Data API

The data API exists to provide additional data to Irving asynchronously. You can register a new data endpoint via the wp_irving_data_endpoints filter. You must provide a slug and callback method. Here's an example:

add_filter(
	'wp_irving_data_endpoints',
	function( $endpoints ) {
		$endpoints[] = [
			'slug'     => 'books-data',
			'callback' => 'get_books_data',
		];
		return $endpoints;
	}
);
