The SAPIENT CORE API uses OAuth2 authentication.
To request the authorization token you need to create API credentials (Client ID and Secret) on the system first. If you have not done it already, log into your account and go to API Credentials or follow the link [add a link here with the path to the API Credentials menu]. Use the credentials to retrieve the authorization token.
NoteMake sure you copy the Secret and keep it secure as you will not be able to view it again on the system.
