there!
I am Alexander. I am a PHP developer. I have worked with the woocommerce REST API in the past and used it for creating products, importing products, retrieving categories and so on.
I can make an implementation for you using pure PHP. You will get 2 scripts. One that has a form , and the second one that allows you to configure spefic variables. Both scripts will be based on a function that I will write and you only have to invoke it .
ex: Create_Woocommerce(name,sku,category)
Anyways, Give me a message.
Alexander
