WooCommerce allows e-commerce website owners to sell products and services with recurring payments. For this purpose, it offers the WooCommerce Subscriptions extension that provides two related items,  subscription products and subscriptions . 

The API2Cart API is integrated with the extension. It returns subscription data in the subscription_info field of the product.info  and  product.list  API methods. Below you can see an example response in the field: 

              
              "subscription_info":[  
                {  
                    "subscription_price":500,
                    "subscription_period_interval":1,
                    "subscription_period":"month",
                    "subscription_period_length":0,
                    "sign_up_fee":0,
                    "trial_period":"day",
                    "trial_period_length":0,
                    "one_time_shipping":false,
                    "subscription_limit":"no"
                }
              ]
