Update - You can use multiple ways: The built-in function wcs_get_subscriptions() which accepts specific arguments. In your case, to get all subscriptions, you will use: $subscriptions = wcs_get_subscriptions(['subscriptions_per_page' => -1]); You will get an array of Subscription protected objects where you can use on each object the WC_Data get_data() method, to access the data: $subscriptions = wcs_get_subscriptions(['subscriptions_per_page' => -1]); // Loop through subscriptions protected objects foreach ( $subscriptions as $subscription ) { // Unprotected data in an accessible array $data = $subscription->get_data(); print_r( $data ); // Display the subscription raw data array } Related: Get Subscription Product author of a Woocommerce subscription You can also use a SQL query to get all subscriptions A SQL query can be lighter and allows more filtering. This way you can get only the required data in a more effective way. As subscriptions are a Wordpress custom post type, You can get all subscriptions IDs first. Then in a foreach loop you will be able to get the WC_subscription object. global $wpdb; // get all subscriptions IDS $subscriptions_ids = $wpdb->get_col(" SELECT ID FROM {$wpdb->prefix}posts WHERE post_type LIKE 'shop_subscription' "); // Loop through subscriptions Ids foreach($subscriptions_ids as $subscription_id){ // Get an instance of the WC_Subscription object $subscription = new WC_Subscription( $subscription_id ); $data = $subscriptions->get_data(); print_r( $data ); Display the subscription raw data (unprotected accessible array) } Then with the $subscription object and the $subscription_id you will be able to do what you want, using WC_Subscription methods to get the desired data or the using subscription ID on dedicated functions.
