Release Notes for July 26, 2022

Discontinuing old versions of SSL and Standardizing TLS Suites

• Lithic will be deprecating support for TLS 1.0, TLS 1.1, and TLS 1.3 for clients accessing api.lithic.com, api.privacy.com and the Lithic Dashboard.
  • api.lithic.com currently supports TLS 1.0, 1.1, and 1.2 - we'll be dropping 1.0 and 1.1
  • api.privacy.com currently supports TLS 1.2 and 1.3 - we'll be dropping 1.3
  • Both will only support 1.2
  • The list of supported TLS ciphers will be changing, the result will be both domains will match each other but neither will match its current state. Please reach out to us with any questions about the new supported list of cipher suites
• TLS 1.0 and 1.1 have been deprecated by major web browsers since 2020, and customers should upgrade their API clients if they do not support more modern protocol versions.
• Note: this change is already live on our sandbox environment.

Including Cash Back and Foreign Exchange Rates in ASA requests

• A new field cash_amount will be included on the ASA request body when the cardholder is requesting cash back on top of their purchase amount. In a future release, customers will be able to decline the cash back portion of the request. The cash amount is always in the settlement currency.
  • Note: for customers that were participants in the beta program for this feature, cash_back will contain the same value. After a migration period, cash_back will be removed and beta customers will be required to migrate implementations to use cash_amount.
• A new field conversion_rate will be included on the ASA request body when the conversion rate between the requested cash amount and the settlement currency is known. This field can be used by customers to determine the conversion from cash amount in the local currency to the cash amount in the settlement currency.
