Google Ads API: Insights Knowledge Graph Entity Capabilities Enum Reference

<>

Google has updated the Google Ads API to version 25.2, introducing critical schema adjustments for entity capabilities and creator insights data services.

Google Ads API v25.2 Schema Updates and Entity Capabilities

The transition from version 24 to version 25 of the Google Ads API updates insights_knowledge_graph_entity_capabilities.proto, altering how marketers target content creator insights and brand metrics. According to the Google Ads API release notes, version 25.2 adds a dedicated BRAND entity type under value 4.

The update also renames service namespaces across core methods. References to google.ads.googleads.v24.services.ContentCreatorInsightsService.GenerateCreatorInsights shift to the v25 namespace. These adjustments affect fields like GenerateCreatorInsightsRequest.search_attributes.creator_attributes and GenerateCreatorInsightsRequest.search_topics, ensuring developers align queries with current schema definitions.

Enterprise Knowledge Graph and Entity Reconciliation API

Complementing the Ads API changes, the Google Cloud Enterprise Knowledge Graph service organizes siloed corporate data through standardized mapping and AI-driven deduplication. According to Google Cloud documentation, the Entity Reconciliation API uses a lightweight, AI-powered semantic clustering service for tabular data to help customers join internal records with third-party datasets.

The reconciliation engine reads relational data from source BigQuery tables, extracts knowledge to build Resource Description Framework (RDF) triples, and clusters entities into matched groups. Stable Machine IDs (MIDs) serve as unique identifiers for each resolved cluster. Developers utilize the Google Knowledge Graph Search API to query these entities using standard schema.org types compliant with JSON-LD specifications, linking private business data directly to global cloud MIDs.
