The April 2025 release of Application Integration includes the following important notice.
Support for OAuth 2.0 authentication for service connectors
Effective in the April 2025 release, OAuth 2.0 authentication for service connectors is available for preview. OAuth 2.0 is a standard authorization protocol that provides specific authorization flows for web applications and helps in the secure transmission of information between web services.
Preview functionality is supported for evaluation purposes but is unwarranted and is not supported in production environments or any environment that you plan to push to production. Informatica intends to include the preview functionality in an upcoming release for production use, but might choose not to in accordance with changing market or technical circumstances.
