Steps for beginning to use Enterprise DLP API like getting
Oauth access tokens.
You can access DLP data using the DLP APIs.
To get started, simply retrieve your access tokens. You can create
up to three tokens. When you initially create a token, you’ll be
issued both an access token and a refresh token. You must send the
access token in your header. Access tokens expire after 60 minutes;
before expiration, refresh the token. Refresh tokens expire after
6 months.
