The April 2025 release includes the following important notice.
Effective in the April 2025 release, Informatica dropped support for password-based OAuth 2.0 grant type for Zendesk connections in Application Ingestion and Replication. This change aligns with
Zendesk's updated security protocols. If you are currently using OAuth 2.0 to connect to Zendesk, you need to switch to Basic authentication.
