Working with Unsubscribe Buttons
Let subscribers cancel their active subscriptions by adding Unsubscribe buttons to your
website.
How PayPal Cancels Subscriptions
When subscribers cancel subscriptions, they avoid future recurring payments. If subscribers
cancel their subscriptions before payment is sent on the due date for the recurring payment,
PayPal cancels their subscriptions immediately and does not deduct the payments.
The following example shows how subscribers use Unsubscribe buttons to cancel their
subscriptions.
