Expired Listings not being Trashed

For anyone else that is seeing a bug where Listings aren’t being deleted/trashed in WordPress when they are expired on the IDX side, I wrote a little tool that shows you all of the expired listings in your Listings post type:

/**
 * Adding expired listings page
 */
function pp_idx_admin_page() {
	add_submenu_page(
		'edit.php?post_type=listing',
		'Expired Listings',
		'Expired Listings',
		'manage_options',
		'expired_listings',
		'pp_expired_listings_view'
	);
}
add_action( 'admin_menu', 'pp_idx_admin_page' );

/**
 * Creates the view for the expired listings page
 */
function pp_expired_listings_view() {
	$nonce           = isset( $_POST['_wpnonce'] ) ? sanitize_text_field( wp_unslash( $_POST['_wpnonce'] ) ) : false;
	$expired_request = wp_verify_nonce( $nonce, 'mls-expired-nonce' ) ? $_POST : false;

	// Retrieve applicable query parameters.
	$mls_base_url = isset( $expired_request['mls_base_url'] ) ? sanitize_text_field( $expired_request['mls_base_url'] ) : null;

	if ( $mls_base_url ) {
		update_option( 'mls_base_url', $mls_base_url );
	} else {
		$mls_base_url = get_option( 'mls_base_url' );
	}
	?>

	<div class="wrap">
		<h1>Expired Listings</h1>

		<p>Warning: This does check for a 404 on the mls url so it might take a bit to run. Don't run this excessively.</p>

		<p>You can use the Edit button in the Result to Trash the listing.</p>

		<form method="post">
			<label for="mls_base_url">MLS Base URL</label>

			<input type="hidden" name="_wpnonce" value="<?php echo esc_attr( wp_create_nonce( 'mls-expired-nonce' ) ); ?>">

			<input type="text" required name="mls_base_url" id="mls_base_url" value="<?php echo esc_url( $mls_base_url ); ?>" placeholder="https://mls.myagency.com" class="regular-text">

			<input type="submit" name="submit" value="Check Expired Listings" class="button button-primary">

			<?php
			if ( isset( $_POST['mls_base_url'] ) ) {
				$args = array(
					'post_type'      => 'listing',
					'posts_per_page' => -1,
				);

				$all_listings = get_posts( $args );
				$mls_urls     = array();

				foreach ( $all_listings as $listing ) {
					$mls = get_post_meta( $listing->ID, '_listing_mls', true );

					array_push(
						$mls_urls,
						array(
							'url'  => "$mls_base_url/idx/moreinfo/b232/$mls",
							'type' => 'GET',
						),
					);
				}

				$requests    = Requests::request_multiple( $mls_urls );
				$has_expired = false;

				foreach ( $requests as $key => $request ) {
					if ( ! property_exists( $request, 'status_code' ) ) {
						continue;
					}

					if ( 404 === $request->status_code ) {
						$has_expired     = true;
						$expired_listing = $all_listings[ $key ];
						?>
						<p>
							<a href="<?php the_permalink( $expired_listing->ID ); ?>">
								<?php echo esc_html( $expired_listing->post_title ); ?>

						</p>
						<?php
					}
				}

				if ( ! $has_expired ) {
					echo '<p>No expired listings found.</p>';
				}
			}
			?>
		</form>
	</div>
<?php } ?>

You can either put this code in a new plugin or in your functions.php file. This is pretty rough, so use at your own risk, but wanted to share my workaround for others that ran into this issue.
