Teams can create campaigns, change names, budgets and schedules, then pause, resume or cancel them. Status endpoints report whether one campaign or a batch is serving, under review or blocked, while lookup endpoints expose billing accounts, eligible experiences, campaign options and creative libraries.
Authentication supports user-owned API keys and OAuth2 with separate campaign read, campaign write and billing read scopes. Campaigns created through the API use the same backend and appear in Ads Manager. Funding methods must still be added in the dashboard; group-owned keys are not supported, and performance reporting is planned for a later Analytics API release.
