Extends the JSON API Plugin to allow RESTful user registration, authentication and many other User Meta, BuddyPress functions. A Pro version is also available.

==Description==

JSON API User extends the JSON API Plugin with a new Controller to allow RESTful user registration, authentication, password reset, RESTful Facebook Login, RESTful User Meta and BuddyPress xProfile get and update methods. This plugin is for WordPress/Mobile app developers who want to use WordPress as mobile app data backend.

Features include:

• Generate Auth Cookie for user authentication
• Validate Auth Cookie
• RESTful User Registration
• RESTful Facebook Login/Registration with valid access_token
• RESTful BuddyPress xProfile fields update
• Get User Meta and xProfile fields
• Update User Meta and xProfile fields
• Delete User Meta
• Password Reset
• Get Avatar
• Get User Info
• Post Comment

The plugin was created for mobile apps integration with the web app using WordPress as backend for all the data. WordPress helped in putting together the web app quickly and then Mobile iOS and Android apps were integrated via this plugin. There were some app specific customized methods which are not included but rest have been made generic for community usage.

My other JSON API Auth plugin has also been integrated with this from version 1.1. since most methods required user authentication via cookie for data update. You can also write your own methods by copying the existing methods if you need any user related features.

Hope this will help some.
