Leveraging OAM Auditing functionality through OAM API - OAM 11gR2

We are using 11g R2 and we have a requirement that we need to perform some pre Authentication steps in our custom login page.

How ever we want to make sure the credential submitted by the user are valid before performing pre Authentication steps.

If the  submitted Authentication is invalid we need to create an audit entry in OAM even before making a call to auth_cred_submit.

Can we use the rest api to achieve this? OAM Rest api has the following Authentication methods

• Authentication for a Client Token
• Authentication for a User Token
• Authentication for an Access Token
