Quantcast Platform GraphQL API
The Quantcast Platform GraphQL API (v2) is the primary programmatic interface to the Quantcast advertising platform. It exposes queries and mutations for reporting, campaign and line item management, audience operations, and account administration. Authentication uses OAuth 2.0 client credentials issued from the Quantcast Platform profile settings; tokens are short-lived (1 hour) and passed as bearer tokens. Rate limits are enforced per token. The full schema (queries, mutations, objects, enums, input objects, scalars) is documented on the developer portal but is not published as a downloadable OpenAPI or GraphQL SDL artifact.
