Find the Post Type
If you want to create a form but do not know the post type your plugin or theme is using here is how to find out the post typer.
The easiest way to find out the post type is to visit the create or edit view of your plugin post type and then check in the url post_type="the post type" name.
Alternatively you can look over all available post types in the form settings control panel and try to predict the post type. Usually it is named after the plugin.
