AJAX Actions and WP-CLI

The addon has no REST API and no custom database tables. Dynamic behavior runs through WordPress AJAX (admin-ajax.php), and one maintenance task is available through WP-CLI.

AJAX actions

Read-only, front-end (available to guests, nonce-verified):

Action	Purpose	Nonce
reign_load_courses	[modern_courses] filter and load-more	reign_courses_nonce
reign_filter_groups	[modern_groups] filter	reign-modern-groups
reign_load_more_groups	[modern_groups] pagination	reign-modern-groups
reign_learndash_lms_get_course_participants	Paginated participants list	ajax-nonce
rtm_ld_atc_woo_product	Add the linked store product to the cart	reign-ld-buy-course

Admin-only (authenticated, nonce + capability):

Action	Purpose	Capability
reign_ld_migrate_reviews	Run the review migration	manage_options
reign_ld_check_migration_status	Poll migration progress	manage_options
reign_ld_sync_group	Bulk-join a course’s users into the linked BP group	manage_options
reign_ld_get_linked_groups	List BP groups linked to courses	manage_options
reign_dismiss_ld_groups_slug_notice	Dismiss the groups slug-conflict notice	edit_posts

The guest-facing cart action validates the nonce, sanitizes the product IDs, whitelists the purchase method, and confirms the product is genuinely linked to the course before acting.

WP-CLI

One command is registered:

wp reign-ld migrate-reviews

It migrates existing reviews into the addon’s comment-based review format, the same operation as the admin Review Migration page. Use it for scripted or large migrations. See Course and group reviews.

What the addon does not add

• No REST API namespace or endpoints.
• No custom database tables.
• No custom post types, taxonomies, capabilities, or cron events.

Persistence is entirely WordPress options plus post, group, user, and comment meta.
