WooCommerce: Get All Subscription Products in WordPress

I was working on adding WooCommerce subscription support to the LoginWP plugin and wanted to get a list of all WooCommerce subscription products or products that are subscriptions (including simple and variable subscriptions) in your WordPress e-commerce shop.

Below is the code I came up with that worked for me. Hopefully, you find it useful.

wc_get_products([
    'type' => array( 'subscription', 'subscription_variation', 'variable-subscription' )
]);

See WC_Product_Query::get_default_query_vars() for a list or arguments supported by wc_get_products().
