The April 2026 release of B2B Gateway includes the following important notices.
Deprecation notice
Deprecated functionality is supported, but Informatica intends to drop support in a future release. Informatica requests that you transition to different functionality before the functionality is dropped.
Informatica replaces session IDs used for user authentication with JSON Web Tokens (JWT). The organization administrator can change the authentication type used for REST API requests on the Settings page in Administrator. If the administrator enables the JSON Web Token (JWT) authentication type, browser-based user interface communications seamlessly use JWT behind the scenes.
For REST API calls, session IDs must still be included in request headers as usual. However, with JWT authentication, the session value carries a JWT with a fixed expiry time configured in Administrator. As a result, REST API scripts need to be updated to handle automatic re-authentication before or after the token expires. For more information, see the JWT Support Knowledge article.
Session-based authentication is the default authentication type. Some time after the April 2026 release, JWT will be the default authentication method. By October 2026, session-based authentication will no longer be available.
