2026.06 - Grand Central Documentation

Features

The following feature updates are available in 2026.06 for Grand Central Unified APIs:

Product group	Software component	Version	Title	Description
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: Added the `IBAN-DIRECTORY` value to the `bankDirectorySource` property, so payment orders can identify banks through the IBAN directory. 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.
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.
Payment	`grandcentral-payment-order-api`	2.0.3	Added retail and business line-of-business support to the payment order API	The payment order API now accepts the `Open-Banking-Lob` HTTP header to route requests to either the retail or business instance.
Servicing Consent	`grandcentral-servicing-consent-api`	1.5.0	Added retail and business line-of-business support to the servicing consent API	The servicing consent API now accepts the `Open-Banking-Lob` HTTP header to route requests to either the retail or business instance.
Party Lifecycle Management	`grandcentral-party-lifecycle-api`	1.7.0	Added support to receive push notifications from an identity verification vendor	Grand Central can now receive identity verification results from a partner vendor once the verification workflow is complete and the results are available for consumption.
