We've implemented the Encrypted Ephemeral Storage (EES in short), a service consumed by the Public API to generate a limited time token. The token will replace the payment details information when placing an order via API, providing merchants that use the 2Checkout API with increased security for their transactions.
We increased the number of IPN/LCN endpoints that can be set from the Merchant Control Panel, from 3 endpoints to 4, which enables merchants to increase the number of their integrations.
