CAC Bank is an OTP debit with no redirect and no webhook: initiate SMSes a
code to the payer's mobile, and the charge only settles when that code is
confirmed. The payment service already spoke it (passenger uses it); the
freight side had the enum values but none of the flow.
API:
- PaymentClientService.confirmOtp forwards the code to
POST /payments/intents/:id/confirm, mapping 400/404 to BadRequest so a
mistyped code stays retryable instead of surfacing as a gateway failure.
- PaymentService.confirmOtp is keyed by the LOCAL intent id (the invoice's
paymentId) rather than the domain reference, so the right invoice settles
when several share a booking. On success billing settles the invoice.
- payInvoice rejects CAC_BANK without payerAccount before calling the
gateway, and no longer runs the demo auto-settle for a COLLECT_OTP intent
(it is not paid until the payer confirms).
- POST /billing/my-invoices/:id/confirm — ownership-checked, and since
warehouse fee invoices are central invoices it covers those too.
Portal:
- useInvoicePayment owns the whole flow (initiate, redirect-or-OTP, confirm)
and replaces the five near-identical pay mutations at the call sites.
- PaymentMethodModal gains the CAC Bank option, the payer mobile field, and
the OTP step. Click-outside is disabled there so a stray click cannot drop
the payer out of a live OTP window.
