Merchant orders, channel transactions and settlement batches are held in three ledgers, with amounts stored as integer cents.

Implementation and exception handling

Duplicate callbacks are deduplicated by channel transaction ID. Reversals create new records rather than overwriting the original transaction.

Operations records

Design record YF-PAY-RFC-202601. The regular maintenance window is Wednesday, 22:00–23:00. Changes involving service interruptions are announced separately on the status page.
