When this fires

When a pending payment link is canceled before the customer pays it. A canceled link can no longer be paid.

Payment links never expire on their own — there is no expiry event. A link stays payable until it is paid or explicitly canceled.

The event fires the same way regardless of which payment provider processes the charge.
