How do I view all the details of a transaction? Open the Transaction History screen by clicking on the Recent Activity button on ROAMmerchant’s App Dashboard. You will now be presented with the full transaction history associated with your account. Find the transaction that you would like to view more details about. Once located, click anywhere on the row to expand the full details of the transaction. For additional support, please refer to the Support Page in your merchant portal or contact your ISO contact.
