# Sources now provide a recommended value when the issuer advises using 3D Secure ## What’s new Adds `recommended` as a possible value for a `Source` object’s `card[three_d_secure]` property. Previously, the only valid values were `not supported`, `optional`, and `required`. ## Impact Adding a `recommended` value to the `card[three_d_secure]` property of the `Source` object provides more nuanced information about 3D Secure availability. You can now identify cases where 3D Secure is suggested but not mandatory, allowing for more informed decision-making in payment processing. ## Upgrade #### REST API 1.
