You can view the payments within a file by clicking on a particular payment file either on the 'All files' or 'My unconfirmed files' tab.
The list of payments includes the execution date, sender account, sender name, receiver account, receiver name, amount, currency and payment status. It also shows additional information messages (if any) and whether rejected payments (if any) have been checked.
If you want to view more payment details, click the payment row to expand it.
You can narrow down the payments by searching for a word, execution date, signer ID, sender account, payment status or currency, or by using the filters above the list.
