Effective in the October 2025 release, session-based authentication is deprecated.
Informatica intends to drop support for session-based authentication in the October
2026 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 (JWT). Starting on November 3, 2025, organization administrators have the
option to switch from session-based to JWT-based authentication on the
Organization
page in Administrator. Once enabled,
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, now the session value carries a JWT with a fixed expiry time configured on
the
Organization
page. 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.
In the October 2025 release, session-based authentication will remain the default.
Starting in April 2026, JWT will become the default authentication method. By
October 2026, session-based authentication will no longer be available.
If your organization uses
B2B Gateway
,
API Manager
, or the REST V2
Connector, don't select the JWT option in the October 2025 release. The JWT
option for
B2B Gateway
and REST V2 Connector
will be available in a future release.
