REST API Issue over non HTTPS woocommerce_api_authentication_error

For http as per the docs we need to setup client library to make api calls

Not true, we have docs for it and you can do oAuth1.0 authentication by yourself:
https://woothemes.github.io/woocommerce-rest-api-docs/#authentication

If you want to use that library, go ahead, no problem, but you can put it in any folder.

https://www.example.com/wc-api/v3/ – I get the json response, but if i append https://www.example.com/wc-api/v3/orders or any other calls i get following erros

Because this library that you are using don’t support v3, just v2.

You can find our official libraries here: https://woothemes.github.io/woocommerce-rest-api-docs/#official-libraries

Thank you for your reply,

So if i want to use the official libraries https://woothemes.github.io/woocommerce-rest-api-docs/#official-libraries then how do i install in my woo-commerce files where do i need to add the code libraries(in woocommerce plugin folder).

Also, do i need to do any settings over my hosting, currently my website is hosted on digital ocean.
