PaymentGate Enhancements - CSV Register and Uniqueness Check

Dear friends,
By your numerous requests, the ability to receive a payment register in csv format has been added to PaymentGate.
For correct accounting of payments in PaymentGate, the requirement for mandatory uniqueness within the project (previously within the file) of the client's payment number (parameter A in the recipient list file or transmitted via API) has also been added. Payments with non-unique numbers will not be processed.
Note that a search by the client's payment number has been implemented on the Payments (PaymentGate) page.
