JSON API Plugin, that is required, was closed on August 7, 2019 from WordPress repository. You can download JSON API Plugin from https://github.com/PI-Media/json-api until it is republished and available on WordPress.

  • Validate Auth Cookie

  • Get Current User Info

For documentation: See ‘Other Notes’ tab above for usage examples.

  • Call to generate_auth_cookie endpoint using Postman
  • Call to get_currentuserinfo endpoint using Postman
  • Call to validate_auth_cookie endpoint using Postman


First you have to install the JSON API for WordPress Plugin (https://wordpress.org/extend/plugins/json-api/installation/). or You can download JSON API Plugin from https://github.com/PI-Media/json-api

To install JSON API Auth just follow these steps:

  • upload the folder „json-api-auth“ to your WordPress plugin folder (/wp-content/plugins)

  • activate the plugin through the ‘Plugins’ menu in WordPress or by using the link provided by the plugin installer

  • activate the controller through the JSON API menu found in the WordPress admin center (Settings -> JSON API)


Thanks to ‘mattberg’ who wrote the auth controller (https://github.com/mattberg/wp-json-api-auth) initially. I have added few methods and authored it as a WordPress plugin so that it could easily be searched and installed vis WordPress.

  • There are following methods available: validate_auth_cookie, generate_auth_cookie, clear_auth_cookie, get_currentuserinfo

  • nonce can be created by calling http://localhost/api/get_nonce/?controller=auth&method=generate_auth_cookie

  • You can then use ‘nonce’ value to generate cookie. http://localhost/api/auth/generate_auth_cookie/?nonce=f4320f4a67&username=Catherine&password=password-here

  • Use cookie like this with your other controller calls: http://localhost/api/contoller-name/method-name/?cookie=Catherine|1392018917|3ad7b9f1c5c2cccb569c8a82119ca4fd

For instance, you have a new controller ‘events’ and want to allow users to post new ‘event’ using ‘add_event’ method.
This is how you will call the end point with cookie and post the event with user info:


If you want sample code how it can be done, check ‘JSON API User’ plugin https://wordpress.org/plugins/json-api-user/. This Auth plugin is part of JSON API User plugin.

It needs ‘cookie’ var.


It needs username, password vars. seconds is optional.

Then generate cookie: http://localhost/api/auth/generate_auth_cookie/?username=john&password=PASSWORD-HERE

Optional ‘seconds’ var. It provided, generated cookie will be valid for that many seconds, otherwise default is for 14 days.

generate cookie for 1 minute: http://localhost/api/auth/generate_auth_cookie/?username=john&password=PASSWORD-HERE&seconds=60

60 means 1 minute.

Method: get_currentuserinfo

It needs ‘cookie’ var.

Hi, I am using the awesome JSON API plugin. I read I can’t have access to the posts postmeta unless I’m authenticated and I thought maybe your plugin is the solution to that. I have installed your plugin but not entirely sure how to use it in my application.
