Hi, I have got an email from "Bank of America" with following information: Dear Valued Client: Effective October 2016, Mastercard mandated that all authorizations contain an authorization type identifier. This identifier shows if you obtain a pre, final or unidentified authorization when you process a customer’s card for a transaction. According to our records, you are processing on the TSYS platform and your processing solution has not been enhanced to include the required authorization type identifier. What do you need to know? All clients were notified of this requirement in the annual Release communications in 2016 and 2017. TSYS has contacted their certified partners regarding this mandate. Mastercard has recommended that your third party software provider set the authorization type identifier to pre-authorization or final authorization. Due to upcoming changes scheduled for June 2018 which will limit the number of undefined authorizations allowed, an authorization type indicator of undefined should not be frequently used. You must contact your third party software provider immediately to request that these changes be made according to the TSYS specifications that are utilized by your processing solution. My Application is using c# code and "payflowpro.paypal.com" anyone has any idea how to implement or resolve this issue?
