Cancel payment-card collection
Cancel the active secure collection of this type for the Session. If no matching collection is active, the request is accepted and has no effect. Cancellation is asynchronous: wait for the original collection operation’s sanitized terminal webhook with status: cancelled. Collected digits and the terminating key are never returned.
See the generated payment.* webhook operations for complete payload schemas and examples.
