Groundtruth Reporting API
Read-only external reporting API (the "demand" API) for pulling GroundTruth campaign performance out of the platform and into a partner or agency reporting stack: account, organization, campaign, ad group and creative totals and daily series, product-level breakdowns, location and secondary-visit location data, audience and behavioral segments, web engagement, and CTV/OTT and audio metrics. 59 GET operations described by an OpenAPI 3.0.1 document, fronted by AWS API Gateway. Authenticated with the same paired X-GT-USER-ID and X-GT-API-KEY headers; credentials are requested from GroundTruth support. The provider notes that all endpoints currently require HTTP/1.1.
