Create new product with woocommerce REST API with javascript (clientside)?

If you’re using SSL (HTTPS URL) you don’t need to use oauth1.0 with oauth signature and everything. All you need to do is pass in the consumer_key and consumer_secret in the url

https://localhost/wpShop/wc-api/v2/products?consumer_key=ck_1111111111122123&consumer_secret=cs_232332322233232

That’s it! However, if your URL is NOT SSL, then you have to go to the trouble of creating an HMAC-SHA1 keys and all that.
