Hi,
I am doing the same thing now. I have trying to convert the woocommerce website into a mobile native and thought the woocommerce api would be the best way to get there. However, its hard to even see the products in any kind of way without the authentication. Learning for the development purpose and seeing how things work.
Example: As a customer, I would want to view the product and buy them. I would not concerned about the authority part other than the security that my credentials are not lost.
This brings me to this, since you are the plugin contributor, any specific tutorials or posts that shows this aspect of woocommerce api.
Kind Regards,
Saroj
