## 15 April 2022 [#15-april-2022]

Added support for Card on File, SCA Exemptions for Braintree and PayPal.

## 30 January 2022 [#30-january-2022]

* Added [Strong Customer Authentication (SCA)](/api/nvp-soap/payflow/sca-exemptions/) information.

  > **Note:** **Note:** Merchants operating in the European Economic Area (EEA) are mandated to support Strong Customer Authentication (SCA) on ecommerce transactions to meet the Payments Service Directive 2/Regulatory Technical Standards (PSD2/RTS) regulations.
* Added `MERCHANTNAME` to [TSYS](/api/nvp-soap/payflow/integration-guide/additional-parameters/#tsys-additional-credit-card-parameters) dynamic soft descriptor capability.
* Added `PAR` and `PARID` for [American Express](/api/nvp-soap/payflow/integration-guide/additional-parameters/#payment-account-reference).

  > **Note:** **Note:** The [Payment Account Reference (PAR)](https://developer.americanexpress.com/products/payment-account-reference-public/overview) is a non-financial reference number assigned to each unique Primary Account Number (PAN) and mapped to all its affiliated Payment Tokens.
* Added support for [Card on File (CoF)](/api/nvp-soap/payflow/integration-guide/card-on-file/) for American Express.

## 15 July 2021 [#15-july-2021]

* Added clarification to [Card on File (CoF)](/api/nvp-soap/payflow/integration-guide/card-on-file/) that storing the credit card details locally requires use of the `CARDONFILE` parameter.

## 08 June 2021 [#08-june-2021]

* Added note that FISERV Nashville and Global Payments now supports [Card on File (CoF)](/api/nvp-soap/payflow/integration-guide/card-on-file/).
* Added note to [Payflow Header Parameters](/api/nvp-soap/payflow/integration-guide/header-parameters/) to not include `https://` in the Host URL field.
* Updated description of `RESULT=23` to note that no spaces, non-numeric characters or dashes are part of the `ACCT` value.

## 15 May 2021 [#15-may-2021]

* Added note throughout guide that ACH is no longer available for new accounts.
* Renamed First Data Merchant Services (FDMS) to FISERV due to new branding.
* Removed references to FISERV (First Data) South as this platform is deprecated.
* Removed `AUTHENTICATION_ID` from [3-D Secure with 3rd-Party Merchant Plug-ins](/api/nvp-soap/payflow/3d-secure-mpi/) as this field is only used in the Payflow Buyer Authentication Service.

## 16 April 2021 [#16-april-2021]

* Updated description of `RESULT=170` under [Transaction Responses](/api/nvp-soap/payflow/integration-guide/transaction-responses/#result-values-and-respmsg-text) to add additional information regarding fraudulent transactions.
* Added new response code `SUCCESSWITHWARNING`.

  > **Note:** **Whitelisted merchants:** If PayPal Risk flags a transaction as possibly fraudulent, Payflow ignores the reason and allows the transaction to process. Payflow returns a new response parameter called `SUCCESSWITHWARNING` with the reason why PayPal Risk declined the transaction. For example, `RESULT=0&RESPMSG=Approved&SUCCESSWITHWARNING=170:Fraudulent activity detected. Excessive use of card.`
  >
  > **PayPal merchants:** As PayPal is your acquiring bank, PayPal may reject a transaction based on its risk criteria. A `RESULT=170` could be generated whether the account is whitelisted or not. Whitelisting only prevents your account from being totally blocked to all transaction processing.
* Fixed example for Transaction summary report in the Payflow reporting guide.
* Added new additional parameters for **TSYS** under [TSYS additional credit card parameters](/api/nvp-soap/payflow/integration-guide/additional-parameters/#tsys-additional-credit-card-parameters).

## 27 April 2020 [#27-april-2020]

* Added the following note throughout the guide:

  Since Payflow is operating out of multiple data centers we highly suggest that all API calls are done using the host URLs above. Should you hard code the IP addresses to send transactions via the Payflow API, PayPal cannot be responsible should your transactions fail should a data center be offline due to any issues or any scheduled maintenances.
* Removed references to CyberCash - now deprecated.

## 28 December 2019 [#28-december-2019]

* Updated definition of 'RESULT' 170 to better reflect that it is now used for general fraudulent activity not just carding.
