| 10 September 2026 | v1.1.0                | Q3 2026      | We are introducing support for [Mastercard Account Catalog Services](https://developer.mastercard.com/account-catalog-services/documentation/api-reference/account-catalog-services-api/) to manage the **Mastercard One Credential** product for PAN-less issuers. This enables issuers to: • Register, update, and delete Account Level Management Product Rules by using a `cardContractId`. • Receive a ready-to-forward encrypted (JWE) payload without requiring a clear PAN. [oas_mastercard_services_v1.1.0.yaml](https://static.developer.mastercard.com/content/mastercard-processing-mastercard/uploads/oas_mastercard_services_v1.1.0.yaml) (52KB) |
