The triPOS service accepts a American Express (Amex) Debit in several transactions.
Typically, most of the configuration values for triPOS are specified in the triPOS.config file. The isAmexDebitAllowed parameter in the triPOS.config file
allows to accept amex debit card when tap or inserted during the transaction.
triPOS cloud can modify amex debit settings using PATCH /cloudapi/v1/lanes/{{laneId}}/configuration endpoint:
isAmexDebitAllowed = true, amex debit is enabled for all the transactions, if amex debit card is tap or inserted during the transaction.
