How can I track a failed transaction in PrestaShop and disable notifications?

When a transaction is created in PrestaShop, this message is sent to Wallee to create a payment transaction. During the creation, the generated order ID is passed along. This ID will appear on the customer's bank statement as well as on your payout report as the merchant.

If a payment fails, the transaction is marked as failed. A new transaction will be created repeatedly until the merchant successfully completes the payment for the shopping cart. Since every failed order is stored in the PrestaShop database, the merchant can see in the PrestaShop backend if a buyer has attempted to pay their cart multiple times.
