It is currently impossible to get notified of new WordPress.org support forum replies without subscribing to each individual topic via email. See this Meta Track ticket for details.
So I created the Support Pilot plugin for WordPress that generates RSS feeds for support topics and replies for any plugin or theme on WordPress.org.
It works by parsing and combining the RSS feed of the 30 latest support support topics and the RSS feeds for replies to each of those topics.
How to Install
The plugin must be added as a Composer dependency to your site:
composer require kasparsd/support-pilot-plugin
composer install inside the plugin directory to install the necessary PHP dependencies.
How to Use
The plugin registers a new public feed endpoint
wporgreplies which supports
theme request parameters which must match the plugin or theme slug on WP.org:
PLUGINSLUG is the plugin slug on WP.org.
These feeds can be used to generate Slack notifications or any other automation that supports RSS feeds.
