There are several approaches which can be used to handle chargeback delivery to the merchants and chargeback disputing. As the number of transaction volumes processed (and respective numbers of chargebacks issued) grew, new approaches were introduced. The progress of chargeback handling technologies continues even now.
When it comes to chargeback delivery, the most traditional approaches included regular mail and fax. Originally, chargeback information was simply sent to merchants in the form of printed letters or reports. Later on, regular mail and fax were replaced by e-mails. Presently some processors implement the logic, which allows their systems to generate a data file associated with a chargeback. The file can be downloaded by a merchant, or simply available on the merchant’s FTP. Finally, some processors use special APIs, which can automatically notify merchants when new chargebacks occur.
When it comes to chargeback disputing, fax still remains one of the predominant options used by merchants to send the information about the original charge. This information can also be sent by e-mail. A more sophisticated approach involves a data-file, including the key information about the charge, and a fax or e-mail, used to send the supporting documentation. The most advanced options include special chargeback disputing portals and APIs.
