How to find post type slugs
When using a custom post type in Reactor, you need to input the slug name, which is not always obvious.
To find a post type slug, login to the WordPress admin area on your website. Click on the post type in the left menu, such as Events. Look at the web address bar url, the last part is the post type slug.
In the image below, the post type slug is "tribe_events". That is what you would add to Reactor under "Custom Post Type."
A post type slug will not contain capital letters, spaces, or special characters.
