Auto Debit APIs

When enabling the Transport Code service, the user agrees to and signs the Auto Debit agreement to enable the service. After that, Alipay+ can automatically deduct the fare after the user finishes the ride.

The following APIs are used in Transport Code Auto Debit:

Note: In the Transport Code scenario, the MPP must support Auto Debit for in-store payments.
