Authentication
Google OAuth 2.0 access token for the Real-time Bidding API oauth2 discovered Set up OAuth ↗
Authorization: Bearer <credential>

Create or use a Google Cloud project in the Google Cloud Console, enable the Real-time Bidding API for that project, and obtain Google OAuth 2.0 credentials. The Buyer APIs get-started guide says Real-time Bidding API authentication uses OAuth 2.0 and gives a service-account example, so the easiest path for server-to-server integrations is to create a service account in Google Cloud, grant it access to your Authorized Buyers account, and mint access tokens with scope https://www.googleapis.com/auth/realtime-bidding. See Get Started and the API discovery doc.
