How to Get Your Google Display & Video 360 API Key
Blog post from Unified.to
The Display & Video 360 (DV360) API, part of Google's Marketing Platform, relies exclusively on OAuth 2.0 for authentication, eschewing traditional API keys or static tokens. For backend integrations, service account authentication is recommended, while three-legged user OAuth is suitable for multi-tenant SaaS where customers connect their own DV360 accounts. Access in DV360 is determined by user roles within its hierarchy of partner, advertiser, campaign, insertion order, and line item, without the need for userProfileId or developer-token reviews, which simplifies setup compared to other Google products like Campaign Manager 360. The API has specific OAuth scopes and hard rate limits, and integrating it involves enabling the API in Google Cloud, creating either service account or user OAuth credentials, assigning the necessary user roles in DV360, and managing access scopes carefully. Unified.to offers an alternative by providing a single API across multiple advertising platforms, simplifying integration and maintenance tasks such as credential management and role auditing for DV360.
