Is this statement true about using the IdentityNow APIs?

SailPoint IdentityNow APIs are not authenticated using client certificates. Instead, they use OAuth 2.0 for secure authentication and authorization. API consumers are required to obtain an access token, which is used to authenticate requests made to the IdentityNow API. The token is typically obtained by sending client credentials (client ID and client secret) to the IdentityNow authorization server, which grants the token for API access.

Key Reference from SailPoint Documentation:

API Authentication: SailPoint IdentityNow uses OAuth 2.0 for API authentication rather than client certificates. Detailed steps on how to implement OAuth-based authentication are available in SailPoint’s API documentation.
