Authentication in Pega Connect-REST?

Pega Connect-REST supports multiple authentication schemes, including OAuth2, basic authentication headers, and custom headers.

OAuth2 is recommended for authenticated applications.

Basic authentication can be used if user identities are required, but these types of applications are often vulnerable to attack and require additional security measures.

Custom headers can be used to provide session-based authentication, where the header is passed with each request and contains authentication information.

Custom headers require additional development effort, but can provide more control over authentication and greatly improve security.
