  | Deposit                    | `grandcentral-deposit-api`           | 1.3.0   | Added APIs to get cards by account ID and unlink a card                                     | The deposit API now supports retrieving the cards linked to an account and unlinking a card from an account.                                                                                                                                                                                                                                                                                                                                                              |
  | Deposit                    | `grandcentral-deposit-api`           | 1.3.0   | Added retail and business line-of-business support to the deposit API                       | The deposit API now accepts the `Open-Banking-Lob` HTTP header to route requests to either the retail or business instance.                                                                                                                                                                                                                                                                                                                                               |
  | Message                    | `grandcentral-message-api`           | 1.0.3   | Added the message API to the Grand Central API BOM                                          | The `grandcentral-message-api` is included in the Grand Central API BOM for the first time in v2026.06. The specification defines endpoints for searching messages, with pagination metadata and a `messages.messageList` response envelope so consumers can iterate large result sets predictably. v1.0.3 wraps the response in this envelope; the endpoints themselves are unchanged from earlier versions.                                                             |
  | Payment                    | `grandcentral-payment-order-api`     | 2.0.3   | Extended payment order API with IBAN directory source and richer intermediary agents schema | The `grandcentral-payment-order-api` now aligns with the payment order standards: <ul><li>Added the `IBAN-DIRECTORY` value to the `bankDirectorySource` property, so payment orders can identify banks through the IBAN directory.</li><li>Extended the `intermediaryAgents` schema with `partyName` (max 140 characters) and `paymentInstructionAccount`, so channels can carry the intermediary agent's legal name and account alongside the BIC and address.</li></ul> |
  | Payment                    | `grandcentral-payment-order-api`     | 2.0.3   | Changed `lastPaymentDate` to use ISO 8601 date-time format                                  | The `lastPaymentDate` field on `vendorSpecificAttributes` is now an ISO 8601 date-time (for example, `2026-03-01T10:15:30Z`) instead of a calendar date. Channels and connectors that integrate with v2 must emit timestamps rather than calendar dates for this field.                                                                                                                                                                                                   |
