The July 2026 release of Data Integration includes the following important notices.
Deprecated support
Effective in the October 2025 release, session-based authentication is deprecated. Informatica intends to drop support for session-based authentication in a future release.
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 plans to replace session IDs used for user authentication with JSON Web Tokens (JWTs). The organization administrator can change the authentication type used for REST API requests on the Settings page in Administrator. If the administrator enables the 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. However, with JWT authentication, the session value carries a JWT with a fixed expiry time configured in Administrator. As a result, REST API scripts must 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. Sometime after the July 2026 release, JWT will be the default authentication method.
Note:
Don't enable JWT authentication if you use API Manager or if you use REST V2 Connector to call IDMC APIs. API Center, which replaces API Manager, supports JWT authentication.
