Payment Attempts are usually a feature of a subscription. When you create an invoice featuring a subscription, the invoice is sent to the client for payment. Once paid, a secure reference to their payment card is stored alongside the subscription.
When its time for the subscription to be re-charged, we make attempts to charge the client using their stored card. Sometimes this will fail, typically due to the client's card issuer declining the transaction, or due to the card having expired. In this instance, we notify the client that the payment was not successful, and invite them to supply new card details.
This happens with no notification to the merchant, who would otherwise be unaware that a payment was tried but was unsuccessful, so we store each attempt and display them when viewing the invoice. This is to let the merchant know that attempts were made, and why they were unsuccessful.
Note: client card details are never seen, transmitted or stored on Tascuro.com, and Tascuro has no access to these details. They are stored in a PCI compliant manner by our payment processor "Stripe".
