Please let me know whether you have any questions?

You can read guide about REST API.
http://alankent.me/2015/07/24/creating-a-new-rest-web-service-in-magento-2/

I read & practice and now I can do anything about REST API.

Wishlist is integral part for any eCommerce platform and We wish Magento guys would have included them in the core features. So we have taken the initiative and added these features by taking out the fork from the github. We are waiting for Magento guys to Merge our pull request. In the meanwhile you can take use the following forks for your online store:

WishList: https://github.com/manish-ip/magento2

Or you can download our free plugin from the following link :

WishList API Plugin: http://www.ipragmatech.com/products/wishlist-rest-api-magento/

Try this it will help to you.
