I want to confirm that a customer subscription has been cancelled. The Stripe API documentation only refers to returning "active" subscription. How can I get a listing of all the subscriptions?
Listing subscriptions
You can see a list of the customer's active subscriptions.
GET https://api.stripe.com/v1/customers/{CUSTOMER_ID}/subscriptions
Retrieving a customer's subscription
By default, you can see the 10 most recent active subscriptions stored on a customer directly on the customer object, but you can also retrieve details about a specific active subscription for a customer.
GET https://api.stripe.com/v1/customers/{CUSTOMER_ID}/subscriptions/{SUBSCRIPTION_ID}
