Looking for a way to display your most commented Disqus posts on your WordPress site? We just released a WordPress plugin that will allow you to do just that. The plugin integrates with the Disqus API and pulls in your most popular threads (most commented posts). It can be added to your site via widget, template tag, or shortcode.
You can download the Disqus Popular Threads Widget here.
Before you get started, you’ll need to get a Disqus API Key. Here are the instructions:
Visit the Disqus API Page
Click on Applications tab at the top.
Click on the get started link to register your application.
Enter your Application Name, Description, Website Name and click Register. Now that the application is registered, let’s go get that Public Key.
Go back to the Applications tab and click on the “configure a trusted domain” link under Public Key.
From the settings tab, scroll down to “Settings” and enter your domain name. Click “Save Changes” at the bottom of the screen when done.
Note, your domain needs to be listed here in order for the plugin to work on your site.
When you go back to the Applications tab you should now see your Public Key listed.
