Creating a Custom OAuth Application

WordPress uses the OAuth authentication standard, which requires the authenticating user to interact with WordPress via the browser.

Procedure

The following steps install the OAuth 2.0 plug-in and registers the provider in the WordPress admin console, creating what WordPress calls a "connected app". They also generate the OAuth credentials for OAuthClientId and OAuthClientSecret, which are needed to establish a connection for various authentication methods, as described in Establishing a Connection.

1. Log into your site through the WordPress admin panel.
2. Install the OAuth2 Plugin.
   To install the plugin manually:
   1. Download the plugin folder.
   2. Copy the downloaded folder to the wp-content\plugins folder.
   3. In the WordPress admin interface, use the Plugins menu to activate the plugin.
3. Navigate to OAuth Server > Add New Client.
4. Fill in all required fields. Set CallbackURL to http://localhost:portnumber.
5. Click Create Client. The admin panel displays the Client Id, Client Key, and Client Secret. Record these values for future reference.
6. Navigate to Users > Applications > YourAppName and approve your new application.
