This plugin will add additional meta data information about your WooCommerce subscription. The API data will add the following information to the WooCommerce Order endpoints:
- subscription_id – The ID of the subscription.
- no_of_orders – The total number of orders from a subscription.
This plugin was developed to help companies identify how many orders are within a subscription so they may apply filtering on their end (such as shipping on every other order).
